The Sole Pressure by HAO is an overdrive pedal designed to recreate the classic sounds of the legendary '59 Tweed Bassman 4x10 combo. It features carefully selected components that allow the user to dial in the smooth, creamy overdrive of this classic amp, including the characteristic low-end sag unique to the combo version. The pedal offers dual knobs to control Output and Drive levels, along with 3 switchable EQ curves for plentiful tonal options without compromising the guitar sound. This dual control configuration also allows the Sole Pressure to act as a semi-clean booster to coax more character out of the amp.
Technical Specifications:
- Input Impedance: Approximately 1M-ohm
- Output Impedance: Approximately 10K-ohm
- Controls: Drive, Level, 3-Position mini EQ Switch (Normal, Bright, Warm)
- Size: 115(L) x 64(W) x 30(H) mm (excluding knobs, switches, and jacks)
- True Bypass Switching using a 3PDT mechanical switch
The pedal is handmade and features a built-like-a-tank steel chassis with rugged, yet stylish ABS side cheeks. It operates on 9 volts.
