I live in North Devon and, up until my decision to stop playing live a couple of years ago, was gigging regularly throughout Devon with a couple of bands (particularly an 80s tribute band which were always busy....). As mentioned previously though it is a large county so be prepared to travel if you want to gig regularly. Used to play regularly in Exeter (places like The Prospect, General Buller & Corn Exchange) and Plymouth as well as in and around North Devon. The Palladium Club in Bideford (pre lockdown!) hold a weekly jam session on a Tuesday night which is a good way to make contacts, introduce yourself etc
Cheers
