Royal Albert Hall Bender

Happy Fuzz Friday everyone! Got a request for this one put forth on FSB. It's based on the ThroBak sTone Bender, which itself is just a straight clone of the Tone Bender Mk II Professional. The layout is setup for positive ground and PNP transistors. You can use a voltage inverter daughter board or flip any polarized components and use NPN transistors if you want to daisy chain this with other effects. Also, I added a 1k limiting resistor of the bias pot (far upper right side of the board) that may need to be adjusted to taste. Easy fit in a 1590B.

  3. Verified. NpN version with MP35 Russian Germanium transistors and 390 Ohm resistor instead 1K (but i try other value later). Thank you again.

  4. first cascade made darlington like animato: npn+pnp mp38a + mp 42b, bias resistor should change.very cool sustain.

  5. Anyone got problems with low output volume. How can you increase it?
