Description

Quick Product Summary

The MXR M305 Tremolo is a versatile modulation pedal that packs six distinct tremolo styles into a compact MXR enclosure. From smooth vintage amplifier pulse and harmonic tremolo to sharp square-wave chopping, it offers a broad range of traditional and creative modulation sounds.

This used example is in Good condition, with visible signs of previous use consistent with a pre-owned effects pedal. Advanced features including stereo operation, Envelope mode and external tap tempo or expression control make it equally useful for straightforward vintage sounds and more elaborate modern pedalboard setups.

What Makes the MXR M305 Tremolo Special?

The M305 offers six carefully voiced tremolo styles. MXR recreates the character of the classic M159 Stereo Tremolo, while Bias and Opto capture two familiar styles of vintage amplifier tremolo. Revo reverses the optical waveform for a more unusual pulse, SQR provides hard-edged rhythmic chopping, and Harm delivers the swirling character of harmonic tremolo.

Beyond its core Speed, Gain and Depth controls, the M305 offers attack-sensitive Envelope mode, stereo operation and external control. A compatible expression pedal can even blend between two different Speed, Gain and Depth configurations for real-time performance control.

Who Is It For?

The MXR Tremolo is ideal for guitarists who want several different styles of tremolo without dedicating pedalboard space to multiple pedals. It works particularly well for blues, surf, country, indie, alternative, ambient and vintage-inspired guitar sounds, while its square-wave and envelope functions open up more experimental rhythmic possibilities.

FAQs

How many tremolo sounds does the MXR M305 have?

It provides six tremolo styles: MXR, Bias, Revo, Opto, SQR and Harm.

What is the MXR tremolo mode?

The MXR setting recreates the character of the earlier MXR M159 Stereo Tremolo, delivering a rich and organic traditional tremolo sound.

What does Bias mode sound like?

Bias mode is inspired by vintage valve-amplifier tremolo and produces a warm, compressed pulse associated with early tremolo-equipped amplifiers.

What is Harmonic tremolo?

Harmonic tremolo modulates different frequency ranges to create a swirling, almost phase-like effect rather than simply raising and lowering the overall volume.

Can it produce a choppy tremolo sound?

Yes. The SQR setting uses a square waveform for pronounced, hard-edged rhythmic chopping.

What is Envelope mode?

Envelope mode makes the Speed and Depth react to your playing dynamics. Softer playing can produce gentler modulation, while stronger picking can create a more pronounced effect.

Does the MXR M305 support tap tempo?

Yes. A compatible external tap tempo switch can be connected to the CTR jack.

Can I use an expression pedal?

Yes. A compatible expression pedal can blend between two different configurations of the Gain, Speed and Depth controls.

Can the pedal operate in stereo?

Yes. The M305 supports stereo input and output configurations, making it particularly effective for wide, panning tremolo sounds.

Does it have true bypass?

The pedal defaults to true relay bypass, but it can also be configured for buffered bypass when required.

Can it run from a battery?

No. The MXR M305 requires external 9V DC power.

Is a power supply included?

No. No power supply is included with this used pedal.

What condition is this example in?

This example is graded Good, with visible cosmetic signs of previous use consistent with a pre-owned pedal.
