so im getting rid of my marshall vs200 bichorus head, and behringer 400 watt cab, and i was wondering how much do u think i should let it go for, its a nice head, never been used for gigging, and i was given it for free, so i wouldnt know at how much to tell it for, and the cab is from musiciansfriend and it costs about 200, the head has clean/crunch, distortion1/distortion2, reverb, chorus1/chorus2, and has one preamp tube. so what do u guys think 500?

How much does the head go used for on eBay? That should give you a pretty solid idea on the price.
