MAD PROFESSOR - BIG TWEEDY DRIVE - OWNER’S MANUAL
Thank you for buying the
Mad Professor Big Tweedy
Drive pedal!
As the name says the Big Tweedy Drive
pedal is voiced after a super rare High
Powered Tweed Twin amp. The pedal
gives you the highly sought-after vintage
tone that has big fat punchy midrange
and sweet gnarly bite like the late 50’s
American amplifiers.
Like the big vintage tweed amps, the Big
Tweedy Drive has the same tactile dynam-
ics and touch sensitivity players are raving
about: adjust the amount of gain with
your picking attack or the guitar volume.
This makes the pedal fit into a surpris-
ingly broad range of genres: jazz, blues,
rockabilly, country and rock’n’roll.
The pedal stacks very well too. So you
can find the more saturated and higher
gain tones by placing a booster or an over-
drive in front of the Big Tweedy Drive for
extra gain and sustain. Or you can place the
Big Tweedy Drive in front of a clean ampli-
fier or boost an already distorted amp.
The tone controls help you to fine tune your
tone when using the pedal with different
guitars and amplifiers.
The controls are:
• VOLUME: Sets the output voltage.
• GAIN: Adjusts the amount of distortion.
• TONE: Adjusts high frequency tone.
Adjustment range is from significant high
frequency cut to slight high frequency
boost. The wide spectrum TONE control
can either soften the tone or add some
brightness to your straight signal.
• PRESENCE: You can fine tune the
shimmer and cut with PRESENCE knob
that adjusts the upper high end.
Turn both TONE and PRESENCE
knobs down for a mellow fat tone or turn
them up for a bright cutting rock tone.
The pedal cleans very well from the gui-
tar volume pot and thanks to the finely
balanced compression the volume level
will be adjusted just the right amount.
CAUTION!
Never operate the unit with its bottom
removed or damage will most likely occur.
