I had the BA330 for a while, but never warmed up to it. I practically gave it away to my horn man. Now, we’re using it to fatten the sound of our backing tracks. We place it behind us, patched into the sound system. It provides a nice bump and ambience to the over sound. Sort of like having a sub. No feedback issues. But, I hate to carry that thing.
It's only 30 lbs. kind of wish I kept mine for a utility and practice room amp. For the price I would still choose it over the new Bose or Korg.
