no it's not for a truss rod - it's for wires (LED fret markers).

Agreed, it's an onerous task, but believe me, I'd sh*t myself more by way of heating the fretboard with steam, prizing it off with lever, routing some wire channels, sanding the glue off the fretboard and neck, and then putting it all back together and then aligning it back up - ie aka this guy's way...

....drilling a hole down the neck is the way to go!

I've knocked up a small 12 led (10 channel) led chaser & want to fit some LEDs in the fretmarkers of my cheap guitar as an experiment.
