I'm sure this has probably been discussed at some point, but I'd like to run it by the current Talk Bass community. What do you do when you only have a 4 string bass and the guitar player pulls out a 7 string? I ran into this at a band try out the other day. At first I was worried that I'd made a mistake by switching from 5 strings to 4 strings recently. I asked the guitarist if he was going to be going below D in the song. (thinking I could drop my E to D) He said that he would be using the open B string, so I stayed in standard tuning and played it with the B and D notes that I had. (2nd & 5th frets on the A string) I was kind of surprised - I thought it sounded just fine playing my bass line in that register with a 7 string guitar hitting his low B. Is that a pretty typical way to handle it, or do most guitar players with 7 strings have bass players with 5 or more strings?
