I just got back from GC, and I picked up a used workingman stack consisting of a 4004 head, a 2x10, and 1x15 cabs. I paid $775ish, and they threw in speaker cables. It sounds great, the only downside is that the carpet is a bit scruffy (sorry for the crappy cell phone camera pic). I have two weeks to wait before I can pick it up, and 30 days after that to return it. My main question is, what year were these made? I see on the SWR site that they had an original logo which I can't find a picture of, then they switched to the red/black logo right before the Fender buyout. After that they used the "dome logo" (which is what I think these have?). Here are a few pics of the exact same head someone else had up in the for sale section a while ago: http://www.talkbass.com/forum/showthread.php?t=374958&highlight=swr+workingman+4004 They all came in from the same customer, so I assume they should all be from the same period. I can't find any archived pages online stating retail prices, but the guys at GC said it would've gone for at least twice what I paid when it was new. I have seen reviews online for the head where people have paid as low as $250 new, and some that have paid up to $800. I am fairly certain that I am getting a good deal on this, but I was hoping someone with more knowledge on the subject could enlighten me .
