Carl Martin AC Tone, Dual Channel version. It‘s in perfect working condition, and great cosmetic condition, with the only blemish being the foam pad underneath the pedal does have some usage scuffs, as pictured. The pictures will show it, but this is the newer version that doesn’t have a built in AC adapter, so it runs on a standard 9V power supply, like most pedals on the market. Just purging some pedals. Don’t hesitate to ask any questions!
