Wasp was a quirky little synthesizer that, despite its toyish
look was quite capable of funky analog types of sounds.
Under the hood the Wasp was a real surprise! It was actually
a very early DIGITAL synth that also happens to sound great!
With ANALOG filters, envelopes and controls, the Wasp offered
flexible and traditional synthesis of cool bass,
and other useful monophonic sounds.
It was used by 808 State, Dave Holmes, Vince Clarke, WhiteHouse
and Add N to (X).
It's designer, Chris Hugget, also designed the Oxford Synthesizer
Company's OSCar Synthesizer.
