Hey all, I installed a JB in the bridge of my G&L Comanche that is wired exactly like the S-500. I noticed that the JB sounds extremely dark and muddy. How's that for unexpected? I was wondering if some of the kind folks here could take a look at the PDF schematic and see if anything might be suspect. I'm wondering myself about what the C3 cap does. Here's the schematic: http://www.glguitars.com/schematics/S-500_schematic_blockdiagram.pdf Thanks!
