This is a 2012 Carl Martin Plexitone. It has three buttons: OD, higher gain OD and then an independent clean boost. By far the best plexi/hotrodded plexi pedal on the market. I just went back to a trusted old od/distortion pedal and need to sell this one.
They are $250 new - get this one (near new - with box, papers..etc) for $199 obo shipped CONUS. I may entertain a trade (with cash on my end) toward a Fender Blues Jr. amp.
