Hello forumers, inquiring for your sagely advice. My question is about making measurements on a neck, for example height of a string above a specific fret. But the question is more general as you will see. Question is, if I have to sit a bass on its back with a rest so that the headstock does not touch the surface, where do I put the neck rest so that the difference in relief from playing position is minimum? If I place it under the first fret there is more relief. If I use a higher fret there is less relief, perhaps even less than playing position. The effect is real and pretty significant. Of course I realize this will change according to bass but I suspect around 5th fret would be pretty much ok. Any input with this? Thanks!
