I am also looking for a bass head/cab setup... for a high school rock band club, i.e. several rock bands each year. We play in our own medium-sized venue (club-sized), school halls, and yearly outdoor basketball court gigs... and go to other schools and perform in rock band competitions. When I'm doing sound with our school gear, I always mic the amps through our portable 16 channel board. I'm looking for solid, reliable and powerful, yet portable heads. I'll take whatever cabs I buy with us if the competition/school/club/venue doesn't have their own. We're in Hong Kong. More opportunities than you'd think. Anyhow, I am currently buying all new gear. For my guitar players, I just purchased two Orange Dark Terrors and PPC212s, and was thinking of staying in the Orange line (consistent "look") and buying an OB1-500 and OBC212 for our bass, but I haven't been reading good things about isobaric amps (hear that they're heavy and still no different in volume than a 112), and have been thinking about the 115 instead. My school is very supportive of good, reliable equipment that is not TOO expensive (no Hughs & Kettner). For us, switching to cabs/heads allows more flexibility when units die. (OB1-500 & OBC212 pushing budget) But then I started to look at other micro/lunchbox bass amps and found the Markbasses, and in particular that Markbass Little Mark III and New York 151 Bass Stack. So... questions: 1. How does that Markbass stack compare to the OB1-500 and OBC212 stack? 2. Is that shift in cost worth it? For my situation? 3. Any thoughts on the OBC212 vs 115 bass cab? 4. Should I rather consider another stack like that Ampeg PF-500 Portaflex? 5. Any other micro/lunchbox bass amps that I should consider? I want to stay portable and simple - none of my kids fiddle around too much with settings... basically plug and play. Remember that my students like, of course, the cool looking stuff and are quite sold on the look of Orange. Maybe I should stick with that since my two guitarists will be all Orange, but I need to be confident and able to justify it all to my school (like I said, pushing our budget). And, if I stay Orange, decide between the 212 and 115. All help appreciated.
