Thanks. The Mini came with and was set up to work with mediums. I just got it a couple weeks ago. I'm a beginner so I figured lights would be easier. But you all say, the tension is less due to the shorter scale, so I'm going back to the mediums to avoid problems. Even with an untrained ear, the tone is way off now with the lights. We're heading to Alaska in an RV and I'd rather avoid the guitar getting out while up there, because I've changed the strings.
I've got a Korg GA-30 and a TM-50. I need to learn how to check intonation myself so I can better diagnose issue and maintain my guitars.
