Wow am I impressed with the info on this site.
I just purchased my first Ovation guitar. It is a satin finish (spruce top? not sure?) model S778 s/n 555527 made in USA.

It was from a pawn shop so it has a few problems and I may have paid to much. I had never played an Ovation before and when I picked it up and played it a little I had to have it. What a sweet sound!

It has the OP24+ electronics and is missing a couple of knobs. Also has a small piece of wood missing from the sound hole decoration.... I didn't notice that until i got it home. The action on this guitar is a little higher than I like. I cleaned the guitar up a bit and I put a new set of 0.12 gauge Elixir polyweb strings on it and while doing that I gently lifted up the saddle and found the pickup is part of the saddle. The neck is in good shape just checking via strings depressed at fret 1 and 14.

So my first questions are....
Is there a process to lower the saddle height? On other guitars I was able to just sand down the saddle or remove shims. So this is a new adventure for me.
Is there and Ovation parts place where I could buy the 2 missing equalizer knobs for the OP 24+?
