1) If the maximum point of relief in a fingerboard is at the octave, what shape is the relief? Does it follow a gentle bow from the nut, to come back to zero at the end of the fingerboard, or does it start and finish from some other point. Or does it follow a flat plane from the nut to the maximum point of relief, and then a flat plane back up to the fingerboard end, with a curve under the octave to join the two planes together? 2) What do the luthiers consider to be the average string height for jazz pizz on the G? I have heard that 6mm is considered "normal". I realise that every bass and every player is different, but there must be a median where you can say "well 75% of my setups turn out to be 6mm", or whatever. For what it's worth, I shaped my own fingerboard and it seems to work well with Velvet Garbos and a 5mm height under the G, and I play with a medium touch. I'm really curious to know how close to "getting it right" I was.
