I'm playing an Essex Jazz and I've been looking to change the pots. However, I know next to nothing about pots and after browsing through allparts.com, my mind is filled with more questions. Should I go for 250k or 500k? What's the difference between split, knurled and solid pot? What are the differences between linear, blend/balance and tone/volume pots? As you can see, I know nothing about them pots. I'd gladly appreciate it if anyone could answer my questions here in this forum, but I'd be equally thankful if someone points me to another website or thread where I can read up on pots myself. Thanks!
