1. Call local teachers of other instruments. Ask them to connect you with students who match your level of accomplishment and enthusiasm.
2. Ask at your local music store. If they know you and trust you they will offer some suggestions.
3. Go to a local jam session and sit quietly in the corner for the first week or so to get the lay of the land. Then get up there and participate week after week. Make friends. Talk it up. It won't take long.
4. Online is cool, I guess. But, without some human intervention, you might just meet crazies.
If I can help, call me.
