Studio Projects B3 Mods

Studio Projects B3

The B3, like its Cardioid sibling the B1, uses a linear circuit based on the Schoeps transformerless design. It was implemented by Brent Casey of PMI, and is a very sound design built with excellent components.

Nonetheless, the B3 has a K67-type capsule, which on this circuit can sound peaky and bright. If your B3 is giving you more high-frequency content than you need, or if it sounds sibilant or fatiguing, we can recommend an easy fix: change the capsule to our RK-47.

The new capsule will give the B3 a neutral top end, with a broad and musical upper-midrange boost that enhances male vocals, strings, and percussion.
