I'm talking to a guy about trading my 2006 Gibson ES-335 (Dot, plain top, gloss) for a 2012 Hummingbird. Does anybody have any opinions on the comparative value of these two guitars? Both are like new with cases and certificates. The owner of the Hummingbird believes there is a $400 difference in his favor, which could be true, I'm just looking to confirm. I thought their MSRPs were around the same. Thanks for any help with this!
