Condenser Microphone Mod Service

Would you like your condenser mic to sound better?
To sound as good as a vintage studio microphone?

You may have noticed many problems when using modern condenser microphones: edginess, high-end peaks, uneven response, muddiness, noise. Even in quality branded microphones, there can be excessive noise and similar issues. The common problem, however, is thin, grainy, overly bright sound.

If you've done any overdubs, you may have noticed the tracks don't blend easily. The jagged, inconsistent frequency response of inexpensive microphones, makes it impossible to mix multiple tracks together without compounding these same problems. Applying EQ can't solve the problems—the entire response of the mic is at fault.

All of this is corrected with my component improvements and modifications. Your microphone will be smoother on everything, handle transients better, and easily blend with other tracks, and that's before you even touch the EQ. You'll no longer be multiplying problems when you overdub, so mixing will be easier and the sound will be better—allowing you to focus on the project instead of fighting with the microphone.

When you send your microphone to me for modification, I will remove the sonically inferior electronic components that adversely effect the sound quality, replacing them with the highest quality and most appropriate components, which will clean up the signal and correct the frequency response problems. I do not alter the appearance of your mic, remove layers of grille, or make any other cosmetic change that doesn't effect the sound. I only care about making your mic capable of capturing sound as well as it can.

Please contact me with any questions, and also visit my FAQ page.

I also service preamps, signal processors, and other recording gear. This can mean a substantial upgrade to your entire signal chain, for less than the cost of a single piece of high-end studio equipment.

Popular Mic Mods

Rode NT1000 Modified by John Bonnell.

Rode NT1000 mod—Perhaps the best all-around modded mic you can own. Extremely versatile with a neutral-warm sound. Put it in front of anything, and press record. Sounds equally great on male and female vocals, as well as violin, flute, sax, acoustic guitar, electric guitar amps, and drum overheads.

Rode K2 mod—Superb vocal mic. If you want that warm, deep, rich feeling of classic vocals, this will get the job done. Excellent on instruments, as well. Many have favorably compared my modified Rode K2 to the AKG C12. Top line vocal microphone for everything from country, rap, pop, rock, and classical, as well as an excellent instrument microphone.

Rode NT2-A mod—The FET version of the Rode K2. Top line vocal microphone for everything from country, rap, pop, rock, to classical, as well as an excellent instrument microphone.

Rode NT2000 mod—Identical to the NT2-A, with variable pots instead of switches for pattern selection, pad, and roll-off. The FET version of the Rode K2. Top line vocal microphone for everything from country, rap, pop, rock, and classical, as well as an excellent instrument microphone.

Rode NT1-A mod—Great all-around mic, similar in tonality to the Neumann U87 copies. Made in Australia, it's the cheaper version of the NT1000, with the same electronics, but a more mid-focused capsule.

Rode NTK mod—A cross between the NT1000 capsule and the K2 circuit. It tends to sound much like a combination of the Neumann U47 and U67. Excellent on vocals and instruments.

MXL 990 mod—A ubiquitous small diaphragm microphone for many years now, often misconstrued as a large diaphragm mic, it is actually a great copy of the Schoeps CMC "Colette" design. A very useful mic to have. Other makes and models of this SDC, include the MXL 603, MXL 604, MXL 991, MXL 910, MXL 770, Apex 185, Takstar CM-60, Sterling Audio ST31, Sterling Audio S30. Excellent for acoustic instrument miking and overheads, from drums to choirs to orchestras, and it can also work well on vocals.

Other makes and models of this type of LDC, include the Rode NT1, Rode NT2, MXL V63M, MXL V57M, MXL V6, MXL 992, MXL 909, MXL 880, MXL 2006, CAD GXL2200, Gauge ECM-87, Aurycle A570T, Avantone CK-40 (Stereo), Sterling Audio S50.

AKG Perception 200/220 mod—Another Neumann copy, same as the Golden Age FC1, etc. Reasonably priced, and well made. Excellent for vocals ranging from rock, pop, and rap, to country and voice overs, also excellent on acoustic instruments and guitar amps.

"…He wasn't just blowin' smoke—it sounds really good! The harshness and brittleness are gone, but the detail remains. Let me say it again—the NTK really sounds good!…"

Condenser Mic Repair Service

Is your condenser microphone silent, distorted, or otherwise non-functional?

Inquire with details of problem for an estimate.

Most problems such as static, noise, popping, or intermittent silence (cutting out), are typically caused by the same components I replace in a standard mod procedure. Sometimes more work is required. Very rarely does a capsule need replaced.

I can also usually repair and improve mics that have been modified by others, though this will entail an additional fee.

Turnaround time will necessarily be longer for atypical repairs.

Mic Mods For:

See FAQ for a full list of mic mods by model.


Tube Mics

Tube microphones require work to the power supply, as well as the microphone itself. Please ship all cables required for the mic to function.

Tube replacement is left to the discretion of the customer, and not included in the pricing of the service. Replacing the tube is not an actual upgrade or modification, but is an inevitable maintenance procedure with tube gear. In general, stock Chinese and Russian 12AX7, 12AY7, 12AT7, and 6922 tubes should be replaced, sub-mini tubes (often soldered to the board) should be left alone. All tubes, stock, replacement, NOS, or current issue, should be judged individually.


Prices:

Stereo microphones are considered two separate mics.
