FEATURES AND FUNCTIONS

1. IN: 1/4" input jack for your guitar.

2. OUT: 1/4” output jack connection to your amp.

3. PSU: Connection for 9-12 volt DC (center pin negative ).

4. BYPASS: Footswitch toggles between overdrive and clean bypass. An
on/off LED status indicator illuminates when the overdrive is active.

5. TOGGLE: Choose between the two overdrive channels by depressing
the footswitch. Channel-1 is voiced for rhythm guitar while channel-2 is
augmented in the mid-range to increase sustain and cut for solos. An LED
status indicator illuminates when channel-2 is active.

6. DRIVE: Used to adjust overall amount of overdrive.

7. TONE 1 & 2: Both channels are equipped with a tone control that lets you
adjust each channel to your specifi c needs.

8. BITE 1 & 2: Both channels are equipped with a 3-position BITE switch that
allows you to assign each channel a different voicing. Choose between
a vintage style overdrive (OFF), an extra beefy sound (MID) or a more
aggressive modern (MAX) tonal structure.

9. LEVEL 1 & 2: Both channels are equipped with a level control that lets
you adjust the overall output volume of each channel separately. Think of
these like the master volume control on a guitar amplifi er.

CONGRATULATIONS on your purchase of the Bones Texas overdrive.
The Texas is a high performance overdrive pedal capable of generating
everything from vintage ‘TS9’ style tones all the way to the latest ultra
high-gain ‘in-your-face’ tones. Inside is a drive circuit that can add bluesy
textures or, when driven hard, will produce harmonically rich tones that are
fatter than a Texas Longhorn and more fun than a rattlesnake neck tie!

For maximum on-stage effi ciency, the Texas is confi gured for clean, rhythm
& lead playability. In bypass mode, you get the natural clean sound of your
guitar. When activated you can Texas two-step between two overdrive
channels. Channel-1 is designed for rhythm guitar tones. Channel-2 is
augmented in the mid-range to increase sustain and cut for solos.

Both channels are equipped with a tone and level control that let you tailor
each channel to your specifi c needs. For instance, you can set the rhythm
tone with extra high-end to cut through at lower volumes while the lead
channel can be set with more bottom-end to fatten solos. To further beef
up the sound both channels feature a 3-position BITE switch that lets you
assign a different voicing to each channel.

The Texas is a high performance overdrive pedal that delivers a range of
tones as wide as the Dallas sky in a compact and easy to use format.

POWERING THE TEXAS OVERDRIVE

Bones pedals require an external power adapter that outputs 9 to 12 volts
DC with a 2.1mm barrel jack wired center pin negative . Bones
pedals will draw a max of 100mA. Possible damage may occur if another
type of power adapter is used. Consult your dealer for more information.

CONNECTIONS AND SETUP

Before you begin, turn your guitar amplifi er OFF. Connect the power supply
adaptor. The LEDs illuminate when a footswitch is depressed indicating the
pedal is powered up and ready for use.

To start, place the pedal in bypass mode by
depressing the BYPASS footswitch (LED
off) and set the controls as pictured. This will
give you a good starting sound while getting
to know your Texas overdrive.

Connect your guitar to the IN jack.
Connect the OUT jack to your amplifi er.

Always test your connections with your amp set at a low volume level. Turn
your amp on. If no sound is heard check the guitar and power connections.
Turn your amp up to a comfortable playing level. While in bypass mode set
up your clean (or not so clean) sound on your amp.

Activate the pedal by depressing the BYPASS footswitch (LED on). Select
channel-1 by depressing the TOGGLE footswitch (LED off). Adjust the
LEVEL-1 control so the volume is a little louder than the bypassed volume.
Depress the TOGGLE footswitch again and set up the LEVEL-2 control a
little louder for solos and you’re ready for the roughest roadhouse.

You will fi nd that most of the controls are intuitive and extremely sensitive
to changes. Small control adjustments will make big changes in the sound.
Take your time, experiment and have fun.

FREQUENTLY ASKED QUESTIONS

Can I use any 9 volt adapter to power the Bones?

There are many adapters that can supply 9-12 volts DC but to be compatible the adapter must also have a 2.1mm barrel plug wired center pin negative. The Bones draw
100mA of current to operate. Your adapter can be rated higher, for example 500mA, but not lower.

I hear a high frequency “whine”. What causes this and how do I get rid of it?

Most likely this is caused by the power adapter you are using. Some switching type power adapters can make noise that bleeds into the guitar signal. If you encounter high
frequency noise try a different adapter. We recommend standard linear adapters although we have successfully tested the Bones with both types.

Is the Texas a true bypass pedal?

No. The Texas features active buffering in bypass mode that lowers the output impedance allowing longer cables without noise or tone loss. This also enables us to employ
EIS - Electronic Impulse Switching that eliminates certain problems with true bypass designs. True bypass switching can be noisy when switching pedals on and off produc­ing pops and clicks. If used in conjunction with high-gain amps that “pop” can become a loud “bang”. The EIS switch is 100% noiseless.

Which is better, True Bypass or Buffered Bypass?

Buffers are a good thing to have in your signal chain. They regulate your signal and lower the output impedance to drive long cables and dirty (oxidized) jack contacts.
However, buffers have received a bad reputation because some manufacturers design their buffer circuits to save money. That design strategy limits overall sound quality
of the bypassed signal and has created a demand for a better system. The simplest alternative was to do away with the buffer and provide a hard-wired bypass via a me­chanical switch and the term “true bypass” was born. But this arrangement has a downside too. Mechanical switches can make noise and are less reliable than electronic
switching. The Bones are designed with a great sounding class-A buffer that emulates the input impedance of a typical tube amp. With a well designed buffer you get less
noise and great tone.

Why can’t the Texas be powered by a battery?

It’s because of the class-A topology. Class-A circuits sound best but are power hungry and will drain a battery in no time.

How should I set the sound on my amp?

The Texas is a two channel pedal based on the “clean, rhythm, lead” concept. The two channels in the Texas can supply the chunky rhythm tones and searing lead sounds
while your amp provides a base “clean” sound. Think of your amp as a blank canvas and the Texas as a pallet full of different color paints.

I use several pedals. Where’s the best place to put the Texas in my signal chain?

There are no rules but there are general guidelines when it comes to overdrive pedals. If you place a booster before an overdrive it will increase the amount of saturation but
your guitar volume will stay about the same. If the booster is placed after it will increase your guitar volume without changing the tone of the pedal. Placing the Texas before
pedals like a chorus, fl anger and phaser will make their effects more prominent because of the increased harmonics the distortion adds. Experiment and have fun.
