The classic fuzz circuit, but now with special extra circuits to give better, clear consistent sound on every occasion. 
Usually Germanium Fuzz's have  problem with inconsistent sound because germanium reacts differently at different temperatures
To fix this issue & provide a better quality fuzz Benson have created a unique temperature control circuit within the pedal - so that now we finally have a fuzz which always produces the same classic fuzz tone - whatever the temperature. 
Also a completely new input buffer circuit protects the fuzz circuit and keeps it consistent and stable, so the Benson Fuzz is not sensitive to other pedals and can be used anywhere on your pedal board.

Finally - the 1st stable reliable classic fuzz sounds - only available with the Benson Germanium Fuzz
