The 'D' Neck issue..

[Arnold Schnitzer]

The current "standard" for a D neck is for the first finger to encounter D on the G string at the heel when said first finger is directly across from the thumb. I also was taught the Simandl "claw" where your second finger is across from the thumb, but current teaching seems to have standardized a more relaxed left hand technique where the thumb is either across from the first finger or hanging back some toward the nut. I have one client who uses the Streicher method and whenever he plays one of my necks he swears it's an Eb neck! His bass has a really flat D.

What it all boils down to is setting up the heel so the player is comfortable. Good players get used to anything, and many don't even know what "D neck" means. When necking a bass to be marketed, I believe it should be set up to the current "standard". Wood can always be removed, but you can't put it back.
