Schematic is avaiable HERE.
Cool! I used to own this and it was a great do-it-all dirt box. Clean boost to almost fuzz.
Nice!I like the eq design, with the bass being pre-dirt and the treble being post-dirt.Thank you for the layout!
By the way, couldn't the 3 trimmers and the switch be replaced by a single 20K potentiometer?
I guess you can but I'm not sure how useful it will be since the switches toggles between three bias settings.
Tag it! Works just like the original.
Just in case anybody wonders, yes, the treble control is very subtle on the original pedal too.
The 2N3053 isn't really essential either. I just tried with some mil spec 107's at 270 and 289 hfe and it's actually a lot better. still goes from clean to fuzz, but with a lot more presence.
Thanks Ben for the verification and report!
Hi. How do you recommend setting the three trimmers to get as close to the original as possible?
Hi there, If you click on the schematic link above there’s a small section that gives you the values and how to set them. Cheers, Ben.
Thanks. Didn't see the link!
