Hey... I know all about the lack of confidence... I play guitar to accompany myself when I sing... I know I'm not fantastic... I have some good friends who are guitar legends... current and future... I stopped singing a couple of years ago when one of my vocal coaches told me I couldn't carry a tune in a bucket... 2 weeks ago I performed Road house blues with a band that included a very famous musician... I had no voice, a cold and was shaking like a leaf... after the song he said "nice work". I have my new vocal coach Harmony to thank for that... the fact that I was there at all and the fact that I got through that song... she rebuilt my confidence... thats all you need... you can play the chords... so now feel the music and you wont look back...
Big Hugs...
