First off, what is the biggest Neck-Stand (from the Top to the underside of the Fingerboard) you guys have ever had or seen?
My Basses that were recently restored with the Necks re-set average from about 34-37+mm (1 3/8"-1 7/8+). I have heard of some using 40mm as a standard measurement as well.
My Big Bass was supposed to originally have the Shoulders Cut to get it down from a 44" String length to a 42" and then we opted for just a Block-cut instead. Towards the end of the restoration Biase lowered the Neck slightly into the modified Block and pulled the new Grafted Neck out at the heel to over 50mm. he just measured it over the phone and the current dry-fit is about 55mm or 2 3/16" out from the Top.
The Bridge was also placed on the upper most position that shows wear from before which sits just above the FF notches as seen here from the old scars;
Within the next week or so I will go into NY to meet with Biase and finalize the neck-Stand and String length. We are well within the 42" or less number now but I will do some final measurements when I get there. The Pitch he has the Neck at now is planned for about 10 degrees. I don't know if that is steep or shallow but I will have a look at it in a few days. I have no idea what pitches my other Basses are and I doubt any two are the exactly same as they all feel different when comparing the most recent 3 restored Basses, the Gilkes, Hart and Martini.
Because of several factors about this Bass like the long body length, the long original string length, the extra wide upper bouts and the Rib area at the Block that tapers down to 5 3/4" (from 8 1/2"), Biase feels that this Bass is now very playable without any cutting whatsoever. The Body and Shoulders of this old beauty has been respectfully preserved now 100% to its original build or at least from what we can tell.
