The Belle Epoch Deluxe honors the EP-3 lineage by faithfully reproducing the original EP-3 specifications part for part – the only things missing are the record and playback heads – with a 24-bit high-fidelity digital delay line taking the place of the tape cartridge. Exact circuitry reproduction of the 22v power rail (running off a standard 9vDC power supply) helps to achieve that expansive plugged-into-the-wall sound. The JFET preamp (later EP-3 spec), mixer stage, and high gain silicon transistor-based record and playback amplifiers and feedback loop lends to the big, warm feel expected from these legendary musical devices.
