Jeorge Tripps, the sensei of delay equipped this Puss with six growling bucket brigade chips for up to 900 ms of pure analog delay, an LFO modulation circuit and tap tempo switch to program in up to three full seconds of real time delay for ethereal ambiance. Loaded with controls, you can dial in anything up to maximum freak out effects. For even further tweakability, Tripps even added a wet/dry mix control. An expression pedal socket provides continuous real time control. True hardwire relay bypass. Powered by 9 volt battery or AC adaptor (ECB003).
