Mad Professor / Big Tweedy Drive / 2017 / Effect For Sale
BIG TWEEDY DRIVE
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 dynamics 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 surprisingly 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 overdrive 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 amplifier 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.
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 PRECENSE knobs down for a mellow fat tone or turn them up for a bright cutting rock tone.
The pedal cleans very well from the guitar volume pot and thanks to the finely balanced compression the volume level will be adjusted just the right amount.

– Supply voltage range 7.5V to 12V (9V recommended, the sound of the pedal depends on supply voltage)
– Input impedance 220kOhm at 1kHz

Mad Professor Amplification Ltd, Marketing and management
Harri Koski: Guitarist, marketing, cordinating the production, helping hand.
Harri has been playing guitar since mid 70´s and his serious hobby turned into a business when he started Custom-Sounds (www.custom-sounds.com) in 1996. Custom-Sounds was a high-end guitar gear company from the beginning and it was one of the first “boutique" guitar shops on internet. His co-operation with Bjorn Juhl started the BJF pedals business and soon these two soul brothers were talking about the ultimate amplifier. Bjorn Juhl and Harri had the mad idea about designing the ultimate guitar tube amplifier and to make it right here in Scandinavia. Bjorn put on his propel-hat and Harri put all his energy and money into this project. Soon we found the right people to work with us and the world got a brand new amplifier that was not a clone of any vintage amp as these modern hand-wired amps often are. Harri has a collection of various Gibson guitars and early JV Squier Fenders and plugs these into his serial no: 000 Mad Professor prototype head that is played loud almost every day.
