JHS 3 Series Bit Crusher Pedal
Guaranteed Safe Checkout:
The JHS 3 Series Bit Crusher is part of JHS's affordable, simplified 3 Series range, built by JHS in Kansas City, Missouri, with three simple controls and one toggle. It was built specifically to do two things with precision: reduce bit depth and reduce sample rate, with a filter to shape the result. The Crush knob controls bit depth, running from full 24-bit resolution anticlockwise through to 1-bit clockwise, moving from unprocessed tone through grainy, textured sounds into square-wave aggression and gated digital distortion. The Sample Rate knob works anticlockwise from a clean 32.768kHz down to 2.5Hz, introducing aliasing and artefacts ranging from subtle harmonic shifts to metallic, ring-mod-like chaos and full digital collapse. The Filter knob shapes both - fully clockwise is unfiltered, and turning it anticlockwise sweeps the corner frequency for more filtering. The Type toggle switches filter character: down gives a second-order low-pass filter with no resonant peak, inspired by vintage synthesisers like Oberheim and well suited to bass guitar, while up sweeps a high-pass and low-pass filter in succession, focusing a band of mid-range frequencies reminiscent of a handheld game console. JHS notes the circuit uses a "zero-hole filter" - a theoretical signal processing concept it says had not previously found a practical application before being built into this circuit.
