Anyone use a B4R in gigging situations? I had an SVT3Pro one time and have tried several 4 pro's and just don't like them. My reference points are V4B Magnavox era, and a B2R SS. Two completely different sounds. I like the sound of the B2R but in a gig situation it tends to come up a little weak. And yes I am running at 4 ohms. Have been looking at B4R's but not able to find one close to demo. Sort of like the Ampeg sound, but wanting to have a clean SS sound with some more pump available. Anyone?
