Having owned my instrument since 1992, I am now considering making a change for something with different qualities. The question I have for those with experience selling basses is how do you generally come up with an asking price? About 15 years ago it was appraised at $9800, but I doubt it would actually sell that high - it was for insurance. (BTW, it's much harder to get appraisals these days!) It's a 1930s German bass with the name "Hammig" inside - it seems no one has heard of this maker. It's in good playing condition, plenty of cosmetic blemishes and repaired cracks, but otherwise solid. Any words of wisdom?
