When I left one of my JMJ mustangs on a hercules headstock dangler type of stand it developed black stains in the area in contact with the stand. I was able to clean it up so there is just a faint dark mark now, — not really a problem on a roadworn instrument, but to prevent this reoccurring I ensure there is at least one layer of t-shirt between the bass & stand at the point of contact. Not ideal but 'it is what it is' as some would say.
Can anyone recommend a specific stand (masnufacturer & model) which is definitely safe out of the box for instruments with nitrocellulose lacquer?
