Ive had several different configurations over the yrs. I've used EV cabinets with different heads. I had a TUSC head that had a very impressive Reverb to it. Ive used Ampeg and Peavey. I retired from playing out for a long period and had a nice Behringer BXL 1800 that I used at home. I got a call from a buddy who needed a bass player to cover some gigs so I lugged my rig and jammed out. Ran the amp through the monitors and it actually sounded pretty good. The guitarist was surprised how much I was peaking and vibrating everything...LOL
No clubs are all the same. Some have PA support, some don't. Some are bigger, and some are holes in the wall. IMO, a bass rig needs to be adaptable, somewhat lightweight and be capable of keeping up with a sorta loud band that isn't using PA support for the bass. The best rigs I've heard for this, all thing considered, are a good 4x10 cab and a 500 watt head. I'm found of GK for their customer service, sound and durability. You can get a Gallien-Krueger 410 MBE II 400W 4x10 Bass Speaker and a Gallien-Krueger MB500 500W Ultra Light Bass Amp Head for $900.00 to your door new. And even less if you use one of the discount coupons MF and GC send out once it awhile. You could always add an additional 4x10 MBE 11 when needing more, but really, for a club, that compact little rig with hang with the loudest of bands. And while Genz-Benz and Mark Bass, and Eden make good gear, it also cost way more and weighs more.
If you wanted to go with a 2x12 cab, GK also makes that for nearly half of with Genz-Benz charges. At 50 lbs, it's pretty lightweight and uses neo speakers and a horn. I had one paired with a Ampeg PF-500. Sounded very good, but I prefer the sound of a 4x10.
