Carl Martin Bass Drive User Manual

Manual BassDrive

The Carl Martin Bass Drive

is a tube driven pre-amp/

overdrive designed for the

discriminating bass artist

of today. Whether playing

through any of the modern

solid-state/digital bass rigs on

the market or a true tube

amplifier, the Bass Drive

offers you an extra dimension

to your tone! Many of the

solid-state/digital bass

rigs today sacrifice some

warmth and edge for clinical

precision and tightness...the Bass Drive adds that classic sound (plus overdrive) back into

your amp without changing it's original tone or sound(think John Entwhistle, John Paul

Jones and Jack Bruce).

Fiendishly simple to use with
separate Volume and Gain
controls plus a basic EQ
(Bass, Middle & Treble), the
12AX7 pre-amp tube supplies
up to +40dB of extra Gain..
taking you from just a slightly
edgier tone to full out pre-amp
tube distortion! We have
designed and created our
circuitry however, to make
sure your affected tone blends
or melts into the sound of your
rig, rather than sit on top like
so many other pedals on the

market.... The Bass Drive

acts and reacts to your playing very much like the front end of a tube amp, giving you the

best of both worlds at the click of a switch....and your bass rig sounds exactly like....your

bass rig! Total transparency!

The Carl Martin Bass Drive is

housed in our famous

low-profile metal housing in

conservative black, with easy

to read and adjust Chrome

knobs and a vented

chamber for the 12AX7

pre-amp tube to live in.

Power is supplied via AC

cable and a regulated +/-12V

power supply (built in) which

allows us to use much higher

end components and supply

you with the extra headroom

and quality you have come

to expect from Carl Martin.

A simple 5 second set up is important for any gig....plug your bass into the input (or from

your tuner), and then connect the pedal output to the input on your amplifier, plug in your
AC power, NOTICE ALWAYS CHECK IF THE AC SELECT SWITCH IS SET CORRECT
turn on the effect with the footswitch and start setting up your new tone! Engage the
Drive control by turning it slightly clockwise and then bring your volume up to your normal
playing volume (again turning clockwise increases your volume). Adjust your Bass
Middle and Treble controls to bring your guitar to it's optimum tone, and then add Gain
until your are satisfied with your new sound (you may have to adjust your volume down
as you increase Gain to maintain a consistent volume level)! Engage and disengage with
the footswitch as required, and transport yourself back to the 60's and 70's while enjoying
the razor sharp precision of your contemporary bass rig!
