melody makers are quite unusual gibsons, not alot of people have them.
Ive never seen on in real life before and ive been in all the shops in my city (4) and some in near by places and you only get LP's the odd flying V and xplorer and sone time a Firebird... that was sweet... anyways as for how much it could go for i ebayed it and some are on buy it now for 499 to 699 so you could make quite a profit on that.. with the BK installed who knows how much more you can get for it...
ive noticed that as well, in my local shop the guys who are usually quite moany gave me alot of respect when i came in to have my BK installed. they said
shop guys " where'd you get that pickup from"
Me - "ahh off the net, took a while to decide what to get ya know?"
shop guys-"ah well it sounds awsome in it, and ive not seen an LP in blue before, sets the guitar off nicely"
