Sterling ST55 Rebuild


SKU: st55u Category: Tags: , ,

This is a rebuild of YOUR Sterling ST55 (Groove Tube GT55) Mic

The ST/GT55 is a solid well constructed mic. With this rebuild, harsh, sibilant high-end becomes smooth and silky. Thin bottom end becomes full. In the middle is a great harmonic richness that works well on almost anything you throw at it. The transformer brings some fantastic dynamics and saturation characteristics.

Standard Upgrade

  • k47 style Brass Ring Capsule in Custom Mounting Cradle
  • All-discrete BFM transformer coupled circuit with Internal Pattern Switch

Transformer Choices

  • The imported (China) T8 style.  This is low cost transformer which performs pretty well. It has a slightly thinner and brighter tone.
  • CineMag (USA) 5722w. This is a very high quality transformer which is still moderately priced. It has a very full, even tone with great harmonic content and transformer crunch. Probably the best choice overall for most applications
  • The Tab-Funkenwerk (USA) T12 style. This is a more expensive transformer. It has a massively fat and full low and low-mid response. Although it has great high frequency response, you may perceive the overall tone as slightly dark because of the extra full lows and low-mids.
