First series (not the newer class D version) that according to many sounds much better... and yes, I've tried both and this older line with the analog power section is better. Not very heavy, probably 8kg. 450w/4Ohm, pretty clean and works perfectly.
I'd gladly trade it for an Ampeg SVT2 (of course adding money) or with a Terror Bass. Will also sell outright for £350 shipped. Can't attach the pic, please drop me a line if you're interested. PayPal is OK.
