The Triptychon is a preamp and overdrive pedal designed to reproduce classic British amplifier tones in a pedal format. It is inspired by three distinct eras of high gain amplifier sounds, selectable via a three mode switch. The pedal provides controls for gain, tone shaping and output level to adapt to different guitars and amplifiers. It is designed to function either as a standalone drive pedal or as a full preamp into a power amp or effects return. The circuit is fully analog and voiced for dynamic response and clarity. The Triptychon is intended for guitarists seeking vintage to modern British style overdrive tones.
