Player's Gear Fuzz--Packer's Tar Soap TinHand wired in the USA in our little shop in rural Indiana. Ideal as a secret weapon in the studio! Control set is simple: one on off switch by the input jack. This is a meaty fuzz gritty square wave goodness with a smidge of a volume boost for those moments that require maximum thickness. The pedal works great with either a clean or crunchy amp. Running into an amp that is already overdriving a bit creates a smoother effect. Uses one 9v battery.
