Hey John,
Sounds like you and I are in the same ballpark regarding the upright. I really dig playing it, but right now it's more of a specialty thing. I don't actually have a doghouse bass, I use a Zeta Crossover, it's pretty cool and it gets the job done well-enough! I never used the Taurus pedals, but I've still got an old Moog Rogue sitting around, definitely a floor-shaker! I read elsewhere on the boards about the floor-shaking capability of the SF-2, now I want one! It never ends, does it?
