The Fusion Dynamic Distortion is an adaptation of the Suhr® Riot™ Distortion, originally released in 2009. The Riot is in the family of Marshall-like pedals and is lauded for its high gain “stack of amps” tone.
The updated version of the Fusion is very similar to the legacy PCB, but with the addition of an internal slide switch so that 9V and 18V modes can both be used instead of being hardwired for one or the other.
As in the legacy project, we’ve also brought over the internal Presence trimmer from the Crunch Box. The Riot never had one, though it had two fixed resistors that simulated a 20k trimmer set at around 1:00 (58% rotation). You can always set it to be exactly like the original, but by having the trimmer available, you have access to an expanded range of tones not found in the original Riot.
