Transponder Delay Roller

Classic Audio Effects was known for their innovative roller-based pedal designs that replaced traditional rocker mechanisms with a rotating barrel system. Their unique approach to expression control earned a devoted following before the company ceased operations.

The Transponder Delay Roller combines a delay effect with Classic Audio's signature roller control, enabling hands-free real-time adjustment of delay parameters during performance. This integrated approach eliminates the need for a separate expression pedal.

The roller mechanism uses the reinforced kevlar drive belt and sealed bearing system featured across Classic Audio's product line. The 270-degree rotation range provides smooth, precise control, while the positional LED indicates current setting.

The integrated design is significantly more space-efficient than using a separate delay pedal and expression controller, making it ideal for compact pedalboard setups.
