Question about nodding pedals by changing pot values

Re: Question about nodding pedals by changing pot values

So unfortunately all I had was a pack of 22k resistors. I tried one and it works exactly as promised! However, it is too much of a good thing. I am going to buy an assortment pack and try a 100k. If that's not ideal maybe a 47k will be goldilocks for me.

One last question: it seems to have the same effect when bridging the left tab and the middle vs the outer two tabs. Does it matter which way I install it?

Nope, it doesn’t make a difference.
If a 22 is too much, which I read makes it dimmer, 100 would make it even more so. Try wiring 2 of the 22s in parallel, that will equate them to an 11k.

He means it removes too much gain I think, in which case moving towards a higher value will be better.

That's a pretty simple circuit. Why not buy all the components for 20-30$ and then breadboard it? You can plug various values in until you've found exactly what you like, then throw it in a case and sell the old one.

Might do that someday, but right now I don't have the time to get that involved.
My pattern is to modify things a little, then a lot, then build from scratch. Did it with cars & guitars, now I'm on pedals.

Yes, 22k dropped the gain too much.

Re: Question about nodding pedals by changing pot values

Mission accomplished!
Added a 100k resistor to the gain pot. Still goes into "way too much gain" territory but the range between no gain and light gain is now between 7 o'clock and 9, rather than 7 and 7:15. MUCH easier to dial in what I consider the sweet spot.

Thank you everyone.

You built a car from scratch? I'm impressed

It's an expression - I completely modified a 1953 Chevy from top (chopped) to bottom (suspension swap) & everything in between. We call that "building a kustom." Although my next project *was* going to be a literally built-from-scratch roadster...I had children instead.
