Electro-Harmonix Mainframe
Electro-Harmonix · pedal
The Electro-Harmonix MAINFRAME is a bit crusher and sample rate reducer pedal from Electro-Harmonix, delivering lo-fi digital degradation by reducing the bit depth and sample rate of the guitar signal to produce crunchy, digital fuzz and lo-fi artifacts. Controls include Bit Depth, Sample Rate, Blend (dry/wet), and a Gate control. The MAINFRAME creates 8-bit game console, degraded digital, and aggressive bit-crushed guitar tones.
