I've got this Gretsch G2504 which I don't really use much on account of the pickups being pretty bad.
I fancy having a go at swapping out all of the electrics for new.
If I got kit such as one of these https://www.axetec.co.uk/guitar_parts_uk_028.htm
would it be a straight swap or would there be any measurements that i'd need to check for fit?
Are humbuckers a universal size or would I need to measure for replacements to ensure that they'd fit correctly?
I'm comfortable with soldering as I do it as part of my job but never had a go at wiring a guitar circuit up so would like to do so.
Thanks for any advice.
