This effects unit is in pristine condition. It is used but not on stage - immaculate with everything working. I understand it is no longer available making this a steal for any guitarist who loves experimentation and wild original sounds. 

The m13 is a very, very, very powerful device with 72 effects models, a 30 second looper, and massive configurability.

- Effects ONLY, no amp or cab models.
- Contains all the models from the DL-4, DM-4, MM-4, and Verbzilla.
- Four "strips" with three foot-switchable effects each for a total of 12 effects presets available with one click.
- One effect per strip can be on at a time; in other words, up to four effects at a time.
- Any effect model can be set to run on any strip. You can have a board full of delays if you want, or put an overdrive, a chorus, and a reverb on one strip, or any combination you can think of.
- There are also "scenes" which are similar to banks on other multi-effects units. Each scene can have a completely different set of effects on it, which means a total of 144 possible effect presets.
- It has a built-in looper which can record up to 30 seconds of sound. You can insert the loop at any point in the effects chain.
- The master tap tempo switch sets the tempo for any time-based effect you want.
- True relay bypass is available (more on that later).
- It has a tuner, an effects loop (more on that later), and so many options.
