The compliments I've received throughout the years were few and far between, within the context discussed here (meaning, from qualified ears...guitarists, other musicians or an enthusiast that cares and knows the difference). But, those sure served as affirmation and helped me conclude that I was doing something right. That's why I try to do the same when I go to shows...it's nice to get a compliment.
Sure it's nice to get a compliment! But...I record what I do with a guitar.
So it's right there for me to listen to and compare with other stuff I hear, and after 25 years or more in the studio, I know how to interpret what I'm hearing.
Third party validation is fun, but not necessary.
