For years we’ve had people send various Big Muff pedals for rehousing into a smaller casing. The circuit board isn’t nearly as large as the casing that it ships in (specifically in the USA reissue) so it’s a great candidate for space savings. Just recently we had a customer request that a Rat be installed inside of the Big Muff to save space. We also installed a Clean Volume knob to each circuit to allow the original signal to be mixed in with the distortion. The end result is two independent distortion circuits in one casing to save space and help simplify a pedalboard.
