Going from guitar to bass
So I have been playing music for 6 years now. I have a degree in classical guitar performance from a university and have my grade 8 from the Royal Conservatory of Canada. I also play guitar in a big band and also a small jazz trio. I have however decided that I am finished with the guitar - I really want to play bass. I started to teach myself walking lines on the guitar to accompany myself and now that's all I want to play. I do however want to play electric bass, but I came to the double bass forum because I have basically zero interest in rock, metal, etc and there seems to be a lot of that in the other forum.
I've gathered from this site that the Simandl method is a good way to start and build technique, but what Im really looking for is a good walking bass instruction book. I live WAY up north in Canada and there isn't really any options for finding a teacher here.
Any suggestions? Comments?
