I bought a very beat up mid 19th century German shop bass. I had a bunch of restoration work done on it. I put Obligatos on it. I don't like them. They feel OK, but not great. They're a little thin. They produce a lot of fundamental, but not much else. I am expecting more from this bass. By history, I play a lot of bluegrass and blues. I still have my laminated bass set up with Spiros and Golden Spirals for slap style. This old Humpty Dumpty bass is for other music. I want to bow it and pick it. I want to experiment with a brave new world of tone and sustain. I'm looking for recommendations for strings. Thanks.
