This Sterling Audio ST55 is finished, tested and sounding amazing. The Stock “resonator disk” capsule was replaced with my standard k47 style capsule. The sterling circuit boards were replaced with my BFM-T-55 circuit which is designed specifically for this mic and supports the pad and filter switches. The mic also has an internal pattern switch to allow selecting cardioid or omni pickup patterns.
The mic body has been de-branded and refinished in a matte blue color. It comes with the sterling shockmount and leather pouch.
