I had an old no-led Rat 2 back in the early 90s. I sold it at some point when I thought the filter knob was no longer working. Kicking myself years later as it would have been an easy fix! Would be curious to see the innards of a recent one too.
Thank you! I took a look at Jason's Ubu Roi schem and could see the difference right away, very similar to what you mentioned as the moreideal configuration. He's got me covered but I'll probably try this fix at some point for fun and to potentially sell the GOAT off.
I did a BB-type build recently and am getting some intermittent footswitch pop, even though I used an opto bypass that should prevent that. Checking for voltage at the circuit in and out, I see that there is voltage on the output going from 0v up to just over 1mv. It sort of builds up slowly and...
Nice! All but one of my TB builds have just been wired as positive ground but of course are battery-only. Did not know there was a way to daisy chain without a charge pump. I did a PNP Fuzz Face recently and I'm pretty sure the charge pump is introducing noise and even causing some odd behavior...
That was a dual-channel preamp using FETs and Ge diodes. The FET needed for it went extinct so it was a short-lived offering. You could probably still find posts about it on the Madbean forum from around 2016-17. I know it probably inspired some of jubal81's offerings as Bolt and Forge.
Thank you! I realized I am getting some intermittent footswitch pop on this even though I used an opto-bypass setup, lol...I'm suspecting a dodgy electro leaking DC, but can live with it until I get a chance to swap 'em out.
This is a modded Bluesbreaker-type board that jubal81 gave me years ago. I've not had much motivation to build overdrives since his Cascadia is so awesome, but I was having some nostalgia for the now-defunct Grind Customs when digging through my PCB stash, and I also hadn't really tried anything...
Nice! This is on my eventual build list too. I've done a Standard Fuzz and a Kay Fuzz with a bunch of mods Mark Hammer came up with. They're both great but I have to do them all...that's a helpful point about the noise floor.
Great build! I think I remember seeing that this circuit has some resemblance to the Keeley Fuzz Head, which I've build more than once and like a lot. I would like to go to Australia again as well. Can't move for the amazing bird life! Those shifty Ibis do like to come try and steal your food in...
Seriously love the design! This is one of my favorites fuzzes too; it also happens to be one of my favorites overdrive/distortion circuits. Yes it can do that much!
