Hello folks, I'm an owner of a Alfred Meyer 3/4 doublebass. Haven't found much info about this bass and wonder if anyone out there knows anything!? How much can it be worth? How can I check how old it is? And so on... It has some few cracks on the front and the right side. Otherwise really nice. It has an OLD sticker inside: > Alfred Meyer > Spezialität: Contrabässe nud Cellos > Markneukirchen i. Sa > Bergstrasse 559. Any ideas?!
