Controls:
- SENSITIVITY: Adjusts the amount of distortion and compression.
- LEVEL: Controls the output level.
- ACCENT: Manages pick attack and brightness.
- CONTOUR: Adjusts the brightness of the output, with a darker tone when
adjusted counter-clockwise.
- HOT/COOL: Offers a +10dB or +6dB boost.
Electrical Specifications:
- Power: 9VDC (negative terminal at DC-jack tip)
- Power consumption: 13 mA at 9VDC
- Input impedance: 2MOhm (Predrive) or 430 kOhm (Overdrive)
- Output impedance: 50 kOhm
- Using DC-power jack removes the battery from the circuit.
Additional Information:
- The pedal allows for a combination of the two drives, offering an organic
tonal feel and the ability to easily transition between clean and overdriven
guitar tones.
- Both drives sound excellent on their own, with the ability to retain the
character of the guitar and pickups chosen.
- The pedal is designed to keep the original sonic footprint intact,
providing warm sustain to ease playing.
