I also have a problem telling people I'm good. It just seems like a weird thing to say. That said, I'm never short of compliments from people telling me I'm great after gigs, and whenever I look out into our audiences there are always more people doing air bass than any other instrument
Then again, it doesn't hurt that I probably play with some of the best guitarists and the best drummer in Knoxville for our age bracket. They definitely help me sound better lol.
