Up for sale is a vintage Gibson GA-20 RVT Minuteman guitar amp. The amp was made in Kalamazoo, Michigan, USA, serial number A025440. This one was just gone over by our amp tech and restored to good working order. This amp is in very good cosmetic condition, especially considering its age. It comes with its original footswitch. Please check out the pictures, or even better, come play it in person at Metro Gnome Music
