Are there any online tutors that you would recommend? Ive seen a few on YouTube but wondered if there are any you would recommend

i learned alot from Adam Gussow, on youtube, who has posted lots and lots of videos. He's also jamming sometimes which is great for getting inspiration.
i can truely recommend him.

Jason Ricci's videos have also taught me alot.

JP Allen on youtube (and www.freeharmonicalessons.com) also taught me a bit, but i find his lessons a bit too slow. The speed combined with the he talks made me feel like i was back in kindergarden. but if you're into that, then there's a lot to learn from him aswell.

i don't know if these are the one's you've been looking up, but here's my review nonetheless.

There's a lot to be learned from The Diatonica Harmonica Reference, but this guy comes across like an advanced physics proffessor or sumthin'.

true Gene, that one is also really great.
