sorry for the late reply, i was away in europe and took a nice break away from computers.
i usually have the A and E strings at about 9mm (or 0.35 inches?)
i feel pretty comfortable with that height, give or take 1 mm higher or lower.
buzzing with roto can sometimes come the string itself, i had some badly made (new) ones. When i put new strings on, i run a finger along the strings to see if there are any bumps on them, especially on the A and E..
Hello thomas! I am a big fan of your work with Kings of Nuthin’ and love that fast slappin sound !
I want to ask if your action is 9 mm all the way or you prefer to have the D and G a bit lower?
