I have an SWR Workingmans 300 that operates perfectly. The only thing wrong with it is that the "SWR" logo on the front of it has been nearly rubbed off. It delivers 270 watts into 4 ohm loads and can hand loads down to 2.6 ohms where it delivers 350 watts. I have recently gigged with this amp and it got me through a tight spot last summer. I'm asking $220 with me handling the shipping to the lower 48. I would also consider trades particularly toward a good playing but elcheapo 6 string bass---looks would be secondary. This would be a very good back-up amp for someone; it sure did the job for me.
