Burl B1D Microphone Pre-amp

The  Burl B1D is the same as the Burl  B1 except that it has an all iron BX4 output transformer giving it a more terrifying rock tone. The B1D provides up to 70dB of gain and features a -30dB pad for especially hot signals. Dig into the input gain and back off the output level for more input transformer saturation, or flip into the low-impedance mode when you’re using ribbon mics…or both.
