For sale is my GK MB2-500. Purchased new by me and recently updated by GK to A07 revision level to eliminate an RFI problem I was having. Functions 100%. Shows one or two light signs of use, but easily 9.5 condition. I've made the switch to Genz, so I'm letting this go. Includes everything: footswitch with cable, power cord, all papers. $425 shipped to CONUS, PayPal ok. I'm looking to offset some of the cost of the new amp, so no trade offers please.
