Looking for a little info... I'm playing through a GK mb800 now. I'm not using near full power.
I've always wanted to try a Mesa head, and may have an opportunity to trade for a silver face, black lettering walkabout head.
Will this be enough power to play small to medium clubs through 2 GK 8ohm 2-10" cabs? How about w/o PA support?
I don't mild a bit of grit in my sound, but not wanting to feel like I'm under powered.
Thanks in advance for any info...

Having done small/medium clubs with a WA and various cab combinations for several years, I can say from personal experience that it
can work out just fine.
What you lose compared to a more powerful head, like your GK MB800, is clean headroom. The other thing that the WA does at the top, and past the top, of its useful volume range is that it compresses quite a bit. So, IMO/IME, when you push the Gain to its max clean point for your bass (and whatever other outboard gear you use), and you run the Master much past 1 o'clock, you will just not get any more volume out of the amp, and will get increasing amounts of sag/compression. Dialing up the Gain with the Master at that point, will just get you grit that gets increasingly compressed/saggy sounding.
This situation will be offset considerably if you use cabs with more drivers and try and keep the total ohm-age at 4. As has been stated many times, the WA will do 2.67 and 2ohms just fine, but again, what happens - IMO/IME - is that compressed/saggy thing happens quicker with the lower resistance values.
Now, having said all that, I do not have any total SPL numbers to offer to back up my claims scientifically, so you will have to work out whether the volume level will work for you/your gigs. My advice is - get more drivers going.
oh, and let me repeat for the record, I am still
totally in love with my WA, and get the best out of it (at least for me) from the 104db Berg CN212. Even so, it does not go out on gigs where I need more clean headroom. For this purpose, the WA has been replaced (!) by a 11oow@4ohms Ampeg SVT 6Pro - which really delivers the clean headroom that I want on all bigger gigs.
good luck and enjoy!
