thom -
here is a quick message. not quite an LED
but i put a VU Meter on my Psycho LFO. it's
very quite entertaining - if you'd like a lil schem
on feedin the VU meter - let me know and i can
upload it. i'd imagine a small vu meter (like old
battery power displays) would be great looking
on a stompbox! :) (maybe dangerous)
for the list - has any US builders out there
made the burst generator yet? i'm intrested in starting
it this week - but before i order the 12 position switch
i'd like to maybe hear from someone about a switch
that fits in good on this board? as i'd like to use that
as part of the mounting process
all the best
