Nady SCM800 Mods
We have three modification options for the Nady SCM-800: replace the capsule with one of our premium large-diaphragm models, and/or upgrade the audio circuit with either of our our field-proven kits.
#1: Capsule Replacement
The stock small-diaphragm in the SCM800 is without question the mic's weakest link. It is noisy, with a peaky and unmusical frequency response. Fortunately, the mic's circuit will happily drive any large-diaphragm true condenser replacement, including all the Microphone-Parts.com capsules.
Because the mic's circuit is linear with respect to frequency, a K47 style capsule like our RK-47 or RK7 are the best choices. Both will give you a neutral top end, great midrange detail, and a much more balanced sound.
#2: "Pushbutton Filter" circuit upgrade kit for Nady SCM-800
We make a circuit upgrade kit specifically for the SCM-800. It replaces 100% of the mic's audio circuit, from JFET to output capacitors, and everything in between. It also optimizes the DC oscillator circuit, to raise sensitivity and lower self-noise. The modded mic is audibly improved -- in fact, it will compete handily with mics costing 3–5 times more.

#3: MP-V57 PCB Replacement Kit
For a bit higher cost than the above circuit upgrade, you could choose to replace the Nady's circuit entirely, using our top-of-the-line transformerless kit, the MP-V57. This is a full circuit replacement. The soldering task is somewhat is easier than for the "pushbutton filter" option, simply because the MP-V57 kit includes new, virgin circuit boards and as such does not require desoldering components (which is where most novices get into trouble).
The MP-V57 PCB kit provides an internal switch that can be configured either as a Cardioid/Omni polar pattern switch (note: Omni mode requires a dual-diaphragm capsule), or a 10dB pad.
Note: the MP-V57 circuit boards do not fit perfectly into the SCM-800 body. The mic's chassis rails might have to be spread slightly, and the upper corners of both new circuit boards might need to be reshaped slightly (via Dremel tool or sandpaper) to clear the mic's housing.
