Help! Yamaha Acoustic Guitar Truss Rod Adjustment

[yjibhoii]

 
meron po akong 1973 Yamaha FG-151 Acoustic Guitar, pano po ba ina-adjust yung ganitong klaseng truss rod nut? mataas po kasi action.. wala po akong makitang tutorial sa youtube or kung kahit saan.. ibang klase po kasi yung itsura niya.. salamat po sa mga magrreply..

ganyan po yung itsura niya..

Bakit mataas ang action? Gawa ba ng bowed neck (underbowed?).

Kailangan lang sir i-adjust ang truss rod para istraighten ang relief ng neck. Not really to adjust action per se.

Kung straight naman ang neck, di niyo kailangan galawin ang truss rod. Kung straight siya at mataas ang action, ang kailangan ayusin ay height ng saddle and/or nut slots.

Assess muna. Pero regarding your query, mukhang pwede jan yung "pipe style" na wrench... parang pwede rin ang screw driver (flat)..

oo, mataas yung action, hindi straight yung neck eh.. may bow nga.. walang problema yung saddle hindi ko kelangan i-shave, wala naman masyadong hump yung body..

sinubukan ko yung socket wrench, nagkasya naman, kaso hindi ko lang mapihit, sobrang tigas..

same problem here..i also have a Yamaha FG-251 MIJ acoustic guitar with the same t-rod..i guess ,a guitar luthier ang kailangan natin for this problem..im sure meron silang proper tool for this type of t-rod.

na-research ko na.. i used an 8mm socket wrench to tighten the truss rod.. kaso ang problema, parang wala paring nagbago..  siguro kelangan na i-sand down yung saddle and bridge..

pero kung wala ka idea para mag adjust ng tension ng neck at pumihit ng truss rod may be you need a luthier para makasigurado ka...

Personally, I'd take that to a Luthier.  From there, he would tell me how to fix it.  At least the next time I encounter it I'd know what to do.  learn from them they know what their doing
