Re: need quick response...trade advice
I wouldn't trade 3 guitars for it regardless of how much dust they collect.
Ebay is such a crap resource for determining value. Just because a seller has it listed at that price--doesn't mean it will sell for that.
When you see typical RG550s in decent condition listed for much higher prices than better condition 700series, then someone's head isn't screwed on right!
Or, the 770 sellers just need quick cash--that's why you can't determine value by eBay listings.
If it was my situation, I'd just sell the guitars I really don't use, and save up for the guitar I want.
