i bought my fender strat 2 monthes ago and i heard from a friend of my dads whos been playing all hes lifw that after 2 monthes you should go to the store and have the truss rod be adjusted.....well was he right? and could this be the reason why its going out of toune every time i overbend?
depends on the climate/temperature or string gauge that you're using. Truss rod isnt the main culprit for loss of tuning. Only adjust them when your neck relief is off.
It's more likely new strings that haven't been stretched properly, old strings that are dieing or strings poorly wound at the machineheads....whatever the problem is it won't be the truss rod.
