I've got a PJB Sixpak in very good condition for sale or trade. Trades considered include Shuttle, G-K and Markbass amps along with small cabs.
Here's a photo of the PJB (disregard the EQ settings that my little girl played with). Sale price on the PJB would be $1200 and if trades are considered, I would suggest each person pays to ship their stuff. My gear is heavy-ish (88 lbs) so that works in your favor.
Here's a link to the manual on the amp. Note that it handles loads from 16 ohms down to 2 ohms.
