Old IBM Thinkpad (will upgrade soon) playing BIAB "cold" right through a Yamaha 300W Pa with 12" speakers and a little Roland Cube I use for my monitor. I play my guitar through a little (but still heavy) Vox Tube Amp with a single 12" Speaker. I also use a Digitec Vocalist IV. I have everything but the speakers and guitar amp built into a rolling two tier stand that I set the laptop on. The PA speakers, stands and guitar amp fit nicely on a rolling wagon and re pretty easy to load, unload and pull. I built the PA,monitor/laptop stand my self, it too is on wheels . . . if you are interested in the setup I can send you a photo, just let me know.

Later,
