Title: Shoot the Moon - Mucho Output
Post by: eldanko on August 19, 2012, 08:08:51 PM
Howdy friends -

Just finished building up CJ's Shoot the Moon trem.  It sounds great, but it has a TON of output... I'm getting unity volume almost immediately on the gain pot, and then tons more...

No part subs in my build... used a NSL32-SR3 optocoupler.  Opamps are TL072CN and JRC4558D. 

So... where should I look for my problem?   ;D

Pretty sure it's supposed to be like this. (Mine is.) :)

Change it out for a 5K (audio if necessary) and it's much more manageable. I did this on my recent mini one.

The proto I built went from unity gain to pretty loud.

You could try lowering the value of R13.

Ok sweet, so I DIDN'T do anything wrong!  (Sorry... I tend to jump to that conclusion rather quickly given my track record)

I love the sound of this thing.  It's easily the quietest trem I've owned.  Really great design culturejam!

Yes, GC... bout blew a hole through the wall with my Super Reverb when I first engaged...
