Description

The exact transistors Bonamassa chose for a full sounding and articulate Fuzz face! (The hFE ranges have been carefully matched for this circuit.)

Limited Supply! –  No Purchasing Limits. Each set will have measurements printed on the bags. I personally spent weeks hand sorting these for the “Perfect Matches” for your Bonamassa Style circuit.

All transistors tested for gain and leakage using a Pro Atlas DCA55 test unit. A Russian MP39B: GE PNP with hFE (30-50) is used in the Bonamassa Fuzz at Q1 position. The Russian GT308V (ГТ308В): GE PNP (Note: A Cyrillic В is equal to Latin V) have an hFE (50-80) and is used in the Bonamassa Fuzz at Q2 position. Leakage has checked out excellent with many at 0.00 and none sold with readings above 0.20

Disclosure: As with any transistor be 100% certain of the pin out before placing it in circuit with power connected.

  • Q1 – MP39B with hFE (25-50)
  • Q2 – GT308V (ГТ308В) with hFE (50-85)

Be sure to verify the pin out against the circuit board.

Video Demo below shows low hFE transistors in operation.

This set is very comparable tonally and is what’s used in the Dunlop Pedal:
