i finally got around to playing the pedal tonight, through my 18 watter. it sounded awesome with the sg, great 60s/70s vibe. this is their "plexi" in a box. i wouldn't it sounded exactly like a plexi marshall, but close enough for rock and roll. i had it set to the warm setting, which decreases the output, it wasn't a problem though cause i just turned up the volume knob. this is a one knob pedal, the distortion level is preset, and you just adjust the output. nice and chunky on the warm setting fo sho. chucky likey!
