TightFuzz was requested by Amptweaker™ players, and this one will certainly add some vintage tone to their arsenal. While most vintage fuzz boxes have very few controls, the TightFuzz includes a Tone control to tame the fuzzy edges and the Tight control, a mainstay of Amptweaker pedals, which varies the pick attack from smooth and thick to tight and aggressive. This is particularly helpful for tweaking a fuzz tone, since many tend to be too flubby on the lowend. While many modern fuzz boxes have chosen to create wacky over-the-top fuzztone, the Amptweaker approach is to make something that has a lot of flexibile but usable tones. The most requested feature was the Germanium/Silicon switch, which changes the output stage from a softer, lower gain Germanium to a heavier, high gain Silicon transistor. This cool pedal also has the ability to get lower gain tones easily, with an Auto Bias that adjusts appropriately with the Fuzz control, to get the cleanest and nastiest distortions possible with one control. It also has an Edge switch with a Smooth setting to further knock the edge off, and a 60's/70's switch that transforms the pedal from tighter, lower gain 60's tones to fatter and heavier 70's tones. One of the important differences between the TightFuzz and most 'reissue' fuzz boxes is that with the addition of the Tight control in front of the fuzz circuit, the input of the fuzz circuit is effectively buffered from the guitar....but in a compensated way.
