Musiclily Basic 4mm 六角トラスロッド調整レンチ アーレンキー ボールエンド 中国製アコースティックギター用(2本セット)

Bought them for a sound hole truss rod adjustment on an Ovation guitar. Access to the truss rod nut is through the sound hole. The short end is too short to reach the truss rod nut. The long end is too long to fit into the sound hole through the opening in a top brace. Might be okay for headstock truss rod nuts but not for sound hole access.

Work

Too long for me (says "Fender") Good quality just too long for me

Fits perfectly my 88' American made Strat truss rod hex hole.

I got these as I have a Mexican made Strat. Size is perfect for it to sit snugly in the end of the truss rod. It would be good if you could buy just one, but at least I have a spare one now.
