| Well , while waiting to be able to post in other Forum slots .... I will start to work.
My goal is to help the community to get info on the OVATION OP PRO.
This is a Classicl Preamp who deserve to be maintained ,repaired and enhanced.
But no way to get it repared or improved as no schema are available..
Then what ? Then me!
:-)
In the next months I will analyze deeply the beast trying my best
to reverse engineering it.
Th initial phase will be hard.... But... there is a lot of whort value....
Hope to make a service to Ovation Owners...
For the time being I quicly arrange a blogspot:
http://proreverse.blogspot.it/
A piece of web garbage... but I want me to concentrate on the electronic not on the HTML...
I will post here my progress gving an alert here.
To start.... 2 macro of the OP PRO 2 SHELLS OPENED
Best regards
:-)

| I found the 1st piece of the mosaic.
Basically all the section responsible for elaborate the piezo signal (once buffered) in a way that can be sent to the Tuner Circuit IS EXACTLY THE SAME AS THE ONE USER ON THE OP PRO24+ :-))

Location: The Great Pacific Northwest | I'm moving this into the Lutharie section as it's in the Welcome Center and you have full access.
Anyway... I was looking at "only 55% of available piezo output is used!" and I'm wondering if you did any A/B (before/after) recordings. A couple of things come to mind as the reason for 55% of the output. Feedback control and overall tone and based on different strings, what does happen crank the output on the pre-amp to 100%?
