The circuit is a microphone amplifier for use with low impedance (~200 ohm) microphones. Getting Started with OrCAD 9. Those are nice and traditional silicon Fuzz Face style pedals, but the Vertex BC109 Fuzz is much different. The wah circuit basically sprang from the 3-position midrange voicing function used on the Vox Super Beatle amplifier. Stevie used two Vibroverbs together, during a long stretch of his career. The collector of transistor T1 is connected to the base of transistor T2, while the collector of transistor T2 is connected to relay RL1. They are suitable for use in driver stages, low noise input stages and signal processing circuits of television receivers. The Vertex BC109 Fuzz can achieve various shades of boost, overdrive, high gain, and full out fuzz tones with the manipulation of the volume control, and I've never been able to get that amount of variety out of a fuzz while still keeping my pedal controls. In small, discrete quantities, transistors can be used to create simple electronic switches, digital logic, and signal amplifying circuits. Incidentally, we can substitute a 2N2222A, 2N4401 or any general purpose NPN with a minimum hfe of 50 for the 2N3904 transistor used in this design example.
