Before I get to the nitty gritty, I know there are three replies possible. 1. Do nothing. 2. Seek an adjustment. 3. Unwind the deal. My question really boils down to this: What effect, if any, do the finish cracks have on a guitar like this sold as a new instrument? Back story: I have never bought a new boutique guitar in my life, and as a result I'm curious what those of you who are more experienced than I think. As some of you know, I've been swapping/buying/selling stuff for a while, all as a hobby, and this scenario is new to me. Never had an issue on a guitar deal. I recently traded for a boutique instrument. Seller is a little known dealer and builder is not well known. The guitar was sold as New. The guitar arrived and, for the most part, looks GREAT. It also plays really nicely. It sounds great. My initial impression was very positive. I was giving the guitar a visual once over and found possible issues. They're the same but in different places. The guitar has some finish cracks. I've been told by one of the better builders around that this isn't terribly unusual and won't effect sound but that it's likely that more cracks will develop. One of the prime motivators in my buying the guitar is its beauty and in particular its top. Cracks on the top would not be acceptable at all. More on the guitar here: http://www.mylespaul.com/forums/other-single-cuts/329800-new-guitar-day-continuing-story-2.html I shared my findings with the seller. Seller's reply is that many guitars have these (including in his experience $15K Gil Yaron guitars). This may or may not be true. Thanks very much in advance for your counsel.
