Dragging up the old Tone Bender thread!
Built a MKI a few years back, and a Supa Fuzz around the same time. The MKI was a real pain, but got there in the end. The Supa Fuzz worked out ok.. but I should have spent more time biasing it. Neither are in my collection any longer so I figured I'd have a go at a MKII.
I'm using Tungsram AC125's.. hfe's are Q1 70, Q2 95, Q3 132. I have a 100k Q2C bias pot and it seems to play nice around 8v on Q3C. Q1 is around 8.5v with the stock 10k Collector and 10k on the base. Q2C is around .3v.
The fuzz is pretty damn musical, I always judge a fuzz by how it makes me play.. if I'm inspired to come up with a new riff or whatever. It happened with this build straight away. I'd just like it if it was a tad sharper.. seems pretty wooly as it stands. Do I mess with the transistors to see if I can tease a little more top end out, or do I reduce the input cap and have at it?
