Hey guys. I've got a '07 Gibson Satin Finish ES-335 with the original, stock, '57 Classic humbuckers. I've been strongly considering getting P-90 type single coil pickups in there. I don't dislike these humbuckers per se, I just really prefer clarity and punch over sustain and compression. However, I've read that I should upgrade the volume pots from 250k to 500k. I assumed they were already 500k, but after emailing the guys at Gibson, they assured me that they were indeed 250k. Will this upgrade have a noticeable affect on my tone and responsiveness? Also... What value caps do I need to look out for?
