Thank you thank you. Looks like fun.

I haven't been around long enough to know of Fig. But im fascinated to put this circuit on a breadboard. Google didn't turn one up. Could someone point me the right way?

Yes. That is how I did it. Thanks for all the input. I'll grab some parts from mouser.

Roger on that. Thanks. As for the h11f1...I got mine from stompbox parts. Would mouser be a better bet?

Yes I posted the number above. They did not meet your numbers and matched the measurement of the op07s and not too far off from an ne5534 i had within reach. I bought them a year or two ago but i recall them being around $4-5 a piece. I bought 5. I'll sleep just fine though. I ended building...

Okay, big surprise...the lm308s are not real. I am measuring 2.18 mA. That's the same number I got on op07s as well. The h11f1 was measuring from .856v to 5v5. Im not sure what to do with that information but there it is. Pics included. The pcb is from arionfx. So the schematic Im working...

Right, I'll get some pics when I get back to my work bench. I do however have the same fizzle on the pcb and the breadboard (both are in action right now). Im deep into some mods but the problem existed from the very start. What is the test for lm308's? How do I test the h11f1? I've never...

Yes, h11f1 for sure.

OK, this got started over in the mods thread but im moving it over here. As chords and notes decay I hear a lot of fizzle. I'm using an op07cp from Texas Instruments. I have tried lm308. I'm thinking they are real because they came from Jameco, reputable place. Honestly I've tried every op amp...

Another layout plus schematic https://dirtboxlayouts.blogspot.com/2024/02/demeter-fat-control.html?m=1

https://tagboardeffects.blogspot.com/2012/09/demeter-fat-control.html?m=1 I used this in a vibe for a mids control. I haven't looked at the chauffer schem yet to think of where to put it

https://www.reddit.com/r/diypedals/s/eDH9YGMDSv Also here is a corrected layout. The other one isn't wrong but I think I spelled it put a little clearer. https://ibb.co/mFc2MKHY Right now I am doing a Frankenstien set of mods to an expandora. Everyone one is a new set of headscratchers. 😀

I only did the bass mod. However the problem is proving to be intermittent now so that says something is up. I put an lm308 in and still intermittent too so the search continues for now. Thanks.

In case anyone wants to talk about this circuit some more....what's with all the fizziness? You know, that background op amp crackle. Especially as notes/chords decay. I've tried different options (lm741, 5534, different brand op07s, etc). What adjustments can I make? I am however loving that...
