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!
