Here are some recordings of my custom Stambaugh bass.  The bass has Aero Pickups and a Bartolini preamp.  It has 5 knobs: volume, blend, treble, mid, bass (all cut or boost with a center indent) and 3 switches: one switch taps the pickups to single coil mode, one is a 3-way parametric mid range control, and the third switch mutes the bass entirely.  Finally, the volume knob is a push / pull that defeats the preamp, making the bass passive, when it is pulled up.

I am using Thomastik-Infeld Jazz Round strings, .43 -.89, and running the bass straight into the board without any EQ or preamp.
