VFE Pedals Fuzz Duo

A great (soon to be discontinued) fuzz by VFE Pedals.
You can find more info on their website here and schematic on their FB page.


  1. Sounds pretty interesting. Could another taper be used instead of the W1m pot? I also noticed that you labeled the transistors backwards in the layout notes. Not to nitpick or anything. I may have to give this a shot.

  2. Hi Jim.
    It's been corrected.
    If you check some of the other VFE layouts comments, Peter Rutter (from VFE) has suggested how to substitute W pots. The problem is that they were custom made.

  3. This one reminds me to my plum crazy efx "polecat fuzz".
    It was basically a "fuzzy lady", (kind of a fuzzface clone), with a switch that combined ge-ge/si-ge transistors.

  4. Verified! This is a really nice fuzz with some nice fuzz options. Used Bc108s with hfe ~550 and OC139s with both hfes at 105. Thanks Alex & VFE for the schemo.

  5. This is gorgeous -- it may be exactly the fuzz I've always wanted. I used AC176Ks for the Ge transistors; got them from this eBay seller, who I highly recommend:

    If anyone's struggling with the switch numbering as I did, this is the scheme to use:
