"Ernie, do you ever go for a brighter and/or overdriven sound? How do the TC RS210's work for that?"
I only used the STM900 with two RS210 cabs at one gig so far. Had them stacked vert, of course, and female singer got pissed cause she said the mids were killing her ears, lol.
Now, this was with a blues/funk band in a small-ish, boomy club. So I used my modded MTD KZ5, Aggie OBP-3 pre w/Bartolini jazz pups, DR BB's. And this bass has very strong mids indeed. But I was trying to cut thru this boomy room, so I mighta overdone it some.

I backed it off abit.

But the 900 thru the RS cabs were letting the bass drive those loud mids and was pretty grindy and bright, so its' in there.
I was not going for a grindy tone, I rarely do in these blues/r&b/soul bands I gig with. But I feel my active basses get too grindy too easily with the STM-900 head, esp when I dig in abit. So I've been sticking to the P5 w/flats+TB153 when I use the STM-900, lovely tone that. Sometimes I'll take the Neox 212T cab instead, its such an easy schlep for longer hauls.
I'm using the two RS210 cabs w/900 head this coming weekend with a 55-02D bass in a new country gig. But I'll have the Markbass F1 right there too if the 900 gets too dirty for me. That F1 loves the RS cabs+ active bass, so I'll prolly switch over just for fun.
See I'm sorta still experimenting with these different cab/amps/basses combinations, esp with the 900 head. Its one thing when I try all these home-alone; another when I try them in a band mix at a live gig. Fun though.
