one of the models of theirs is very fast, but they also make slower
ones. I think the fast silonex model (NSL-32SR3<a
href="http://www.silonex.com/audiohm/product.html#nsl32sr3"></a>) is
just as fast(1millisecond rise and 2.5 millisecond fall), but Hamamatsu
conveniently leaves out specs on their "data sheet". The silonex ones
are much easier to get, BTW.<br>

a Japanese brand of LDRs, Hamamatsu (sp?), that has a faster response
than most? But I imagine the decay time is still proportionally as
long with respect to the attack time. I remember some people had
mentioned the Japanese brand as being so fast that they were more like
VCAs when used in compressors, Mutron III clones, etc., and not
suitable when you want the "soft" switching/turn-on characteristics of
LDRs (e.g. the way that Mesa/Boogie uses literally dozens of Vactrols
in their amps--my Quad Preamp has 32!).

in fact you could say that ALL photoconductive

the longer the turn off time)

This is due to the fact that you can bombard the
