I've been with JJs since I turned 12 (I'm now 25 I think that might make me the longest serving student maybe). Can't recommend them enough, great teachers, great classes, great atmosphere, all the staff are very knowledgeable and know how to convey that knowledge over to the students. They've got all their own instruments so you don't need to take your own in (you can if you want to). Would recommend 100% to anyone wanting to learn an instrument or sing.
