I revamped Roger Mayer's Axis Fuzz and stuck on a phase stage to make the circuit sound like a tube amp. You probably notice the Dallas-Arbiter Fuzz Face biasing configuration. You can use a regular low-pass RC network, ala the ProCo Rat, to make the circuit sound like a "open" tube amp. This fuzz sounds ALOT like the "Modern Lead" amp model on my Zoom GM-200. You'll be surprised at how much this circuit sounds like a tube amp.
Hi! What about hfe of both transistors:it have to be equal or differ must be?
ReplyDeleteI don't think you have to match them, especially since one is NPN and the other is PNP.
Deleteis not in the image transfer library?
ReplyDeleteSorry about that. It's in the Misc. folder now
DeleteVerified. Sound amazing. 1N34 instead 5817. Thank you.
ReplyDeleteThat diode is for power polarity protection and won't affect the tone at all. A germanium isn't great for that. Swap it for a 4001 or similar rectifier diode if you don't have any schotky diodes available.
DeleteAnd thanks for verifying!
DeleteI wasn't sure what kind of diode I got and put this on. Usually 4001 or similar is my choice. Thanks again for your work
ReplyDeleteNice Fuzz. I used Q1 2n2222,Q2 2n3906, Good soud & gain. Tried Q2 Ge PNP Hfe from 35 to 90 (hfe without difference), good sound. Tried Q1 & Q2 Ge, very good, but i took pot on in to decrease gain!So, thanks, David!
