UFO and Scorpions guitar champion Michael Schenker talked about changing strings, telling Guitarist Magazine:
“Actually, I don’t know [when was the last time I changed my own strings].
“I used not to change my strings, period.
“Only just lately, because I have had a string go in the middle of a lead break, I’ve kind of started to get fed up with it.
“I like playing on worn-in strings, but lately, especially if we haven’t played for a while, I tell my guitar tech, ‘You’d better change the strings,’ just to make sure I don’t break any.
“It’s hard to remember when it was; I definitely did it before we played Japan – and that was last August. [Laughs]”
