Does anybody know if the Yamaha TRBX304 has a single or dual truss rod?
I have heard both scenarios and the TRBX304 Service manual does not mention it.
Also, I have searched high and low on the internet for instructions on adjusting dual truss rods and have not found anything explaining their proper adjustment procedures.
Can somebody point me in the right direction for instructions on adjusting a dual truss rod?
NOTE: My TRBX394 does not need a truss rod adjustment, currently, but as the weather changes I want to be ready with the correct information when it does need adjusting.
I saw your thread and actually it was why I asked because some people say it is single and some say it is double. The Yamaha user and service and user manuals, so kindly provided by howard, give no indication and YouTube has nothing specific to double action truss rods that I could find.
