Drawing inspiration from its germanium predecessor, the Fuzz Phrase Si encapsulates the rich harmonic profile and dynamic response of the esteemed Fuzz Phrase Ltd. It strikes a perfect balance between sought-after tonal characteristics, long sustain across the register and "clean-ability" rivalling the best vintage germanium fuzz circuits.After the meticulous testing of various silicon transistors, the BC107s emerged as the unequivocal choice. We then proceeded to fine tune elements of the circuit specifically to these transistors seamlessly embodying all the attributes synonymous with the Fuzz Phrase legacy.
