As a beginner guitarist, I have no joy playing this guitar.It sounds crap and oddly nasal(?) compared to any other guitar I’ve came across.Also the “tune” buttons on the guitar are basically decorative since they do NOTHING.
I guess it’s “worth it’s price” and nevertheless it’s better than nothing.

Not recommended due to poor inconsistent build quality. I have just bought two Sx guitars both teles. They are low cost and are generally considered by others to be good value for money. However the build quality on both of mine leaves a lot to be desired.
One has hairline cracks in the neck pockets and the frets are cut too short so there is not enough fret room for bending and pulling on the top e in the upper register. The frets need a polish as they grate slightly when bending notes.
The action can't be adjusted properly on both guitars as the action is still high when the saddles are set to the lowest adjustment on the top e. The saddle rests on the bridge tray and the action is still too high. On one the bottom e is also affected. Here the saddle is aligned to and rests on the bridge tray retaining screw which prevents adjustment. The nuts on both need filing to remove small nicks which is causing string pop when tuning.
On one the bridge tray doesn't not completely cover the pick up cavity routing. The neck pick up is quite muddy on both and I can't brighten it up with adjustment.
For some reason I enjoy playing them both despite the build flaws. I think the neck radius is flatter than most (I'd guess at 12"radius). I enjoy working on guitars so will use these as modding platforms.
