I was just pondering a possibility: bi-amping my Rumble 60 to the low end of my bass and my Spider II to the high end. Now, we all know plugging a bass right into a guitar amp is a big no-no, but what if it's solely responsible for the treble end?
To me it seems as if it would work, as long its only the high end/high mids etc going into the Spider.
How do you do that. It sounds like a good idea.
