This isn't really helping with tech at all, but I don't necessarily care.... took my bx1200 for it's first full testing and paired it up with my ls1503... Just with 2 guitarist and a dummer in a jam-band type setting. All was great and I had thought the amp was running bridged but I had to turn the volume up and I kept on seeing the peak light fade on and off... I was wondering why this was the case although I was still able to be heard (which is clearly a first for me) in all the notes I was playing (blues type music this run around). Throughout the whole gig I was fiddling a good bit with just finding a good sound b/c the possibilities are purely endless. As the night was nearing it's end I found my magic button, the bridge mode in the back... I clicked it in, I saw the a red light of doom shine forth and I was in heaven for the remainder of the night. All that headroom... it was the first time I had been able to play at a volume between 2-4 for both the power amp level and master volume level and still be a tad overbearing.
I love this amp, need to tweak the sound to get some more high's for slapping, but I doubt that'll be a problem. I was told I sounded good, and I'm just a very super happy camper. It does take a bit to fiddle with sound if a certain one is being looked for, but it's worth it and super nice to have the option of really hearing what your bass and playing sounds like through the song. I'm a very happy BX1200 owner.
