I have a question that perhaps you could help me with. I am now learning string bass (I played primarily fretless electric). I have been renting a bass from my teacher who is willing to sell it to me. The bass is a Roth. I think it is 100 years old. He wants $3500 for it which he bases on the advice he has received. I really like it. I have found moving to double bass from electric relatively painless. It is easy to play and sounds great. This is pure instinct on my part as I have played no other string basses for more than 30 seconds. I could shop for months and perhaps I should It is not exactly in great shape cosmetically but is structurally sound. It is probably fine for its age. I don't know enough to make a judgment. If someone were to say ("I have a 1962 Fender Jazz in great shape for $3500" it would be easy. Advice would be most appreciated.
