the bass player in a band I had took the community college classical class. In that particular class, it was very orthodox classical nylon-string playing. He was doing the correct classical hand position and some really intense fingerpicking exercises. I was impressed with the pace of the class. It was really demanding.

If this class you are thinking of taking is the same (it probably will be totally different) you would be pretty frustrated with your electric. Also, if you are trying to play rock lead, this will teach you a lot that may not be so useful to you.

On the other hand, classical is really beautiful and that class would be fun.
