My friend GG – that’s how he signs his name – bought a new guitar. Playing it is causing some unexpected finger pain. The new guitar is not very different from his other one. He’s blaming the guitar’s neck shape and how his hand fits around it. But that difference is subtle at best. Maybe string gauge and scale length of the neck – both affect how tightly the strings need to be tightened to be in tune. But again, I don’t think so – differences may be noticeable but not that significant.
