So I have finally spent some time clearing a few other projects and am about to get stuck into this build.
I spent some time marking out the centre of the body today to get a few lines to help place the bridge.
I had previously read here somewhere about setting saddle positions at around mid travel and locating bridge with saddles at double the distance from nut to 12th fret......
But I also recall something about adjusting the G string saddle to more like 3/4 out and using the G string starting point. I haven't been able to find that again though.
Based on the 34" scale, the bridge is quite close to the pickup as shown in the pic below.
