Re: Epiphone Dot PU Replacement
You can carefully guide the whole assembly up thru the f-hole once the pups have been pulled off. The 3-wya toggle has to come off, but the jack is on a long wire and would be an absolute nightmare to get back in, so keep that in place.
The tip from T4D is really useful (I did that too) really helps get the pots back in place again if you tie the end to a bit of string or strong thread threaded thru the respective holes.
Note: If you are going to the effort of doing this, if any of your pots are a bit loose or crackly, take the opportunity to switch them out and upgrade, its worh an extra few $$'s while the dot's under the knife.
