I do realize this thread is a Bit old, but still have a few comments on the MP1 box.
Haven't had a chance to try it myself, but clips sounds pretty pretty.
Still, IMHO, ADA Amps missed some needed features:
They didn't add a stomp option to switch from clean to distortion, which I see as a bummer.
Further, they should've added rear jack allowing to do this channel switching from remote, like via one of the many [MIDI-based] stomp controllers.
Matter of fact, they should've added stomp switches to allow switching between clean and two different distortions, at least like a boost option for solos, which could easily be done even with only a single set of EQ controls.
And I fail to see why on earth they didn't include the classic compressor, as this is a fairly low expense, component-wise.
And methinks it's too expensive.. Apart from these musings, I have absolutely nothing against this concept box.
