I am pleased with GL-2NT, overall. For the price, I cannot complain. The instrument is well-built and looks nice in its plainness.
I intend to keep it in 'A' tuning. I understand many reviewers have purchased the GL-2NT as a travel guitar, but I cannot imagine it sounds nice in standard E tuning. The thing isn't built for it. Regardless, it is well worth the money, and is fun to play.
I had some minors qualms, however. The initial strings included were of poor quality, particularly the trebles (no sustain). Also, the action was too high, resulting in problems with the instruments intonation. I removed about 1.5mm-2mm from the saddle and voila; problem solved. 5 minutes of work to turn an OK purchase into a good one. I plan to replace the saddle and nut with higher-quality pieces and swap the strings. This isn't necessary. This guitalele is mostly fine out-of-the-box, but - as is the case with many budget instruments - it is easy to get even more out of your money. Thanks, Thomann!
