Electro-Harmonix Mainframe Bit Crusher
Electro-Harmonix · pedal
The Electro-Harmonix Mainframe is a digital bit crusher and sample rate reducer pedal that generates retro digital artifacts ranging from subtle grit to extreme lo-fi degradation. It independently reduces bit depth from 16 to 1 bit and sample rate from 48kHz to 110Hz, with controls for Mix, Volume, and Filter. The Mainframe spans from mild digital crunch to full 8-bit video game sonic destruction. It suits experimental, electronic, post-punk, ambient, and noise contexts where digital degradation and lo-fi aesthetics are desired on guitar, synth, or other instruments.
