I have a tutor, the second one I have had and cannot recommend it highly enough. My first was great at getting me through the first few music grades but was a guitar man, not a bass player and I was only learning by rote.
The new guy is a pro bass player (also possibly a member on here) and he has really opened my eyes up to learning about music and understanding what and why things are done. For me that is perfect, I am also really learning at the same time, it makes each Saturday something to look forward to.
One other major difference between the two is that the first guy taught but this guy gives me the tools to go and learn by myself - a true tutor.
