I'd have to have a few, using different technologies:
BBD: Yamaha E1010-uses 4 MN3005s for just 300 msec. Pristine!
Pedal format BBD: DMMTT for the flexibility
Digital: TC 2290 (if you've never heard one, you should try before they all die, it is an ear opening sound in stereo).
Pedal Digital: I'll defer this one
