Mad Professor Big Tweedy Drive - Factory

Big Tweedy Drive will deliver the iconic snarly bite and the rich saturation of the late 50´s American amplifier.

Control options:

• 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.

Electrical specifications:

• Current consumption: 10 mA at 9VDC

• Supply voltage range: 7.5V to 12V (9V recommended, the sound of the pedal depends on supply voltage)

• Input impedance: 220kOhm at 1kHz

• Output impedance: 1kOhm

• Complete bypass (true bypass)
