For Sale: Jasper Synth – EDP Wasp Clone + desktop stand

(Last Updated On: 15/10/2019)

I finished another Jasper Synth (EDP WASP clone). For this Jasper I’m using a slightly re-designed 3D printed case which fits into a desktop stand. For the first time I’m using PETG instead of PLA for the case. PETG is a bit more flexible and not as brittle like PLA printed items. (link: PLA vs PETG) The Japser comes with MIDI IN and OUT and the switch for 2 different “hold” functions.

The Jasper enclosure is 3D printed (glued together) and consists out of the Jasper enclosure and a desktop stand with a wooden element. The Jasper is ready and fully functional but I’m currently waiting for a shipment of screws to finalise the assembly of the casing. The wood on the photo will get a finish with hard oil wax.

Jasper Synth

The Jasper Synth is a clone of the EDP Wasp synthesizer that was made by the small British company EDP (Electronic Dream Plant) for a few years from 1978 to 1982. Credits to Jason from jaspersynth.co.uk.

The Wasp was one of the first commercially available digital/analogue hybrid synthesizers. Designed by Chris Huggett and Adrian Wagner who created it as an affordable synthesizer using the then newly and widely available inexpensive CMOS digital logic chips.

Case

3D printed with PETG Prusament black.

Demo

I uploaded a demo of the synthesiser on youtube. It’s exactly the offered synthesizer but the video is showing a pre-version of the final casing.
