With feet in the past and a brain in the future, the Stager SR-1A is a mammoth ribbon mic with some of the biggest, truest bottom-end you could hope to hear from a ribbon, condenser or anything else! The SR-1A houses massive Alnico-V magnets around a long ribbon in a precision machined aluminum housing. The output transformer, also made by Stager Microphones, is a toroidal design that's responsible for the deep bass, open, lulling top-end and depth of field.
