Fulltone Bass Drive Mosfet User Manual

Congratulations on your purchase of the

With extended Bottom-end response....the first channel is the "Overdrive Mode" capable of Clean Boost (Comp-Cut) or more distorted Overdrives.

(“FM“ and “Vintage“ modes) The Tone control is a very effective circuit that can smooth out or enhance upper harmonics, with 12 O'clock being about
neutral. There's also a foot-switchable second channel "Boost Mode" Distortion control capable of higher gains with a more singing sustain! This pedal
gets its natural sound through the use of Asymmetrical-Clipping (Vintage mode), my proprietary "Flat Mids" circuit (FM mode), and now the added option of
MOSFET mode (Metal Oxide Field Effect Transistor) you can get very stinging Marshall/Ampeg/Fender-style distortions making this one of the most
versatile Bass OD/Distortions on the planet.

Features:

In jack:Plug cord coming from guitar into this....remember to unplug cord when not using for longer battery-life.

Because the Bassdrive uses mechanical True-Bypass switching, the power consumption is significantly lower than many other pedals so your battery
should last a month or longer if you remember to unplug. Current Draw for this pedal is only about 8 milliamps (8ma.)

Out jack: Plug a cord from this jack to other effects or to the amplifier.
DC power jack: This unit will work with most guitar effects 9 volt DC adapters with a Negative Center pin!

Most adapters are noisy and supply poor DC power so choose only a regulated one such as our Fulltone FPS-1.
Cool feature!

DC power jack......this jack is True Bypass as well!

And you don’t have to unplug your Bass from the Input Jack AS LONG AS you have an adapter plugged into the DC Jack.
Battery access: To access 9 volt battery simply loosen (by hand) and remove the 4 rubber feet/screw and pull the housing apart. There is no need to

over-tighten the 4 screws, just re-install them hand-tight.

both the hi-end and the upper Harmonics. Turning this clockwise increases brightness.
Turning counter-clockwise smoothes out sound without changing either the Midrange or the Bass content.

Overdrive Mode: This knob controls the distortion levels for the "Overdrive Mode only (note: the Left-side LED is lit by itself without the Right-side LED
being on). Turning this CW will increase Overdrive and sustain. This channel is voiced for transparency for the purist who's happy with his/her /Amp tone
and just wants to enhance the gain and sustain.

Boost Mode:
transforms the pedal into a medium to higher-Gained distortion with a nice midrange growl and lots of sustain. You can control the amount of distortion.
(regardless of where OD knob is set!)

Note
Comp-CutTM

add slight distortion to this via the Overdrive and Boost knobs...CAUTION! this mode can give a huge gain increase at higher OD and Boost settings so
back-off on the Volume level at first. When "Overdrive" and "Boost" levels are below 10 O'clock, this change is heard as a quicker and firmer attack with

less softness. Because there is little compression at lower OD settings, you may have difficulty hearing the subtle difference when using Comp-Cut....listen

for the attack and more immediate transients.

Note

changes done to the clipping section of the pedal…and Comp-cut Mode removes the clipping from the circuit!

FM Mode

You can leave a battery hooked up inside your pedal without any draining of its power AS LONG AS you have an adapter plugged in to the

: This pedal has True-Bypass with LED indicators! when this pedal is Off, it's not loading down your signal like virtually every mass-

: Raise or lower this to increase or decrease overall level of both channels.

: This affects both channels, Since this pedal stays true to your original sound, I made this a Presence control for rolling-off or accentuating

Actuated by stepping on the "Boost" footswitch located at the lower right, (note: both Left-side and right-side LED's must be lit) this

: Boost Mode will not operate unless the pedal is turned on with the Left LED lit and the Right LED lit as well

: this setting (on the mini-toggle switch) accesses the Clean boost mode for both channels! You can get serious clean volume increase and

: When in Comp-Cut Mode, there is no sonic difference between FM, Vintage, Mosfet or Normal Modes. Why? Because all of these modes are

this setting (on the mini toggle) makes the “Overdrive Mode” (channel A) very transparent, and you’ll notice that the Bassdrive cleans up much

better when your volume knob is turned down as well. I have enhanced (exaggerated) this lack of midrange and it sounds great. The “FM Mode” Boost
channel (channel B) is rich in midrange and gain but has a bit more high-end (frequency @5Khz) than in the “Vintage Mode” Boost channel.

Vintage Mode:

more midrange. You may notice that the “Vintage Mode“ Boost channel (channel B) has a little Less treble than the “FM mode” Boost channel.
MOSFET Mode:

when utilizing all the options available via FM and Vintage Modes.

Your pedal ships with a 9 volt battery installed, use any available 9 volt except rechargeable types. Use a REGULATED 9-volt DC power Supply like the

Fulltone FPS-1 or a professional quality multiple pedal power such as the Voodoo Labs Pedal power.
You may run this pedal anywhere between 9 and 18 Volts DC as long as the center Pin is Negative...You'll be amazed at the sonic differences! But

please make sure that you use a REGULATED quality power adapter…not a Radio Shack .
Fulltone products carry a 5-year warranty to the original owner with proof of purchase. There is no need to contact us to register your pedal, but keep a

WARNING! Damage resulting from the use of ANY power supply other than Fulltone FPS-1 is not covered by warranty...period! We are seeing

many pedals (not just Fulltones) burnt up by people using the wrong power supplies.....AC is Alternating Current.....DC is Direct Current!…you

CANNOT put AC (Line 6 adapters!) into a pedal that requires 9-18volts DC!

this setting (on the mini-toggle) takes the “Overdrive Channel (channel A) back to the Midrange heavy beast it was in the ‘90’s....You’ll hear

this new Mode applies Mosfet Clipping, which has more bottom-end, more growl, and nice overtones for a vast array of additional tones
