I haven't seen the DVD, but Dave uses:
Small flat back 3/4 French bass
Thomastik Spirocore strings (orchestral tuning).
AKG 406c condenser microphone mounted on the inside of the tailpiece so that the capsule is positioned between the feet about 1 inch from the front of the bass, and this goes directly to the house and monitor system.
Underwood pickup goes through a "Retrospec" tube D.I. that sends one line to the monitors and the house, and one line to my Gallien Krueger MB150E. This has its own 12" speaker and drives a Hartke 410 cabinet.
