I'm sorry, I need to revive this thread again.

I need a little help understanding what my guitar does, and why.

In my "new" GR-1SF, I have soldered in one of the orange sprague caps, 223j, mainly just because I found it comfortable to solder on compared to these tiny capacitors that were included. As a comparison, in the single cut build I did before, I have soldered in the tiny green capacitors that were included, these are also marked with 223.

Now, when using the tone pot on the GR-1SF, you can actually hear the tone rolling off and getting darker. On the single cut as a comparison, you can barely even notice it. With a bit of fantasy maybe, but it's by no means as prominent as on the other guitar.

Why is this happening? Do these capacitors really differ that much, or can the pot or capacitor be broken? Any way to troubleshoot it?

Thanks!
