I am currently considering purchasing a Mesa Powerhouse 1200 to replace my Carvin BRX 4.10. I normally use a 2050wattt Carvin full stack with the addition of a BRX single 18. The tone is AMAZING, but unfortunately it is far to powerful for small and medium sized venue. The Mesa looks like it should provide a very simular tone as my full stack but not be a sonic demolition tool like my current stack. I plan on keeping my 18 extention cab so i can run it at the large or outdoor venues. I use a Carvin B2000, 2ohm stable 2050watt head. I also exclusively play a customized 8 string octave bass. Because of that, i favor using cabs or stacks with different diameter speakers to fully showcase the tonal range of my instrument. If you have any experience with this particular cab, please let me know.
