So I never did expect to copy the Senn-Eastwood exactly. I'm not using the Jaguar-Style tremolo ( I have a Jag Body coming in from another source, I'll deploy it there. )
But a problem arises without the big tremolo whammy assembly on board. Now the guitar didn't look right with all the extra real estate on the ass-end. Almost half the guitar is doing nothing.
So I took an inch off the tail .. but first.. on my duplicate styrofoam cutout.
Sure enough, on test I realize that I lose too much at the 6:00 position following the cut. I lose the space where I rest my palm when I play. It was clear on the mock cutout, the new design was going to be cumbersome.
So I go back to the drawing board. I did trim an inch off the bottom, but with a modified cut.
This let me keep my palm rest area, guitar is 1" shorter, plus the bottom line intentionally follows the same angle as the guitar's shoulder.
It's oak by the way. This is it lined up. LOL oK no more about this one.
