I don't have a Deluxe, but I do have a Sig Standard. My rig consists of an Alembic F1-X preamp, SF-2 Superfilter, a QSC 1804 Poweramp, Furman AR-1215 Voltage regulator, a Korg DTR-1000 tuner, and Ampeg BXT series cabinets (2X10, 4X10, and 1X15). I use it for all my basses, and the SC sounds great through it. I also have a Mesa Boogie Walkabout Scout 12 combo, and a Phil Jones Briefcase, both of which sound great with the SC (and many of my other basses as well).
Every Alembic I've played through an EBS sounded absolutely fantastic. It's one of the reasons I picked up the SC Standard (in Seoul, South Korea).
If you want something with gobs of power and tone for days in a small combo, though, my recommendation would be the Mesa Walkabout Scout. If you can't get that, EBS is a great amp as well.
