Any advice on a microphone for an alto sax?

There seem to be two distinct requirements:

A single microphone near the bell for playing through an amp.
A stereo pair for recording.

I was thinking of using some of those Panasonic electret capsules:

and as the SPL at the business end is around 125dB I would need to
do the "source follower modification" to reduce distortion.

So, any advice from the professional recording engineers?
