I'm looking for a good bass teacher now. I see many teachers that are primarily guitar teachers that are also giving bass lessons. Is it worth trying or it's better to find a 100% bass teacher? Has anyone had any significant experience with bass vs. guitar/bass teachers? How important is the preferred music style of the teacher? For example, if I'm going to play mostly blues/rock and there is a good teacher that mostly plays jazz. Is it worth trying to find a teacher who is oriented on the kind of music I'm more interested in (but may be not as good teacher as the other one)?
