I’m looking for advice for new strings for the Larrivee 12 string I picked up the other day. It has light strings on it now and they need replacing. It’s a 35+ year old guitar. The action is great. I don’t want to damage the guitar with too heavy a gauge of strings. I think the strings on it now are 10’s. I’m mostly a strummer with a pick. I play about 50/50 plugged in/acoustic. I’d like a little more volume acoustically and just a touch more bottom end. Thanks in advance for any suggestions.
