Re: When is action too high?
Your action is too high when you can´t play in tune anymore. Other than that, it´s purely personal preference, unless it´s so low that it´s buzzing all over the place choking notes.
I personally have arrow straight to just barely relieved necks, and as as starting point I set the high e string 1.14mm (I use my picks as a gauge, very practical) off the crown of the 12th fret (fretted at the 1st of course). the low e is set a hair higher, about 1.2mm, and then I fine tune from there depending on tuning and string guage until I have no significant buzzing even with my sledgehammer of a picking hand.
Anything under 1 to 1.1mm is to low for me to find enjoyable because of the way strings slip under my fingertips when bending causing unwanted notes. If I want you to make noise I´ll fret you, now shut up and let me bend. That said, thats only 1/25th of an inch, which is definitely regarded as a shredder´s action for the most part, and I can´t play on their piddlyass kinder-strings anyway. But I´m only slightly higher off the board with my bridge cables.
(Actually I CAN play them, in tune, but merely prefer to avoid it when I´m not being paid to be gentle

)
