As a bass player I always wanted a fatter sound so I used a preamp, especially with solid state amps. I was using a pedal that emulated an Alembic F2B and now use an EBS Valve Drive which actually uses a tube. Personally I think they add an extra dimension of fatness and can't play without them.
Do you use a preamp and which do you love?
