AT2035 Microphone Mod Kit

The Audio-Technica AT2035 is a popular starter microphone, with robust build quality, reasonable frequency response, and useful pad/filter switches. This upgrade kit takes the mic to the next level by replacing the entire audio circuit. The mic's existing capsule is capable of good performance. It avoids the sonic sins committed by most inexpensive microphones. It provides a relatively flat frequency response, and controlled proximity effect. It works well for close mic placements. We retain the original capsule in this mod because the new circuit unlocks a level of performance not achieved by the original circuit. The new circuit is based on the Neumann KM84. It is a single-stage JFET design with a custom output transformer. The circuit is tuned to provide some second-harmonic coloration under moderate SPL. This design gives character to vocals and acoustic guitar tracks. The modified microphone has 3dB higher output, and slightly extended bass response. The simplified signal path, ha
