Comments about Four Force EM-1 Guitar Amplifier:

I belong to a jam group including two professional teachers. I hooked my unit to a Marshall 4 x 12 at the studio. WOW. It played clean until I really got on it, then it got dirty as advertized. The teachers were impressed and kept playing with it. 5 people in the group and it easily kept up with everyone else's equipment. Light as a feather. So inexpensive I'm buying the two other guitarists one as a gift. Having it tilt toward your ears was a simple but excellent innovation. Warning to other manufactureres: Its catch up time!
