I bought a used 08 VM Jazz and I will start off by saying I love the tone! It is killer. It needs to be sheilded for sure typical grounding hum/sheilding hum. So while I am at it should I replace the pots and cap? The factory pots are all 500k and not sure of the cap (dark green) Yet the pots seem nice smooth turning ECT. Did they put nicer pots then the typical import crap in the VM? I am afraid of killing the tone. was looking at the vintage or standard pot kits from here: http://www.guitarpartsresource.com/bass_electricalwiringkits.htm Or I have a whole plate with pots and all wireing from a new jazz I bought off the bay to use, if I remember it has the 250k CTS pots correct? what is the cap on the factory pots? What would I lose gain with the going w/ 250 vs 500k? What about just changing the cap?
