The Shanks 4K was designed to recreate the 60’s Fuzz Face like overdrive boost. Equipped with two vintage germanium transistors. The range of the tone is very wide and has a enough head room to obtain a firm and bright clean tone to an edgy crunchy boost. When turning the FUZZ and the BASS to the highest level will get a thick Fuzz Face like distortion. The Fuzz Color trimmer allows to control the fuzz tone from spitty fuzz to a smooth overdrive fuzz.
