nah, might clip the FET or saturate the transformer depending on where you place it. I suppose there's an outside chance the diaphragm could hit the backplate temporarilly - no permanent damage.
I've been experimenting with a gain mod that actually changes the gain of the FET rather than putting an evil ceramic capacitor across the capsule as a 10dB pad as the stock mic does. This trick requires a bias tweak with a spectrum analyser so its not really plug and play mod.
