The Evolution Orange Underdrive by Mad Professor is a unique pedal offering a new approach to tone manipulation. It is designed to provide cleaner tones from overdriven tones, a concept referred to as underdriving. The pedal is particularly suitable for use with vintage single-channel amps that excel when pushed to overdrive.
Key Technical Specifications:
- Input Impedance: Approximately 500K
- Output Impedance: Approximately 5K
- Current Draw: 10 mA at 9V
- Voltage Supply Range: +8V to +18V DC
Controls:
- Midrange: ± 15 dB at 400Hz
- Treble: ± 15 dB at 7KHz
- Bass: ± 15 dB at 100Hz
- Volume: Sets the overall volume level when the pedal is engaged
Functionality:
The Evolution Orange Underdrive allows users to tailor their cleaner tone
using the four control pots. By lowering the midrange, which is where the
overdrive primarily resides, users can dampen the amplifier input with the
Volume control and then adjust the Bass and Treble to customize the clean
tone. Additionally, the pedal can be used to boost the mids by setting the
Midrange and Volume up.
Use Cases:
This pedal is ideal for guitarists seeking to maintain clarity and sparkle in
their tone while playing predominantly dirty. It can serve as a valuable
companion to vintage amps being run hot, allowing the amp to remain in its
sweet spot while the Evolution Orange performs cleanup duty.
