Ok. I must admit. I've got a bad case of just-played-someone-else's-bass-itis. My friend has an older German bass (he thinks it's a Pollman, but isn't quite sure). Anyhoo, his bass has a great growl on the low end and the low E string, especially, sustains for days, which really helps with the tone that that instrument can get. He uses the same strings that I use (Obligatos), so I know that isn't the answer, so what are some things that can be done to the instrument to get that kind of sound? Any information is greatly appreciated.
