I only tried it in store, but I post anyway because there's no Carl Martin of mass opinion. This pedal is very effective if you want a marshall, the drive begins and ends Légé crunch on a hot rock, well rounded, not at all aggressive. Three pots for this channel: drive, level and wave. I found the saturation nice, but nothing exeptional (if you like, prefer the plexi tone that has an overdrive channel and a channel distortion). Against by the boost is huge, especially in his clear, he adds a very light color and an amazing potato ...
Carl Martin AC may seem expensive but they do not blow integrated power supply, their sound is very good at what they do, and in addition they are dannois, it changes a little from the usual manufacturers ...
