From what I can tell:
1) Buyer is 100% in the right. Color is nowhere near what he asked and paid the upcharge for. It doesn't matter the circumstances behind the first fucked-up guitar (of which there were several issues unrelated to this second build).
2) Kiesel should at least offer to refinish at no additional charge, or offer a refund of the upcharge.
3) A company their size should not have the/one of the owners also acting as customer service rep when it appears his skills in that area are lacking. While I am in no way a knowledgeable Carvin/Kiesel fan, it appears that from others the company has taken a serious PR hit in the last year or so from similar issues and responses. Jeff Kiesel needs to GTFO of the customer relations side of things before he buries his company.
If I am paying someone $2400 to build a custom guitar, and any particular detail I ask of them approaches anything near less than a 100% likelihood, let alone guarantee, then they better make sure I know damn well in advance that what I ask for probably won't happen, so can we adjust the order, or do something different, or call it off before we go any further, etc...?
