It's a whole new rig for me (though the BF is well used), maybe it was just the punch from amp/instrument that I was hearing when I drove it quite hard. It tended to get a bit flappy when I really pushed it, but come to think of it that could just be the sound of the rickenbacker... To my ears, it sounded like the cab wasn't 'keeping up' with the amp when I pushed it hard. Which I guess is to say that I prefered the sound and responsiveness of it on medium volumes, compared to at higher levels.
