Discontinued #181 JHS Firefly in excellent condition. Pretty much flawless, but no box or manual. This is a fantastic fuzz for those that love those classic fuzz tones. Serves as a modern, upgraded tribute to the late-1960s Sola Sound Tone Bender MKIII.

Key Features & Controls:

• Three Germanium Transistors: Uses hand-matched NOS (New Old Stock) AC128 transistors for authentic vintage warmth and touch sensitivity. 
• Four Interactive Knobs: Features Volume, EQ (functions as a treble cut/fattening control), Fuzz (gain amount), and Bias.
• External Bias Control: Fine-tunes the voltage sent to the transistors, letting you compensate for temperature changes or dial in gated, sputtery, and heavily saturated tones. 
• Power: Runs on a standard 9V DC negative center power supply (consuming under 100mA) with internal voltage and polarity adjustments.
