forgot to say
the se-50s are obsolete
not sure what else you can get that does all
this stuff
this was a studio-quality half-rack
unit that cost about $600 when it was new
people still use them though
they are 12 years old now
you can still get them on ebay for $150 or so
[of course mine came from a yard sale, though
at the time i didn;t realize how good it was]
be sure the display works though, they fade
and be sure it has the real power supply,
they are hard to find
they also do midi
and some of the effects can have stereo outputs

and they have enough gain that a mic can
plug right in, no preamp needed

but no wah-wah or autowah.. no downloadable
effects or programs..

i doubt it hurts the reeds, after all, closing
a stop makes for less air flow.

the problem with partially closing a stop is that
some reeds detune more than others.

it won;t be uniform.

though it may be close enough for a few notes.

also the next time you try it, it will probably
come out all different..

I'm with DP on this one. I believe that it would not take long for some of the reeds to go our of tune. Maybe all but some. Harmonicas go out in this way.

harmonicas only go out because you are also
REALLY blowing or sucking to bend a note, putting
much more stress on things.

my 2c worth

I agree, but some button box players do the same thing and if you have some reed banks partially closed off When you put the old air compressor hold on the box. Well you know what happens.
