Strings action

[gianluca renzi]

Please,

can you tell me what do you think about double bass strings action? I usually use 6, 7,8,9mm but i feel unconfortable with the 4th string.

What do you suggest me?
Thanks

That's right on target, as far as I'm concerned. Where is it uncomfortable? Half position, around the heel?

What is the height at the nut? Should be ~35 thousandths of an inch up there.

Is there a lot of scoop in the board? That can make it harder to play in the A - B area on the E string.
