Ok, I did a TB search and did not come up with anything. Sorry if it's been covered before and I just missed it. Did all the older style (square, black, metal grate on front) 810 RR cabs come EV loaded? If not, is there a way to check the cab (model number, look of the speaker, etc.) and know if they're EV 10s or not? I have a call in to Mesa but I thought I would get feedback from you all. Thanks.
