I have over 30 years experience with acoustic guitars, and in those 30 years I have approximately 18 years as a acoustic guitar instructor. I have less than one year instructing electric guitar and bass guitar.
I also have experience instructing children with physical disabilities (missing fingers)
If you truly want to learn, by the end of the first lesson you will be playing a nice recognizable rhythm to a song.
A lot of instructors start you out tuning, notes, guitar maintenance, ECT. Not me!! We go right into having fun, and learn a little bit at a time of all the other things along the way.
