I have a cure...play more with supportive guitar buddies! Seriously, I’ve played in working bands for YEARS and can still get butterflies playing privately in front of people. But playing with a bunch of forum buddies can make you forget that phobia. No bigger grin can be plastered on your face. Oh, and if it makes you feel any better, my cats scatter as soon as I flip the power switch on the amp. They know to take sonic cover.
