Say a cab (like mine) is rated for 850 watts @ 4 ohms. What's a safe bet to max out through that cabinet, especially if it's one of quality design (like my Schroeder! ). Since I only need this one cabinet right now, I'm thinking of just getting a smaller poweramp and bridging it to get more volume into my single 1210. If that'd be feasible, I'd love to get a Stewart 1.2 or something. How much can you push it before you need to cut back a little bit?
