I have a GK 1001RB gen 1 amp in excellent condition. This is the earlier 1001RB which is 540watts @ 4ohms. Its in perfect working order. It has been rack kept and well taken care of. It has some minor scratches on the outside casing but nothing out of the norm. Powerwise, its equivalent to the newer 700RB-II. This thing is loud and cranks. No issues whatsoever. Never had a problem. It always delivered. It comes with power cord and rack ears. I'm asking $375 shipped to CONUS only. No international sales. No trades please.
