I am curious about the devaluation caused by a couple of repairs.
Removing a frog from a bow stick can be quite a delicate job, and those who do it incorrectly risk the eyelet catching the stick and chipping it. A repair I often see on bows is some sort of epoxy filler to cover up this common mistake. It is not the prettiest of fixes, so does it have any affect on bow value?
Another common damage I see is that some bows have warped ferrules due to a tight spreader wedge. How severe is this damage?
Also what would be the effect of a bushing to a valuation?
