For my 2001 & 2003 made in S. Korea I'm replacing both original EMG HZ 40's pups & preamp with Seymour Duncan Blackouts ASB-BO-5a & Seymour Duncan preamp STC-2S-BO. The preamp includes the bass & treble pots. I'm looking for recommendations on replacing the remaining balance & volume pots & capacitor. All Seymour Duncan would tell me is to use 250k vol. & bal. pots & .022u capacitor. What brand(s) will fit and go well with my new pups & preamps? I see there are different volt ratings for capacitors. Thanks!
