I have a Cort electric guitar, I've had it for 3 years now, but suddenly it has started de-tuning during my live shows. I've tried various makes of strings, but I found that "Ashton's" gave me a great Strat sound.
There doesn't seem to be any warp in the neck, and the string hight hasn't lifted. Could it be a crap set of strings?
Any suggestions and good advice would be welcome.
