I am looking to get a new head, and the new cab I am thinking about getting, is the 8x10s. The heads- SVT-4 pro B4R Classic I tried out the SVT-4 Pro, and the Classic, and the SVT-350H the one that looks like a classic head. I tried out the 350h, and the peaking didnt go off, like how it does on my B2R, set up to the 8x10s, the same amount of power i have sent to 4x10s, and it wasnt peaking at all, like with my b2r. I dont understand? maybe my b2r is just a little used. The SVT-4 pro is nice, but a lot of stuff, when the Classic is basic and I like both. The classic head, sounded really good, and loud, but I DONT GET THE TUBE THING. The SVT 4 pro has so much power, but the classic is supposedly the best. How do tubes work? I dont get it. 300 watts, compared to "1600". Help, PLEASE!!!
