thanks for the backup, TJ! i tried a 0.1uf axial ceramic "104" cap soldered
from MOTM-100's OUT ground to tip and am still getting the pitter patter of
little feet.... should i try another cap or am i not wired right?

Just took a scooter ride to the local Radio Shack (man is it cold here is
southeast PA),and picked up part# 272-996. It's a 1uF 50V non-polar
cap for $0.99. Seems to do the trick. I tried all kinds of caps and followers
and such, (ceramics didn't work for me) but had the best results with the
1uF elec. type.(connected between tip to ground).
I did notice a little difference in the resulting sound in the track mode. There
is
a different effect with the cap in place. So I'm still leaning toward a
"soft/hard"
switch to enable/disable the cap.
As far as anyone else getting or not getting a popping sound, your mileage may
vary.
Remember most of us are building kits, and many variables apply here. My unit
didn't go through Paul's QC after assembly. All units were not assembled equally.

Who knows what I may have done wrong or different.

PS: Oh yeah Paul, Ive been getting the popping in the "hold" mode. It's hard to
distinguish if there is any popping in the track mode?

That's odd! I get it more in the track mode than in the hold -- I can hear
the noise while the clock is high if that's my input to the S/H.

I hope your guitar player has a Fender Mustang and not a Gibson Firebird --
and I thought my system was crowded!

Yeah, that too.

I just want to say at this time those accusations are entirely baseless and
any previous allegations have never been proved in any court. Furthermore,
that any and all charges have been dropped -- she was merely a family friend
a little down on her luck. Boy, rumors travel fast!
