“Two pedals in one, on the left, the Soda Meiser and the right is the Vintage Fuzz Master. The
switches control the vintage fuzz tremolo mode and chaos mode. With
both pedals on and both modes running, this thing is “over-the-top” chaos. I like to push a tube amp rhythm channel to the point of break up, then run both sides of the pedal together. You get a gnarly chainsaw tone out of it, and if
you have some extra low end on your amp, even more savagery!”
