Someone offer me a Guild X150D (the guy told it's an XD-150?) in a trade of a Martin D28 that I did not play really often. I surf google to find the value of the Guild. For what I saw I can set the value around 1200$. Am I right?? I already have a Gretsch 6120W-1957 (Dynas and P90) and the Guild will fit the bill for humbucker style guitar. How the X150 compare to a Gretsch with Filtertron? Am I losing to much on trading the Martin D28? :?: :?: :?:
