I've been taking lessons from a guy for about three years, we took a break over the summer and I haven't called him about starting up again. The guy I take lessons from is mainly a tuba/bass player, he is the head director of our high school band and also does jazz band, so he is more than qualified to give bass lessons. About a year ago I feel like I hit a wall when it came to learning theory and improvising, his method for teaching that was showing me the basic stuff then saying I had to figure it out on my own because that's how he learned it. I've gotten a little better at it since then but no where close to where I hoped to be. That method of teaching just isn't working for me and hasn't worked for over a year. I've told him before that I don't care if we don't play one note during our lesson, I just want to understand theory and improvising more, but the next time we meet its right back to learning a new song or something. So should I try and find someone else or keep going with the guy I have now?
