This is an exceptional pedal, no doubt. These are handmade by one Mr. Sugano, and this is the second and more compact version of the idea. It's a Plexi/JMP in a box, as you've likely guessed from the aesthetic. The channels always run simultaneously, so you can dial in the thickness on the 'normal' channel and the snappy chirpiness on the 'high treble' channel. There's a bass cut control on the little knob to help it to play nice as switchable dirtbox. But... you're going to want to leave it turned on, because it sounds unreasonably good.
