It s been 2 weeks now with my M13, and have to admit its just not my thing. This is only my opinion Im not posting this to stir things up, Im posting this because this forum was a huge part of my decision to buy this unit. The Distortion, Overdrive, and filters are just not usable. The distortions and overdrives are very hollow and the filters are fun at first but nothing I would ever use. The Mods again are fine but just dont cut it. If you have a favourite pedal you use chances are this is not going to match the effect. It didnt in my case The delays are Great I have no problems here but I paid 700$ CND for this thing and its just not worth it for delays. In a live setting its not as easy as having your Favourite pedal in front of you where you can tweak it as you go, I understand what they tried to accomplish with the single pedals but I still found myself flipping from one effect to another trying to get the sound right, you end up putting so much thought into it you lose focus. You can try to set this up at home but its never the same as in a jam or live show. Ive decided this thing has to go. Thanks for reading.
