I've been working on my relic'd Squire jazz (I know, it's lame) and want to change the two volume pots and tone pot. I like the tone of the passive Duncan-Designed pups on it currently, but the pots could be upgraded. Are there any benefits to getting 500k pots vs 250 pots? Which brand of pots are best? Some have said CTS, but from doing a search CTS has some bad reviews. This is my first pot replacement, so needing some insight/guidance.
