im putting kent armstrong distortion(neck) and ultra distortion(bridge) pickups im my schecter xxx and was wondering if its worth replacing my volume and tone pots. and if i do is it worth it to go from 500k to 1meg volume pots
If you're playing the kind of music where KA distortion and ultra distortion pickups are your pickup of choice, you will see little to no tonal impact by changing the pots.

Maybe if you were some kind of ultra clean Jazz player or something.. but no, man. I say the stock pots will suit you just fine.
