Gallien-Krueger 1001rb Mark II For sale is my GK 700 watt 1001RB II amp. I got it used a couple of months ago from a fellow TBer and it has been lightly used. It was scratch free when I placed it into my rack and it hasn't been removed since. There is a possibility of chafing from the rack. Everything is in perfect working order. Looks to be in truly great condition all knobs function smoothly. Asking price is $475.00. Shipped..
