Apex 480 Mods

The Apex 480 is a 3-pattern FET/transformer microphone with switchable pad and filter. It uses a familiar 2-stage emitter follower circuit and a common 32mm K67 capsule. The result is peaky and harsh-sounding on most sources. We recommend replacing the capsule, which is responsible for the mic's tone and frequency response.

Capsule Replacement Options

The stock capsule is a 32mm K67 type, found in just about every inexpensive large-diaphragm condenser microphone on the market. It has a peaky and uneven response that is not very musical, and tends to require EQ to fit into a mix.

We recommend replacing it with a K47 type, which will give a more neutral top-end response, with rich midrange detail. Our favorite capsule for this mic (assuming the stock circuit is retained) is the RK-47.

Another option is our RK-12. The voicing of this capsule is bright, but it sounds different than the stock GAP capsule; it has a smoother top-end response and warmer lows. It excels for female vocals.
