EDP Wasp Deluxe (1979–1981)
A rare British analog synthesizer with a full-size keyboard, built as an enhanced version of the original Wasp
Overview
The EDP Wasp Deluxe is a monophonic analog synthesizer from Electronic Dream Plant (EDP), designed by Chris Huggett. It was made from 1979 to 1981 as an upgrade of the original Wasp. The touch-sensitive interface is gone, replaced by a more playable 37-key full-size keyboard. Only around 50 units were made - no more than 100 according to EDP - so it is exceptionally rare. The case is wood. The core circuit is the same as the original, down to matching component designators, but the Deluxe adds an oscillator mixer and an external audio input.

Design
The Wasp Deluxe swaps the original's touch keyboard for a conventional 37-key synth-action keyboard. It adds an oscillator mixer and an external audio input, and keeps the original Wasp's circuit layout with identical component designators (IC1, C1, R100, etc.). The PCB is mounted to the front panel via the rotary switches. Over time they can split and fail under the weight of the board. Replacement Alpha Taiwan rotary switches are identical and widely available. The synth has two audio oscillators and a noise source, routed through a filter. A control oscillator affects both audio oscillators.
Context
The Wasp Deluxe was a direct enhancement of the original EDP Wasp, which launched in 1978 at £199. With fewer than 100 units produced, it was a limited-run upgrade aimed at better usability and reliability. It was the high end of EDP's early analog synth offerings, though no details place it within a broader product lineup.
Market
Wasp Deluxe prices keep climbing, with decent units selling for £600 and up on eBay. Common problems are failed OTA chips in the VCF due to overcurrent, damage from amateur modifications (such as attempted CV control additions), and cracked rotary switches from carrying the PCB's weight. The service manual is available online.
