The B1D is the same as the B1 except that it has an all iron BX4 output transformer giving it a more terrifying rock tone. An all discrete transistor, class-A, direct coupled, capacitor free circuit path, gives the B1amazing punch on drums, beautiful tonality on guitars, and warmth with presence on vocals.The B1D comes complete with both Gain and Level controls. If you want that heavy, gainy tone, crank up the stepped gain control and offset that with the level control. If clean tone is your thing, turn the gain down and crank up the level. For ribbon mics and other low impedance sources, the B1 has a transformer coupled impedance select. The B1 was rigorously tested with the popular Royer R-121 in the low impedance setting, and we think it sounds prettyf***ing bitchin’’ on guitar amps. The B1 gets the best out of any microphone, whether it be dynamic, condenser or ribbon.
