I've used this cab on stage with a GS212, and also as a stand alone cab at practice, and it can really move some air. I think it works great as a stand alone cab, with the tweeter providing some top-end zing. It has factory installed casters, and is really quite easy to move. It's in great condition. The only reason I'm selling it is because I've ordered a 2x15 cab.
Bass Player Magazine gave this cab a glowing review. If you'd like a .pdf copy of the article, let me know and I'll email it to you. Here's a snippett from the article:
-- The Aguilar belies the popular belief that 15s are slow, boomy, uneven, and sloppy sounding, and it proves that a well-designed 1x15 can sound deep and articulate while possessing a coherent and focused voice. If you're looking for solid, well-defined fundamentals with smooth and balanced mids, the Aguilar GS115 should be on your audition list. --
400 watt custom Eminence 15" speaker

I saved the original box and packing, so I'm willing to ship it. I'm asking $350 shipped, or $300 for local pickup.
This sale is for the cabinet only, and does not include the Acoustic amp, the basses, or the action figures in the pic.
IIRC, that is one of Ross's posters for "Kingdom Come". I also have the other two.
