So, soon i'll be taking three of my guitars to local service man to install new pickups, tuners, some electronics and to do setup of guitars. The thing is, i don't know how to tell him where to set the gauge of string action.. i want something not to high, something not to low. so somewhere around middle, i guess.. What's your favorite string action gauge ? i play a lot of different styles of music, from blues to metal, i use to band a lot.. please, write some suggestions.. thanks !
