The single-channel Carl Martin PlexiTone was designed in association with Pete Thorn, and is housed in a small pedalboard-friendly housing with three knobs and one switch. Apart from Thorn's slight modifications that give this new pedal a tighter bottom end and slightly softer high frequencies, it is exactly the same gain structure as the High Gain setting on the original Pro-Series PlexiTone. It just plays better with different amps.

The single Plexi also incorporates the new DC-DC converter circuitry, so the pedal can be powered by a regulated 9V power supply, but will still operate on the same +-12V level as the original AC powered PlexiTone. This allows Carl Martin to use the same high-quality components, which provide the same tone and headroom that make the CM Pro-Series stand out from the rest.
