Another run through GarageBand. The mini really struggles with it. Trying to lay down a second track just gives it fits. The monitor cuts out, which makes it even less musically enriching.
Worked through the Buzz Feiten tuning methods and reached the conclusion this beast has a really bad intonation problem. Old strings are not helping, to be sure, but I think the fix is more than $5 away.
Messy run through but I was making it up as I went and then forgetting it as I wrestled with recalcitrant equipment.
