Between different transistors with different gains and building and rebuilding I love how heavy it gets and works with my OR15 but the noise always made me scrap it. For whatever reason I never tried a battery in it until recently and wouldn’t you know, the noise is gone. I built a Huminator and now even with a One Spot, no noise. I also just realized that it works just as well behind a buffer too. I got my hands on an OC42 (112 hFe) and a black glass OC42 (245 hFe) and it’s one of the heaviest fuzzes I’ve built. The best part about this fuzz is that it sounds great with lower gain transistors too.

These were my only Ge PNPs i had left. However, could be that i had no B250ks so used a B220k instead. Will buy some others Ge PNPs and buy the appropriate pot and check the difference. May post back soonish with results.Hozy31https://www.blogger.com/profile/16714771534041521767noreply@blogger.comtag:blogger.com,1999:blog-6847048658257278783.post-38043791008486431722015-05-17T12:09:33.648+01:002015-05-17T12:09:33.648+01:00Built it with OC1075 trannys and worked like a cha...Built it with OC1075 trannys and worked like a charm, great sounding Fuzz.

I'm also gonna try out the pedal with a bunch of other power supplies tomorrow at the music shop I work at, see if anything sounds better. I also noticed that my 1 Spot started humming (used to be whisper quiet).Gnarly Headhttps://www.blogger.com/profile/18438393180040329683noreply@blogger.comtag:blogger.com,1999:blog-6847048658257278783.post-43853413692345231442014-07-10T21:55:10.705+01:002014-07-10T21:55:10.705+01:00you might try adding a 10R resistor in series to t...you might try adding a 10R resistor in series to the 9V with a 100uf like this to see if it helps:<br /><br />http://johnkvintageguitars.homestead.com/Effects/Fuzz-ODs/Monolith/9V_filter.pngjohnkhttps://www.blogger.com/profile/00643996045674470081noreply@blogger.comtag:blogger.com,1999:blog-6847048658257278783.post-56535212288150770532014-07-10T21:40:05.063+01:002014-07-10T21:40:05.063+01:00I just built this pedal in a 1590B enclosure.

I used a pair of TK3055 germanium PNPs, measuring around 300hfe each.<br /><br />When I plug the pedal in using my 1 Spot, there is a LOUD annoying hiss. At the lowest output setting, the hiss is unbearable. There's plenty of nice fuzz when I play, but this hiss makes the pedal unusable...<br /><br />Now, seeing as I built it in a 1590B, I had no room to put a battery. But, on a whim, I clipped a battery into the circuit with the bottom off, and voila! No hiss. Just fuzz. Plug the 1 Spot back in, hiss city. I'm gonna wire up a 9V snap to a 2.1mm barrel connector so I can run an external battery for now, but I'd like a more permanent solution and be able to run this off my power supply (I really hate batteries).Gnarly Headhttps://www.blogger.com/profile/18438393180040329683noreply@blogger.comtag:blogger.com,1999:blog-6847048658257278783.post-10497704172994632272014-04-14T18:57:19.143+01:002014-04-14T18:57:19.143+01:00Could someone explain the pot wiring?
