Hi, the Gretsch virus has infected me... (Bad wording in these times) after buying and modding a G5120 from around 2008. I still am very pleased with the thin U neck profil, that soothes my aching lefthand thumb. After no reaction to my neck profile question (other thread) , i had a chance to check out some contemporary Electromatics and Streamliners in a music shop, all of them good (neck profiles). Conclusion: the budget Gretsches all have slim necks.... Now i pulled the ebay trigger on a 2008 G5245 Double cut Jet only to find, that it has a very chunky C-Shaped neck ... :-( Does anybody know, if its possible to sand the neck down, to a more pleasing profile ? Has it ever been done? Does someone know, if the truss rod in such a neck is a compession type running near the back of the neck or a modern type that sits right under the fretboard? Any information or comment is appreciated. Other than the neck profile the guitar is definitly a keeper: changed the neck pickup to a blacktop filtertron and omitted the tensionbar on the bigsy and it sounds great!
