I recently put my 2010 Rick' 4003 (in Midnight blue) up f/sale/trade on Craigslist. I'm selling it for $1000 which is probably a little low given that it's practically new and in good condition but I've also offered trades for any good old tube heads (i.e. old Bassmans, Sunn Model Ts. Ampeg SVT-CL etc). I've been offered a late '90s Fender Bassman 400 head and matching 115. Both are cream and I've been told the speaker is very nice (aJBL 151-4 -300 or so watts). I do know it's solid state but that aside know nothing of these amps. Does this seem like a fair deal? I actually do have a really nice old tube head; a Plush Royal 1060-s which is 100w but it's currently in the shop as it had been causing me trouble for a while (giving off a weird distortion) so I'm essentially amp-less until they let me know what the craic is with my Plush, hence wanted to do some sort of trade.
