I am the director of a jazz program for teenagers. We have mostly electric bassists, and our bass teacher wants us to rent or purchase a db so that the kids can use it while they are in class here, and maybe get more kids interested in playing acoustic. Someone told me that graphite basses are now being made - they are inexpensive and obviously lightweight. They might be just the thing we are looking for. However he didn't remember the company that made them, and I don't know where to start to look for them (I am not a bass player) Any advise is very much appreciated. TIA.
