SWR SM-500 Professional Series amplifier head in excellent condition. This is the version with the desireable black and red front panel. Super clean, no issues. A handmade classic from before the Fender buy-out. Asking $600 shipped--a fair price as Musiciansfriend sells these for $1,199 plus shipping. Purchased recently, taken to one of the top East Coast amp service centers (Music Technology at www.musictechnology.com) for a full inspection (an $80 value). The amp checked out perfect. While it was there, though, the gig fell through. Includes original paperwork and the SWR speakon cable you need to run the SM-500 bridged I have over 130 transactions on the E with 100% positive feedback. Questions welcome. Thanks for looking.
