I loved this one for getting the IC/Op Amp/ Muff sounds, and more. It has enough gain for heavy playing, and the tone switch helps get scooped, to mid heavy tones. really happy with this build
Build it (it´s a Keeley obsession), and one thing is for shure: Robert Keeley never desapoints me. I suspect he's a kind of Lennon/McCartney of guitar pedals. Well done, Anders. Another one I'll be in debt with you. Cheers!
I guess I’m the carbon resistors guy. But it does sound best with carbons. Built it with a mix and it was slightly harsh. Replaced the blues with carbons and it’s perfect. Thanks Robert Keeley and thanks Fuzzhead. Finally boxed this up with clipping diodes mounted outside the enclosure. Gonna draw a jack-o-lantern with flashing eyes a-la Halloween. Silly fun. Looks cool though.
It looks fascinating and amazing but it has germanium which I avoid. I have no means of testing germanium transistors and I feel like I'm working blind with them.
I wonder if anybody has tried it with a PNP silicon?
Built this a little while ago and found the gain all bunched up near full CW, so definitely going to try a 100KC pot as Ian suggested. Fantastic IC muff style fuzz!!
Great circuit! It's smoother than the IC Big Muff and has better controls. It's great for metal tones (it chugs!) and also both the LEDs light up when clipping the signal which is really cool. When I put it on an enclosure I'll make the LEDs visible

ReplyDeleteI didn't even know about these until today! (and I was going to not build anymore fuzzes!)
ReplyDeleteFoolish mortal, this never ends! Hahahaha seriously though this is the IC muff to build. It’s tops.
ReplyDeleteParts Ordered!
DeleteSounds awesome! I suspect it could benefit from reverse logarithmic on the gain pot.
ReplyDeleteBut sounds beautiful.

...and yours guts looks awesome, Ian. Glad you are liking it!
DeleteThat really means a lot to me! thank you so much. ☺️☺️☺️
DeleteGet ready for some SP riff murdering...

Nice demo and good advice on modding the gain pot with a C100k.
DeleteThank you! The pot arrived today...when I return from work tomorrow I'll fit it and report back 🤜💢🤛
DeleteYes! That's what it wanted!
ReplyDeleteThis thing sounds beautiful!

Oh yeah, It has THAT sound! Have you tried the Psi-Fuzz?
DeleteNo...I'll check it out!

How do I interpret the red box with white?
ReplyDeleteTone knob doesn't seem to do much, is this as expected? Cheers
ReplyDeleteI'd been meaning to dig this one out. The tone control works as expected.
DeleteCheers Tom, will check things over again
