Re: Fuzz Factory NPN AC127 - PCB n Layout Inside

The schematic is down and having read through the discussion it seems it wasn't updated when the corrections were made. Can anyone upload a correct schematic or simply explain how to build an all-NPN negative ground Fuzz Factory? If you want it to oscillate, you shouldn't do all NPN. As Scruffie st...

Probably explains why the thing is so expensive.

Re: Frantone Hi-Ball [Lame Alert] [traced]

The diode compensation is legit. I've thought of ways to manage that and avoid LEDs always sounding best just because they're louder but this is a very elegant situation. It sounded totally right-on to me. Best thing about this design, IMO, and what prompted me to post it after forgetting about it ...

Looks like someone beat me to it, a long time ago... :lol: Kadent_Treblefuzz_v1_AG.gif But didn't start a thread! :evil: I see a mistake I made with my trace, having the 4k7 going to ground instead of back to Q1's base... was kinda wondering if that would've worked correctly.

Re: Frantone Hi-Ball [Lame Alert] [traced]

I mean, I understand the idea of using maybe an "abnormal" input impedance to get a certain tone. I can accept that kind of thing if the end result sounds good. But this pedal didn't sound good to me at all, so it really made me wonder why this choice was made. I welcome people to please try this ou...

Re: Germanium Overdrive

Good job thinking of the stacking different fx together thing. Rangemaster+Fuzz Face is what inspired my Shizzle fuzz back in 2007. Cheers, Shizzle sounds cool. I've stacked a rangemaster & fuzzface, reminded me of a tonebender a little bit. Tonebender mk2 is very similar concept; fuzz face style f...

Re: PNP Ge Rangemaster debugging :)

Kind of weird as I saw plenty od PNP Ge Rangemaster's clones with both DC jack and battery clip and they didn't have any charge pumps etc. Any ideas? You can realize negative ground with a PNP Rangemaster (or any other PNP circuit, like a fuzz) by reversing the circuit so it looks "upside down" in ...

Re: DMB Lexi pedal, gated fuzz!?!?!

Seeing over 7v on the Drains of a couple of the JFETs makes me think the bias is off on those. But that wouldn't be the case if they were used as buffers in the circuit. It's hard for me to tell what does what from the photos. Someone needs to trace it out. Just based on guessing, I would try adjust...

Re: Analogguru - FET-Booster

I just built a variation of this using a 2SK880 FET. It sounds fantastic. The circuit isn't exactly the same; a few changes here and there. Instead of the gain control, the 10uF cap is fixed across the Source resistance so it's high gain and I used a 100K audio taper pot after the output capacitor a...

Also a slight chance the JFETs in the opamp got zapped, which can make them turn hissy
