I just scored a pollmann gamba 1969, yaaaa, got it for a song . I love this bass, I practice, rehearse and gig with it (fully insured). I'm very pleased with the sound and easy of it, its very strong in low and mid ranges. The thing is when I got it, it was strung with Obligato. I like Obli's and have used them in the past, but they get thuddy fast. I find that they start to lose all the richness and overtones after about 4 months of heavy playing. I need new strings and I'm thinking about gut. My other bass I usually had strung with Spyrocores orchestrals so I have no experience with gut other than playing someone elses bass for a short time. Does anyone have any thoughts of what would be a set to string up?
