My bass has a fairly decent crack along both sides of the neck heel. Luthier estimates at least US$1700 - obviously unviable for my bass - to properly repair (remove back etc.). Otherwise he can affix the neck with a screw (c.US$ 100 - 400), which if done properly, I'm sure will be fine. BUT the work will be not be guaranteed. Luthier is reputable and I'm confident repairs will be ok, but I am dissapointed at a guarantee not being offered on the cheaper option...is this commonplace?
