I picked it up today. So it turns out its the earlier version, the "Basic 350" ...I think that dates it to '93 or '94 IIRC. I tested it out for a while and was pretty impressed with the tones I was getting. The mids-level and the frequency knob for the mids is great. You can get this thing pretty full and bassy just by doing what you guys recommended, rolling back on the mids level and treble rather than pumping in more bass. With the gain and Master up pretty high through an 8ohm cab there, I was shaking the walls, so I think with a 4ohm cab and a little extra power, I should be covered volume wise. We'll see...
I didn't get as much trade in value for my other stuff as I'd hoped, but thats usually how it ends up at Music Go Round. But our craigslist here is 100% sellers with nobody buying, so its either MGR or ebay
