There's a guy local trying to sell a '59 Fender Tweed Deluxe. The amp is worn and beat, but it is 100% original except for a 3 prong cord. The amp sounds great. I have a vintage guide that places it at $3,500-$4,000 in excellent shape, but it's nowhere near excellent condition, plus the Vinatge guide is from 2008 before the market went soft. What would you guys say is a fair price for this amp? Thanks!
