A digital recreation of a Vox AC30, painstakingly designed against the circuits of the best examples of the amp from James Santiago, look him up, he is the ultimate gear geek.

Described as a quantum leap in amp modelling, these are mightily impressive pedals. What attracted me was the way they sounded and reacted to pedals like a real amp, simple controls no faff.

Very good condition, comes with (slightly torn) original box used at home. Worth noting that the stickers underneath have been removed, probably by velcro from a previous owner.
