Re: How to fit EMG pots to CTS holes?
Make sure that the pots you have in your guitar are long shaft. I believe the EMG ZW set comes with the long shaft pots and if that's not what you have you'll either have to use a washer to bring the pot to the correct level, or get the new pots all together.
If you're getting new pots, and not afraid of soldering, just get 25K Bourns short shaft pots or 25K CTS long shaft pots (depending on what you have). Or you can get plastic bushings (like eBay item number 111046660641), but those are expensive for what they are.
