Apex 460 Mods

Apex 460 tube microphone

The Apex 460 is one of the best mod platforms on the market. We have multiple mod options for this mic, both sonic and cosmetic.

#1: Capsule Replacement

RK-12 capsule

The 460's capsule is a common 32mm K67 type, found in nearly every inexpensive large-diaphragm condenser ever made. It is not a great-sounding capsule, due to its uncorrected high-frequency peak. And it's the wrong capsule for this circuit, in any case.

Our favorite (and best-selling) capsule for 460 mods is the RK-12, which is our version of the capsule in the famous C12 and ElaM 251. The RK-47 is another perfectly viable choice, if you're going for a U47 vibe.

#2: Grille / Headbasket Replacement

C12 Grille for Apex 460

Our C12-style grille for the Apex 460 provides an easy cosmetic and sonic upgrade. The chrome grille not only looks sharp, but is more acoustically transparent than the stock grille, giving the mic a more open sound.

#3: Fox 460 Circuit Mod Kit

Fox 460 Mod Kit

The Fox 460 circuit mod kit is a comprehensive upgrade for the Apex 460. It replaces both circuit boards, 100% of the components in the microphone, and the transformer. It contains a critical mod to the power supply, as well.

One thing to beware of when researching mods for the 460 is that much of the information available online is contradictory. You'll see advice to change the tube and/or the transformer and/or selected capacitors, for example. Some of those things might help your mic, but none of them will come anywhere close to the sonic upgrade of a comprehensive circuit mod such as the Fox 460 kit.

Why? Because only by optimizing the circuit for a specific tube and transformer can the mic's performance be maximized. If you upgrade components piecemeal, you might end up with lower output and higher distortion than in the stock mic. In fact, one popular mod we've seen recommends using a 12:1 transformer, which will drop the mic's output by 3dB while keeping the noise floor the same. That's not a mod you'll appreciate, especially considering the $129 price tag on that transformer!

#4: Case Upgrade

Apex 460 Suitcase / Flight Case

Have the latches broken on your Apex 460's cheap plastic suitcase? Or maybe you're just tired of the fact that you can't stand it up without it falling over?

We've commissioned a short production run of custom suitcases for the Apex 460 and similar mics. These are made of aluminum, with locking latches, and CNC-milled internal foam. The case is more durable than the stock design, and provides better protection for your tube microphone.
