The MXR Tremolo’s six tremolo waveforms represent classic and iconic sources of the effect as well as new sounds concocted by the MXR design team. First, the MXR style recreates the organic sound and pulse of the much beloved M159 MXR Stereo Tremolo. Next, the Bias style takes after the lush, power-soaked compression of tremolo effects that came equipped on early 1960s tube amplifiers. The Revo style, an original innovation, turns the optical tremolo waveform backwards for more exaggerated peaks and valleys. The Opto style emulates the smooth pulsating tremolo generated by photo cells in many popular amplifiers. Inspired by an iconic outboard effect, the SQR setting produces choppy, super pronounced tremolo. Finally, the Harm style recreates the trippy, phase-like tremolo produced by certain rare vintage amplifiers.
Getting incredible sounds from the MXR Tremolo right out of the box is simple. Speed, Gain, and Depth controls set the rate, volume, and intensity of the selected tremolo effect, and cycling through the six styles is as simple as pushing the Gain knob. For advanced technicians of tone, a bevy of features await: Run the pedal in Stereo Input or Output modes using an MXR TRS Cable or TRS Splitter Cable, use an M199 MXR Tap Tempo Switch to set the rate of the effect, use an expression pedal such as the DVP3 Volume (X)™ Pedal to blend between to different setting configurations, use envelope mode for a touch-sensitive tremolo response, and more.
These and other features come in a single MXR housing so that you can put a wide variety of intriguing, well-crafted tremolo waveforms on your board with no overcrowding.

Why was my package refused?
There are a number of reasons your package could be refused by us, including:
Really good tremolo.
From helicopter chop to harmonic tremolo, it's all good. And the touch sensitivity function is icing on the cake.
Very accurate modeling of the famed m159. Awesome tonality low noise floor, stereo in and out. High definition DSP.
Great sounding, stereo, all in one.
I'm a snob when it comes to tremolo pedals, and I was dead set on NOT getting a digital one. I decided to give the M305 a shot anyway and so glad that I did. It sounds fantastic, lots of vibe and mojo. Tremolo is a funny thing. You'd think they are all the same, but they definitely are not. Every mode on the M305 has the ability to get really choppy, or stay really subtle, which is a dream. Lots of variation and everything sounds good. The one big bonus with this pedal is the dynamic envelope mode. The harder you play, the faster the tremolo goes, and it slows back down as your guitar decays or you play softer. It works very well, and after some time with it, it's almost hard to go back to a static tremolo speed that doesn't change. And it works in every single mode, including Harmonic Mode, which by the way is nice and chewy and quite lovely. Just a fantastic tremolo pedal all around.
