Description
The MXR M305 Tremolo is a versatile and performance-ready guitar pedal, boasting a plethora of tremolo styles. This compact yet powerful device represents the full spectrum of the iconic tremolo effect, ranging from vintage classics to modern interpretations crafted meticulously by the MXR design team.
Explore six distinct tremolo waveforms. The MXR style harks back to the beloved M159 MXR Stereo Tremolo, replicating its organic sound and pulse. The Bias style emulates the lush, power-soaked compression of 1960s tube amplifiers. The Revo style, an MXR innovation, reverses the optical tremolo waveform for more exaggerated peaks and valleys. The Opto style delivers the smooth pulsating tremolo generated by photocells in popular amps. The SQR setting offers choppy, super pronounced tremolo inspired by iconic outboard effects. Lastly, the Harm style recreates the phase-like tremolo of certain rare vintage amplifiers.
Getting started with the MXR M305 Tremolo is a breeze. Manipulate the Speed, Gain and Depth controls to adjust the rate, volume and intensity of your chosen tremolo effect, and switch between the six styles with a simple push of the Gain knob. Advanced users will appreciate the additional features like stereo operation, tap tempo, expression pedal functionality, and envelope tremolo, which dynamically adjusts the effect to match your playing intensity.

- Six masterfully tuned styles: MXR, Bias, Revo, Opto, SQR, and Harm
- Easy operation with Speed, Gain, and Depth controls
- Advanced features: stereo operation, tap tempo, expression pedal functionality, and envelope tremolo
