hi Ya'll. my second OD is a maxon od9 and imo its one of the best tube screamers going. I see that they now have the od9pro + and 2 or 3 other od9 versions. Just wondering if anybody here has tryed these others. the od9 pro + is supposed to run at 18 volts so i'm thinking it might sound cleaner/clearer than the regular od9 set at low gain. Thinking light breakup like some Hendrix stuff "wind crys mary" interested in your findings Thanks Guys!
