All circuitry is faithfully reproduced and fine-tuned from the original EP-3 specifications. The only thing missing are the record and playback heads, with a 24-bit high-fidelity digital delay line taking the place of the tape. All-discrete, through-hole construction with orange drop 225P capacitors, carbon composition resistors, germanium diodes, and other premium parts.
The Catalinbread Belle Epoch Deluxe is regarded as one of the best compact tape echo emulator pedals you can buy. It boasts exact EP-3 circuitry — from the 22-volt power rail to the JFET preamp (later spec), mixer stage, high-gain silicon transistor-based record/playback amplifiers, and the feedback loop.
