Dunlop Band of Gypsys Fuzz Face

Here's the Band of Gypsys Fuzz Face from Dunlop for Fuzz Friday. Despite being called a Fuzz Face, the actual circuitry of the Band of Gypsys version isn't even close to the original Fuzz Face. It's pretty close to an Octavia without the transformer. Here's the schematic for reference.

    1. 550 es NPN, el esquema muestra un PNP. 558 está bien.

  2. Most excellent! i was planning on reworking my octavia today for a better fuzz tone but i'll skip it and make this if i have any perf.

    - estaban, the transistor in that position has to be a pnp like a 2n5087 or 2n4402

    2. i'll try to make a video. i have to either put different transistors for the npn's or bias it a bit more because it is slightly gated

  4. Built. I did not expect such high gain, thank you. You were following the FSB thread? It's certainly not a Fuzz face and I love the sound.

  6. I use a BC550 and 2 MPSA18, But I have problems with the fuzz potentiometer, at min and max sound the same :/.

    1. Kinda doubt this is why your fuzz pot isn't working, but the BC550 is an NPN transistor and Q1 is supposed to be a PNP... You could have a bad pot or have a short somewhere in that area.

    2. Thanks a lot, I replaced the BC550 for 2n3906 and now it sounds really well

  8. Great layout! The sound is very high, even with the volume close to the minimum, I tried several transitors, but the combination of BC558 or 2N3906 plus the MPSA18 for me is the best, now I'm testing with BC558 and BC109C, and the sound is more open, also not bad at all.
