I got a russian bassballs the other day, and I love it. I'm still on the original batt, but it has a 1/8" phone style AC in jack. I was wondering, when it says a "9v AC adapter" do they mean an adapter that converts AC to DC (like most?) or just 120VAC to 9VAC ?? Any ideas appreciated... P.S. I know how to go about making a converter from boss style tip - to 1/8" tip +... so I don't need help there.
