So this is how cool it was: the band takes a break and I set up my Digitech RP200 into the PA. I take out an A Natural minor harp and start to blow a chorded riff with a Reggae feel, using one of my RP200 patches (a clean amp model with a low octave double–it’s my big accordian sound, really, only heavier than an accordian). The bass player joins in, then the drummer joins in, then the guitarist, and before I know it we’re writing a cool reggae piece on stage, with lots of blowing time for everyone.
So this was a super cool jam. The only problem I had was that eventually the one guitarist became two, and then the harp was a bit swallowed up by all those giant guitar frequencies. But hey–the band dug it, and it was great rocking out for a couple of hours with some superior groove merchants. I will be going back. Look for me there in a Sunday or two.
