I would use Ingen (formerly Om), but I do that anyway ;)
A pulse oscillator with some more or less subtle pulse width modulation
might be a good basis.

Add (Bandpass filtered) white noise for a breathing sound.

Now I don't know how a damaged reed sounds, I can only think of overblown
flute or sax.
Fast pulse width modulation (via a sine oscillator > 20 Hz) can add a
metallic touch.
The hard clipper or one of the tube amp effects, perhaps bandpass filtered
might do something for the sound. For extra breakage, feed a tube amp back
to itself (after a signal product with something like 0.1)
A pitch envelope could be made to fade in on high velocity (fiddly business,
though).

Building such a patch can easily eat up most of the day, even if one
already knows their way around Ingen, though :)
