Six tremolo modes, from subtle to psychedelic
Guitarists at Sweetwater know that the basic tremolo effect can take on many forms — that's why we're so excited about the MXR M305's multiple tremolo modes. Simply press down on the Gain control to cycle through them. Here's what they cover:
- MXR:Â Re-creates the vibrant, rich pulsations of the classic M159 Stereo Tremolo
- Bias:Â Based on the "lush, power-soaked compression" heard in '60s tube amplifiers with built-in tremolo circuits
- Revo:Â Based on an optical tremolo waveform, reversed for more exaggerated peaks and dips
- Opto:Â Based on photocell tremolo circuits found in vintage amps, with a lush, smooth character
- SQR:Â Square-wave tremolo for choppy, pronounced tremolo
- Harm:Â Based on the harmonic tremolo found in vintage amps, for trippy phase-like modulation
