5 from 5 Great vintage fuzz

This is an easy build that gives great vintage fuzz sounds. Sounds very similar to a Mk2 Tonebender so itll give those late 60s sounds a la Beck, Page etc.

5 from 5 Built an excellent fuzz pedal with only a few changes

The schematic and bom by GuitarPCB is close to the original (modified big muff schematic, with removed clipping diodes, and added coupling capacitor), but there are a few differences from the schematics I found in several places in the internet, mainly: I found no schematic using the D5 and D6 diodes (???), no schematic using germanium clipping diodes (but silicon ones), and no schematic including the C15 electrolytic capacitor. I so removed D5 and D6, changed D1 and D2 to silicon 1n4148 as seen in the internet. C15 was already soldered and I didnt made the effort to remove it for now. You can find schematics using different values of resistors here and there, but the values used by GuitarPCB at least look OK. Compared to the GuitarPCB BOM , the main change is germanium diodes vs silicon (BTW GuitasrPCB says silicon diodes can be used too). The sound with silicon diodes looks a bit more defined to my ears, the fuzz gain is more manageable, but it looks like the output level is more comfortable with silicon diodes, unity gain is reached at 12 oclock and can be increased more after that, where germanium diodes require to run full gain. Other than this, a great pedal, better than the (modern EHX) big muff I was able to try until now. Notice that Im using a low wattage tube amp at home.
