I ordered the Harptone baritone kit without the sound hole cut so that I could try doing a simple inlaid rosette. Could someone tell me what the usual sound hole diameter is on a baritone?
I'd start a little smaller than the chart recommendations so you can "tweak" the air chamber resonance. I had a guitar that had a bad resonance in just the wrong spot. Reducing the soundhole size might have fixed it, but it was a finished guitar so that option wasn't available to me.
I wouldn't loose sleep over it. There are a heap of other things to consider before you start tweaking the size of the sound hole for optimum performance.
Yeah, and this is a somewhat unproven design and my learner building skill is going to add a whole lot more variables than the size of the sound hole. BTW I think the kit as designed comes with a 2 3/8 sound hole.
