Whilst here to film another item, Gaz Williams - regular contributor to Sonicstate and  guest on our Sonic TALK podcast brought his recently acquired Abyss - the four voice poly synth from Greek manufacturer Dreadbox-FX.  Gaz has been hankering after one of these for some time, so was delighted to be able to show us around his new synth.

Its an informal journey around some of the Abyss features and sounds. We do hope to get hold of one for  review at some point in the future.
