Pink Effects Fuzz - Pink Tuxedo

A note from Pink Electronix:

With circuitry based on the classic Fuzz Face, the Pink Fuzz uses NPN silicon transistors rather than PNP germanium transistors. The transistor connections to the PCB are socketed for easy swapping to allow you to experiment with different settings and create custom fuzz tones. Powered by a 9v battery, the input jack serves as the on/off switch, so just unplug to kill power. This model includes an external bias control for easy access to shaping different fuzz tones rather than having to remove the bottom plate to adjust the trim pot.
