I suppose the process is bound to change as guitars and guitar accessories evolve. I remember back in the 1970's seeing one of the first electronic guitar tuners at Rob Armstrongs workshop in Coventry. It was a Sony - the size of two bricks, and Rob had paid £75 for it, and I was chartreuse with envy. WE were in a group with a bloke who would reach over and tune my guitar onstage snf half way through a song!

I dunno if I am unusual, but these days I have an electric screwdriver to remove and replace the strings, lemon oil, guitar polish, always a choice of string sets, pliars to remove the pegs, a small screw driver to adjust the machine heads, various rags, string cutters.....

Is the music any better than when we used to break at least onstring out of a set from over tightening, and kept a ffew strings waggling in the breeze to stick your fag on.....yeh probably!
