Anyone has a good sugestion (i.e. fatter sound, less feedback) for a setting when using a BM Ri and a Shure Green Bullet? I replaced the solid state rectifier with a tube and maybay I´ll change the preamp-tubes too. Nevertheless - when I think, I have found the right way I´ll be not so sure after a while. It´s neither the problem of holding harp and mic tight nor making a good acoustic sound.
