I won this on Yahoo! Auctions (shop), but I tried to adjust it myself. However, even when I turn the truss rod nut, I immediately feel a "click" or "crack" (it's very stiff), or it doesn't turn at all. → I suspect the rod has already reached its maximum tightening point (tension limit), but there might be other causes as well. When I press the neck in the back-bow direction (with a force of 70-80kg) while tightening the rod, there is a reaction, but there's no further reaction beyond the back-bow shown in the image. (It doesn't react any further, it doesn't bow any more.) When I completely loosen the rod, there's a slight forward bow. The edge treatment of the fingerboard and neck wood joint is poor (there's a step on the entire edge, and it catches. The worst areas are at the joint). ※ Currently requires repair. #FERNANDES #Fernandes #FernandesRevolver #REVOLVER #Revolver #FR #FR65 #FRSeries #GuitarNeck #24FretNeck #GuitarParts #GUITARPARTS
