GFI System are renowned for their digital time-based pedals, most notably the powerful Specular Reverb and Clockwork Delay. The Synesthesia, however, represents GFI System's first foray into the world of modulation.

With a flexible dual-channel design allowing you to use two effects simultaneously in parallel (Mixtures), series (Cascade) or stereo (LR-Split), you can of course use any of the GFI System Synesthesia 30 algorithms as standalone effects too.

With MIDI connectivity, 32 preset slots and other powerful modern features; the GFI System Synesthesia does more than simply embellish your core amp tones!

Up to 30 on-board algorithms - more will be made accessible via the 'SymmLab' editor.
