the only resistor you can't see is R14 I did verify that it is a 220K with the colors red, red, black, black, brown
I hope these picture work if not let me know what you need
Thanks
Glenn

You should put R5 and R6 back they way they are supposed to be stock.

Are you certain you don't have R4 and R14 mixed up. It's hard to tell from the pics.

You may have a short underneath the reverb module. You can desolder it. Or you can use the continuity test function on your meter to see if there's anything making contact that shouldn't be. For example, is R10 connecting to R11 in anyway? This could create a feedback loop.

I assume you meant 220R. A 220K would be red-red-black-orange-brown.

R5 and R6 are the only components that are modified at this point I will put them back to stock with their 4k7 resistors. Right now R5 has a 100 k resistor in its place because it was the only thing that would stop the oscillating and I just left our 6 out. Like I said above I will put R5 and R6 back two stock and check the whole circuit board including the Reverb module for shorts and then I will get back to you

In one of the picturese R14 is being hidden by C4. I'm pretty sure R14 is a 220R resistor.

Okay guys got to update. I put resistors R5 and R6 back to their original resistance 4K7. Then I checked the whole pedal for shorts everything checked out okay but I did notice a buildup of solder flux around where the switch wires go into the circuit board. I thought I had cleaned it all off prior to assembly but I guess I missed the switch wires. I put the pedal back together and played my guitar through it for about a half hour and it seems to be working fine now no isolation, I love this thing it's nice, thanks. Now I'm going to give it a nice paint job. Should I be using solder without flux in it because solder flux seems to be a big problem. I had the same problem with my mouse pedal when I first put it together it wouldn't work at all so I clean the solder flux off the back of the circuit board and it worked fine after that. Thanks again for all your help and quick responses.

What brand of solder did you use?

It's called Kester Industrial 50/50 is the core and the flux is nosput. That's all it says on the spool

This was never an issue until recently...at least not that I've noticed. It seems like within the last year or so, this problem is happening more frequently now. I ask because I want to make note of the brand of solder used to see if there's a correlation.

I just have to remember to be more thorough when I clean the flux off the circuit board. I use 50% water and 50% isopropyl alcohol to clean the flux off the circuit board. Thanks for all your help I appreciate you guys and your quick and knowledgeable responses.
