The Chime by Pettyjohn Electronics is a studio-grade overdrive and preamp pedal designed to provide the touch-sensitive harmonic richness associated with vintage English amplifiers on the edge of breakup. It features a versatile circuit that can function as a clean boost, a foundational "always-on" sweetener, or a saturated drive with a distinctive British character. The pedal is renowned for its high internal headroom, achieved through a proprietary power supply that converts a standard input to 36V, ensuring 3D clarity and openness. Its control set includes a unique Tilt EQ, a sweepable High Pass Filter, and a clipping mix knob for blending between Germanium and LED diodes. The Chime originally derived from the right channel of the flagship PettyDrive and has since evolved into the standalone Foundry Series and MKII versions. It is handmade in the Pacific Northwest, USA, utilizing audiophile-grade components such as Orange Drop capacitors and Burr-Brown op-amps.
