Had a look again tonight. I cleaned up the 370p arrangement. That got rid of the fuzz and the plexi sounds good now. It has a lot of gain! That surprised me. I will build it up on a vero board after all. It is like a gainier version on the love pedal jtm Pb

I bread boarded the 800 version that @swyse posted tonight. I find it has a sharp buzz sound on attack. One thing i was not sure about is if pin 8 goes to ground with 4 or only pin 4 to grd. If i ground pin 8 as well there is no output. So i think that is a mistake in the schematic Maybe i...

Ya, that is what I thought, but I haven't seen a schematic that had two at the power supply like that. So, I wondered if one was not labeled correctly...

Thanks for posting that. I plan to order some parts to try this out. Is there a good alternative to the bav70? My local shop nextgenguitars.ca doesn't have them. Usually I see 1n5817 at D2. Is that an LED at D1? thanks Pb

great. I was planning to bread board it to see if I should build both :-) thanks Pb

Ha ya i am starting to see how deep the rabbit hole is 😂. I well add it to my list! Thanks Pb Pb

Looks great. I think I need to build a phaser. The closest I have is an mxr vibe. The enclosure looks long, is it a 125b? Or is it just the photo angle? Pb

does anyone have trouble with the m800 keeping its bias? I dial it in and a few days later it is dull or bad fuzzy sound. Is this a j201 issue? Is there a way to test them? I have extra if i have to replace them Thanks Pb

Great thanks! Pb

Hi all, I have a few questions about the charge pump board. I think this would be great for my PNP fuzz pedal design to take in 9v centre neg power like the others. in 2 holes on left and out 2 holes on the right: these look like input/output wires, maybe there are 2 for stereo? There is a + -...

Thanks for the confirmation! Pb

I notices the two holes beside the + - are not labeled on the pcb. I am assuming they are GND? thanks Pb

I don’t mind electrolytic but i haven’t heard tants or mlcc. My usual part shop doesn’t sell them Nextgenguitars. I will have to try them sometime Pb

Interesting. I note that pedalpcb design asks for a 10u mlcc which i had to google. That looks like ceramic. You prefer a tantalum over ceramic as well? Thanks Pb

Ok. That makes sense with the arrow off to the side. Some schematics put the arrow in the middle. Hopefully when it matters there will be labeled pins Thanks Pb

Thanks Pb

Looking at a buffer schematic, the G is in yellow below. But I am assuming that the drain and source are interchangeable since they are not labeled. While I am at it, can a electrolytic be used in C2 (neg towards out)? thanks Pb

Wow that is interesting. I ended up ordering from amplified parts. https://www.amplifiedparts.com/products/diode-1n34a-germanium He has some 1n34a i hope they are legit. I ordered extra to compare. Hope there are at least 2 suitable. Now i just have to get some red flocking material to cover...

Thanks. I will order some extra to compare Pb

Sounds good. I have some snap off sockets i can use. Thanks Pb
