[sdiy] unsolicited testimonial

Kudos to Ken Stone.

I just assembled his "Metalshop" wave multiplier board.  It lasted about

five minutes before I hacked it up.  thats better than average.

It worked right off. The board is VERY well laid out with thoughtful
EXTRA
holes for power, grounds, even a little playpen for those who (like me)
can't
stand to leave anything stock for long...

If I were to do it again... I'd buy several and chain those wavefolder
stages for
even more effect.  As it is... I added a fifth stage with the one extra
opamp...and
also changed the way the problem of 'breakout' is handled. I used an
bipolar
LED clipping stage in the fourth of the five stages.  Why does this work
better?
I don't know ;^P  It has the effect of reducing the fundamental
feedthrough by
quite a bit (which I like... I think... well I do TODAY... maybe
tomorrow ???)

Nice project, Ken !
