South Carolina's Classic Audio Effects brought a few new pedals to NAMM. But two of them, the Yukon Digital Room Reverb and the Transponder Digital Delay (pictured here) are built around this cool expression wheel, which controls delay time on the Transponder. The wheels are smooth and feel robust. And though fine tuning a delay time with your toe might not be the easiest task, the pedal is awesome for extreme delay time shifts and accomplishes what treadle-based expression pedals can do in a small enclosure. Both the Transponder and the Yukon will sell for $199.
