Re: SG guitars
Yea, you can get a Gibson, but you can get a set-neck Epi and put in a pair of American-made PU's, and have one that sounds almost the same. I usually buy used guitars, and used PU's, and do my own wiring, so I can get a great-sounding Epi SG for $250 or $300. I can get 3 for what one Gibson costs, and use a different PU set in each (SD, DiMarzio, Gibson, etc). How's that for variety?
Problem with Gibsons is that their PU's aren't all that popular with a lot of players, so if you get a used SG for $750, many guys will want to replace the PU's for Duncan's, and your cost is still getting close to $1,000. My Epi SG's are about a third of that, and you'd be hard-pressed to tell the difference in a blindfold test.
Gibson uses A2 magnets on their Burstbucker, '57 Classic, & 490 PU's, and to me A2's just don't work on the neck PU of a mahogany body (dark wood, dark magnets, & HB's are dark by nature, compared to SC's). Too dull & lifeless. Their 490R/498T set has been trashed by countless members of this forum, but it can be improved a lot by swapping the magnets between them. Even then, a lot of people just don't like the 498T.
Gbsons usually still end up being expensive because of the (frequently) replaced PU's. In my view: with a high-end guitar you shouldn't even think have to think about replacing the PU's. Unfortunately, many are pulled out & sold onilne. I like going to a blues jam & having my $300 Epi (with SD's) sound better than the guys with their 490/498 Gibsons.
