totally understand buffbillh.
One of my best gigs I had was when I used my STM-900 with two, 8 ohm Epifani UL410 cabs and my 55-02D in a traditional country/modern country band at a very large outdoor biker bar. That rig sounded awesome but I only used two cabs that one time last summer. Aint luggin two large cabs around no more. First time I ever did two 410's. I had just bought the second UL cab and had to try it once. OK, got that outta my system. Wasn't a real big hassle just dont wanna make that a habit.
And buffbill if you recall I mentioned I recently did a outdoor gig with my blues rock band outside of a Houston Central Mkt. I used a single NeoX 212T (no PA) and the STM-900 with P5 w/flats. With the SVT settings it cut thru real nice and with master @ 2:00 the rig punched along nicely. I was asked to turn down. I like to use the NeoX cab when I know I have a gig where the setup can be a long walk or thru heavy auto/ped traffic. Its just my easiest cab to lug around. I use my little folding cart so it comes along nicely from large parking lot onto gig area.
Maybe a Uber 410 would do ya good? They make em in 4 ohm right? I almost bought a new one last spring but found a hardly used UL410 here on TB so I went with that to have two 410's. Now I just sold that second UL410 to a TBer last week. Never needed/used two 410's since that one time.
Think I'm gonna keep the other UL410 afterall as I still really like what my BBE or Alembic F-1X pres w/Crown XLS1500 will do bridged @ 8ohms for about 1100 watts.

Two bands I was with last couple years gave me good PA support so I was bringing a single 212T or even just a Eden D210T to gigs. Those gigs have slowed down and now just started wtih new band that offers no PA for bass.
This band is doing Motown/Stax/Classic Rock. I'll use the 212T w/STM-900 at small club gigs then the UL410/pre/pwer amp at larger clubs, etc. You gotta do what ya gotta do for the gigs man.
But now I'm kinda looking for a GB 9.0 or 9.2 to use in the new band for a cleaner tone. Maybe a pre pedal into the STM-900 effects will work too. Sigh.

It never ends I guess. peace y'all. e.
