for what its worth, i reckon the seller is being entirely honest, and that its a good guitar for the money.
i'm penduluming ;) secondhand jacksons rarely come up for sale. if i could get a black/gold RR5 or a Fernandes that would be ideal. i hear what has been said about the negative point of the bolt-on neck.
Soho Soundhouse have offered me a deal of £630 for a Kevin Bond Rhoads, and £699 for an RR24. Those are good prices, but obviously second hand will give me much better value. I've always been one for buying secondhand, and letting some other guy taking the depreciation hit.
