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.

C A U T I O N ! 
never operate the unit with its bottom 
removed or damage will most likely occur.
