Hi all, Gallien-Krueger MB500 ... about 6 months old. Stayed in one place since I bought it. It's a powerful little guy under 4 lbs and 350 watts @ 8 ohms - 500 watts @ 4 ohms. $375 shipped anywhere in the CONUS. Would consider a trade for an Ampeg BA112 + cash or a lefty P bass ... I know ... It's like trying to find a needle in a haystack! Thanks!
