    2. Yes it will work. But a more simple sollution would be to use normal power with 2N5088 transistors. If doing so, you have to flip around all electrolyctic capacitors and D5.

    3. That’s is better I think . So the q1-q4 are 2n5088 . the Schottky diode flip and the el. Caps .. but the sound is the same or out of big muff?

    4. Yes, it should sound the same since 2N5088's is NPN analouges to 2N5087.

  3. I flipped the polarity and used 5088’s. If you do, don’t forget to also flip the power protection diode. The PNP version sounded a bit fizzy. NPN sounds pretty good. Thanks
