Ok so I used thin cardboard from a beer carton instead of paper. Two layers at the front half of the neck pocket and could tune the strings.
On the low E the first fret is pressed down and then the 17th fret. I couldn't fit a business card or credit card under the 9th fret.
I have back bow on the neck so I gave a quarter turn to the left on the truss rod. No difference. I'm not going to go further incase I create a disaster.
Now that the bridge height is lowered to where I would like it do I need to do a shim or am I being too picky?
I'm not sure, it's still a big learning curve for me.
