Inside, we find a pair of the eponymous BC-108C silicon transistors, and a much simpler circuit board than the Sugar Drive’s – with fuzzes, simplicity is king. Now there are just two controls, for output level and fuzz, plus a buffer switch – not for bypass this time, but for the fuzz circuit itself. True bypass means that when the pedal is off, with no processing or colouring going on, the signal from your guitar passes through all clean via a separate path outside the circuit. This means that a true bypass pedal in it self won’t alter your tone but the fact that it doesn’t do anything to drive the signal (when it’s ... Refractor Overdrive Klon Centaur Professional Overdrive Overview Controls & Usage Standard overdrive controls on this one. • Treble control allows for EQ adjustment of the top end. • Output is the overall effect volume. • Gain simultaneously increases the gain and blends from clean signal to dirty using a dual pot. Modifications ...

First of all, the feed-forward networks - since there's no buffer in either of these, will these not also act as feedback? Positive feedback, at that? No, because of the input buffer. The output impedance of the input buffer can be considered 0 ohms, so the voltage at that point of the circuit is 100% from the input. Wampler Tumnus Classic Overdrive Pedal Tumnus is a versatile addition to any setup, any style. Stack it with another pedal to help push or shape the total amount of gain, use it as a stand-alone overdrive, or use it as a slightly dirty boost to push the front end of your amp over the edge.
