help needed!

ok guys(and gals), i have a question that i need answered because im not much on amp knowledge. ok, so heres the deal. i put a post of my Michael Kelly Fretless 5-string on craigslist, saying i wanted 400 for it or i might do a trade. this MK goes for about 600 new btw. so i got a responce from a guy from a local church with an offer for a trade of "studio stuff". when i asked him what he meant by studio stuff, he told me he had a SWR 4004 Workingman Bass head that he would trade with me for my MK.

i did what research i could and it looks to be a pretty sturdy amp. from what i found, im pretty sure it can outpower my GK Backline 600 that i use now. he said that its in great condition and sounds great.

so my question is this a good amp for this trade? im going back to all electric, once i get rid of the MK. has/does anyone use one? tone? options? just want to know about them.

thanks, Ryan

 

thanks. i did some more reasearch and it isnt what im looking for. my GK is working fine for me, so the MK is going to the bay.
