@Kristopher Swenson I fooled around with the truss rod on my Zager. It adjusted easily, however, the booming resonance has only been achieved with heavier gauge strings, which requires the string height to be higher than I typically like to play, to avoid string buzz. I still wouldn't get rid of the guitar... it's a beauty. Yours is looking good too! BTW, "given a Zager guitar". How did that happen?
