I'm going to need a bigger and louder cab for some outdoor summer stuff. I just tried a used one of these and really liked it. Very full and balanced sound, highly efficient (I use an old Hartke 200w head). two 10"s + adjustable tweeter. It's not huge but still seems like all I'll ever need for the bigger stages. I did a search and no one has mentioned this cab. Anyone out there use one for upright?
