Congratulations
Thank you for purchasing the Yamaha B1D Divided Pickup Unit.
The B1D Divided Pickup Unit can pick up the vibrations produced by an electric bass guitar’s strings, and transmit those signals to a Yamaha Guitar MIDI Converter (G50). When properly installed and adjusted it can convert almost any steel stringed bass guitar into a controller for a guitar synthesizer system. It can be used on normal 4-string basses as well as 5-string, and 6-string basses.
To get the most out of your B1D, please read this owner’s manual carefully, and follow the installation instructions within, in order to en­sure proper operation. Also, keep this manual in a safe place for future reference.
Features
As well as any normal 4-string electric bass, the unit can also be used on 5-string, and 6-string basses. A number of installation options are provided to allow for different guitar shapes, use, and playing styles. Choose a method that best suits your bass and playing requirements.
Methods for Attaching the Divided Pickup:
Special Fittings (removable), double-sided
adhesive tape, screw.
Methods for Attaching the Controller:
Velcro fastener, bracket, double-sided
adhesive tape, screw.
One touch operation allows you to switch
between bass synthesizer sound and bass
guitar sound. Also, the synthesizer’s voice
and bass guitar’s signal can be output
separately or together, offering a wide
variety of sounds for added playing enjoy-
ment.
Of course, the bass synthesizer’s volume can
be controlled. But you can also control other
functions like octave, parameter values,
program changes (that are transmitted from
the G50’s memory), and G50’s memory
numbers (which can be changed by a value
of +1/-1).

Precautions !! PLEASE READ THIS BEFORE PROCEEDING !!␣
Location
Do not expose the B1D to the following condi­tions to avoid deformation, discoloration, or more serious damage.
• Direct sunlight (e.g. near a window).
• High temperatures (e.g. near a heat source,
outside, or in a car during the daytime).
• Excessive humidity.
• Excessive dust.
• Strong vibration.
Connections
When connecting the B1D to the Yamaha G50
Guitar MIDI Converter, be sure to use the
specified multi-pin cable (supplied with the
G50 Guitar MIDI Converter).
• Always connect the direct guitar cable (page
4), even if you don’t intend to use the direct
guitar sound. The direct guitar cable is
essential for proper grounding, to minimize
noise and prevent electric shock.
• Always unplug cables by gripping the plug
firmly, not by pulling on the cable.
• Disconnect all cables before moving the
instrument or any connected equipment.
Handling and Transport
Never apply excessive force to the controls,
connectors or other parts of the instrument.
• Physical shocks caused by dropping, bump-
ing, or placing heavy objects on the instru-
ment can result in scratches and more serious
damage.
• Be careful not to damage the B1D controller
when placing the guitar in a case or on a
stand.
Cleaning
• Clean the unit with a dry soft cloth.
• A slightly damp cloth may be used to remove stubborn grime and dirt.
• Never use cleaners such as thinner.
Notes on Adhesive Tape
• Depending on the surface of the bass guitar the finish may peel off or be altered chemically when the pickup/controller is mounted using adhesive tape (double-sided). To make sure, it is recommended that you first try this method of attachment by applying some tape at a place on the guitar body which is not visible nor­mally.
If the pickup must be removed from the base guitar,
always use a fresh layer of double-sided adhesive tape and/or cushion when reinstalling, as the adhesive properties of used tape/cushion are reduced drastically when peeled off the mating surface. Also, before attaching the adhesive tape or pickup, clean the mating surface thoroughly, as dust and grease may cause the pickup to come loose.
Service and Modification
• The B1D contains no user serviceable parts. Opening it or tampering with it in any way can lead to irreparable damage and possibly electric shock. Refer all servicing to qualified YAMAHA personnel.
Yamaha is not responsible for damage caused by improper installation, handling, or operation.

Before You Install
Installing on the Bass Guitar
Before you install the B1D on your bass guitar, carefully read the advice provided below. Select an installation method which is best suited to your bass guitar and playing requirements.
The Bass Guitar
The B1D is a divided pickup designed for use with steel string electric basses. It can be used with 4­string as well as 5- and 6-string basses. If your bass guitar is one of the types listed below, the B1D will not function properly with it.
• 8-string basses or other non-standard string configurations other than 4-, 5-, and 6- string basses.
• Nylon string or other non-metallic string bass guitars.
• Basses with extremely wide or narrow string spacing. Any bass guitar that the strings will not properly fit over the magnetic pickup ( refer to “Specifications” on pg. 18).
• Basses with extremely low string clearance. Depending upon the manner in which the pickup is attached, make sure that there is more than10­13mm (0.39"-0.51") of clearance.
The divided pickup is specially designed and adjusted for use on bass guitars with up to 6-strings, the pickup will not func­tion with 6-string guitars.
The divided pickup should be attached between the bridge and rear pickup, ideally 10-20mm (0.39"-
0.79") from the bridge. Make sure you have ad­equate space for proper installation of the pickup.
Make sure your bass’ neck (truss rod) and string height/intonation (bridge) are properly adjusted before installing the B1D.
Disconnect the Direct Bass Guitar Signal cable and the 13-pin cable from the B1D controller before installation.
Select the Method of Installation
Three methods for installing the divided pickup are listed below.
Base Plate Installation (Removable)
• Height adjustment is easily performed.
• The divided pickup can easily be removed yet pickup height adjustment is maintained.
Double-sided Adhesive Tape
• Reduces the risk of damaging the bass guitar body.
• More time and care must be taken to achieve proper pickup height.
Spring and Screw Installation
• Height adjustment is easily performed.
• The pickup can be securely attached to the bass body.
It will be necessary to drill holes in the bass
guitar’s body.
Five methods for installing the Controller unit are listed below.
V elcro Installation
• Easy removal and replacement.
Bracket Installation
• Used in conjunction with adhesive tape, the control­ler can be installed on bodies that are not flat.
• The bracket can also be attached using the bass guitar’s strap pin. However, some caution must be used to keep from damaging the strap pin screw.
Suction Cup Installation
• Easy to remove, replace and transport the unit.
• Easy to attach the controller unit to a bass guitar with a flat top and a smooth, shiny finish.
Double-sided Adhesive Tape
• Easy and secure attachment is possible.
Screw Installation
• Used in conjunction with adhesive tape, the control­ler can be installed on bodies that are not flat.
It will be necessary to drill a hole in the bass
guitar body.
* If you use the base plate attachment (remov-
able) for the divided pickup, it is a good idea to attach the controller with Velcro tape or suctions cups so it is removable as well.
Installing the Pickup Controller
Due to the divided pickup’s magnetic strength, the double-sided tape may peel off the bass guitar body if the point of attachment is weak. Also, the pickup and controller may be knocked off, if the bass guitar is
subject to strong shock or prolonged use, if an attachment method other than screw installation is used. Select a method of attachment according to installation position, and the strengths of the method of installation.

Attaching the Divided Pickup
Mark the Installation position
for the divided Pickup.
The divided pickup should be located between the rear pickup and bridge so that the cable end of the pickup is oriented toward the lower bass string (the pickup will not function if it is attached facing the opposite direction). The divided pickup is designed for use on basses with up to 6 strings (6B, 5E, 4A, 3D, 2G, 1C). If the pickup is to be used on a 4-string bass, align the 4 magnetic yokes, in the center portion of the pickup, with the strings. For 5-string basses with a [B, E, A, D, G] tuning, use the 5 magnetic yokes on the cable end of the pickup. If the tuning is [E, A, D, G, C] use the 5 magnetic yokes opposite the cable end of the pickup.
• For 4-string basses (4E, 3A, 2D, 1G)
E A D G
Place the divided pickup on the body and decide the optimum position for installation.
From the low end string side, slide the divided pickup under the bass guitar strings. Using the magnetic attraction of the pickup to the strings, adjust the position so that each string passes over its corresponding magnetic yoke.
Adjust the position of the pickup so that it meets the conditions listed below.
1. Each string must pass over its corresponding magnet.
The pickup will not function properly if the string does not properly pass over the magnetic yoke. Check that the strings pass over the magnetic yokes, even when bending the strings.

2. The distance between the divided pickup and the bridge should be about 10-20mm (0.39"-0.79").
* Make sure the pickup is not in contact with
the bridge.
* The distance can be increased to more than
20mm (0.79") as long as the strings pass over the magnetic yokes when bending the strings.

3. String height should not be widely varied.
Extreme variations in string height will result in a poor output level for the pickup (The output level can be somewhat controlled with the G50’s Gain Setting).
Page 8
Attaching the Divided Pickup
Once the optimum installation position has been decided, you can prepare to attach the pickup. However, the distance between the string and the pickup’s magnetic yoke is ex­tremely important.
Since the height of the pickup’s magnetic yokes cannot be adjusted individually, the pickup posi­tion, the pickup’s overall height, and string height, can be adjusted to meet the conditions necessary for optimum string/pickup clearance. The distance between the top of the pickup’s magnetic yokes and the bottom of each string should be about 1-2mm (0.04"-0.08") when each string is fretted at the highest note on the neck. The distance between the pickup and the bottom of the strings can be set to less than 1mm (0.04") as long as the strings do not touch the pickup when the bass is played. However, as long as other strings can be set to a height of 2.0mm (0.08") or less, try to set the E and B strings between 1.5 (0.06") and
2.0mm (0.08"). Also, the output level for each of the magnetic pickups is fairly different so after the divided pickup has been attached make sure you set Input Gain each strings with the Guitar MIDI Converter.
The chart below lists the optimum string/pickup distance and G50 Input Gain Settings for average bass guitars. Use the chart as a reference when setting up your pickup.

(Removable) Fittings Attachment
The divided pickup can easily be removed yet pickup height adjustment is still maintained.
1. Apply the base plate’s double-sided adhesive tape, to the underside of the base plate. (Do not remove the backing yet.)
2. Fix the Pickup Attachment Fittings to the Divided Pickup with the screws and springs. For proper height adjustment, select the best length screw (6, 8, 10, 12mm). To start with, loosely fix the pickup with the 6mm screws, and adjust the height after the base plate is attached to the body.
3. Use the 3x6 screws (with washer) to attach the pickup attachment fittings to the base plate.
4. With the pickup carefully positioned on the bass body, mark the position where the base plates (left/right) will be attached.
5. Remove the backing from the double-sided adhesive tape on the base plates (left/right).
6. Without letting the adhesive side of the tape come in contact with the bass body, position the base plate over the place where it is to be attached and then lower the base plate onto the body surface.
* Holding both ends of the pickup, apply light
pressure to attach the pickup to the body.
* If the base plate is to be attached with screws,
remove the pickup and pickup attachment fittings from the base plate. Drill a 2mm (0.08”, approx). diameter hole into the bass guitar’s body making sure that the hole is drilled vertically. Use the plate tapping screws (3x10mm) to fix the base plate to the bass guitar body.
7. With the bass properly tuned, use the small screws to adjust the distance between each of the strings and their corresponding pickup yoke. With each string fretted at its highest note on the neck, check the distance between each string and its corresponding pickup using the supplied clearance gauge ( pg. 7).
* To remove the base plate from the bass guitar’s
body, use a minus screwdriver to gently pry the base plate from the body, or use a pair of pliers to lift the base plate from the body. Either way, be careful not to scratch or damage the bass guitar body or the base plate while removing the base plate.
8. Once pickup height has been properly set, adjust the individual input levels on the Guitar MIDI Converter (Refer to pg. 14. Also, the Guitar MIDI Converter manual).

Attaching the Divided Pickup
Double-Sided Adhesive Tape Attachment
Use the cushions and spacers to adjust the height of the pickup, and use the double-sided adhesive tape to attach the pickup to the bass guitar.
1. Cut in half the spacers (A, B) used to adjust the pickup’s height.
2. Determine how many spacers and/or cushions will be needed to attain proper height for the pickup. With the backing still in place, stack spacers A (1mm thick), B (0.3mm thick), and the cushion underneath both ends of pickup (with the pickup underneath the strings) until proper clearance between the strings and magnetic yokes is achieved ( pg. 7). Do not remove the backing from the cushions or spacers when initially setting up the pickup height. Initially use spacers A (1mm thick) and the cushion to gain the approximate height necessary, then use spacers B (0.3mm thick) to fine-tune the height of the pickup.
* Before you adjust the pickup height, make sure
that the bass guitar is properly tuned.
* Please note that the cushion/spacer backing
adds about 0.1 millimeter to their thickness, so take this added thickness into account when using a number of spacers.
* If the body surface is not flat, use the double-
sided adhesive tape or cushion to attach the pickup to the bass guitar body so that the pickup properly adheres to the body.
* If you need to compensate for differences in
height between the low and high strings, cut the double-sided adhesive tape and cushion into one-quarter or one-third widths and adjust the height.
3. Once the number of pieces has been deter­mined, apply the cushions (with double-sided adhesive) or double-sided adhesive tape to the bottom of the pickup, then apply one spacer and check the clearance with the clearance gauge while the highest note on the neck is fretted ( pg. 7). Add spacers one by one,
continually checking the clearance, until the proper height is attained. Do not remove the backing from the tape that is used to attach to the pickup to the bass guitar body until you are sure that proper height is achieved.
4. Once the proper height is achieved, remove the backing from the tape used to attach the pickup to the body. Keeping the exposed tape from coming into contact with the body, slide the pickup under the strings. From the high string side of the bass guitar, slide a minus driver or similar tool under the strings, to help support the pickup from the opposite side. Once the pickup is slid into position, attach the pickup/spacer assembly to the body.
* Make sure that the bass body is free from dust
and oil which might prevent the adhesive from sticking to the body.
* Holding both ends of the pickup, apply light
pressure to attach the pickup to the body.
5. Once the pickup is attached and the height has been adjusted, adjust the input gain levels on the Guitar MIDI Converter (Refer to pg.
14. Also, the Guitar MIDI Converter manual).
* To remove the divided pickup from the body
without causing damage to the bass body, leave the spacer attached to the body in place and gently pry off the second layer spacer.

Attaching the Divided Pickup
Use the following steps if you need to read­just the pickup height.
1. Determine the number of spacers you need to add or remove.
2. Remove only the pickup from the body. Without applying any excessive force to the pickup, carefully pry the pickup from the spacers by sliding a thin, flat object under the low string end of the pickup, and gently lifting the pickup away from the spacer.
* Bending or twisting the pickup may cause
the coil inside the pickup to snap, resulting in a damaged pickup. Use caution.
3. Carefully remove the double-sided tape from the underside of the pickup.
4. Readjust the height as required. If spacers must be added, remove the double-sided tape from the existing spacer. If spacers must be removed, be sure to remove both the spacer and its double-sided tape.
Screw and Spring Attachment
It will be necessary to drill holes in the bass guitar body to attach the pickup with screws and springs.
1. Place the pickup in the position in which it will be attached, then carefully mark the centers of the two screw holes at either end of the pickup on the bass guitar body.
2. Drill the screw holes. Carefully drill a 2mm (0.08", approx.) diameter hole at both marked locations. Make sure that the holes are drilled vertically.
3. Insert the springs into the underside of the pickup, insert the tapping screws (3x25) through the screw holes and springs, and screw the screws in the holes in the body.
4. With the bass properly tuned, adjust the pickup height by loosening or tightening the pickup screws. Adjust the clearance while the highest note on each string is fretted. Pickup clearance can be checked using the supplied clearance gauge ( pg. 7).
5. If proper clearance is achieved, adjust the input gain levels on the Guitar MIDI Con­verter (Refer to pg. 14. Also, the Guitar MIDI Converter manual).
Tapping Screw
3x25
5. Finally, attach fresh double-sided tape or a cushion to the bottom of the pickup, remove the backing, carefully attach the pickup to the uppermost spacer.
6. Re-tune the bass and check the clearance with the supplied clearance gauge.
7. If proper clearance is achieved, adjust the input gain levels on the Guitar MIDI Converter (Refer to pg. 14. Also, the Guitar MIDI Converter manual).
