So this uke came in
with a bridge that was cutting into its nylon strings, a typical ukulele adjustment job, when I was surprised to find it had an adjustable truss rod. Apparently they only exist in ukuleles made by Pono. We used fresh strings from AntHillMusic.com.
If you’re garage hunting for a ukulele with perfect tone, here’s a tip: keep your eyes open for a Pono ukulele from Hawaiian manufacturer Ko’olau. The Pono series from Ko’olau are the only ukuleles that are made with adjustable truss rods. It means that you can adjust the curvature of the neck to dial in the exact string tension you desire, perfecting your ukulele’s tone.
You can spot a Pono ukulele by a headstock logo that looks like this:
Quick Tip: If your ukulele’s bridge is cutting into the nylon strings, you can smooth it out yourself with a very small chisel file. Be careful! If you file it down too much you’ll have to replace the bridge.
