What has been your experience in the use of the limiter on the HHB
Portadisc?  I recently recorded a thunderstorm and realized that I
would end up clipping the big boomers without the limiter.  I found
the portadisc limiter to be very effective where unknown sound
levels are expected and ocassionally occur.  I am aware of the
distortion that limiters introduce, however I also have seen the
distortion that clipping creates.  I feel that limiting should be
used with care not to introduce pumping the sound levels (similar to
agc) and instead used just to prevent clipping unexpected loud

I am used to studio limiters that contain a great deal of control in
the attack, release and ratio of the compressed sound levels,
however the portadisc seems to work effectively in capping things
like thunderstorms, firework displays, and the such.
