The MXR M305 is a tremolo pedal with 6 waveform modulation modes, including waveforms and rectangular waves, which have been a good choice for MXR testolo sound to simulate bias modulation system.
Exp. Pedals can be used to change the tremolo speed, seamless switching between two settings, and external tap switch control for a more expressive tremolo sound.
STEREO/MONO switch inside the main unit supports both mono and stereo inputs. Recommended not only for guitars, but also for use with keyboards and DJ equipment.
