Hi,

I have an old yamaha rbx250 bass, and I've lost the truss rod setup
tool. This bass uses a hex socket wrench instead of the usual allen
wrench, so I can't use my usual tools.

Does anybody know what size is the yamaha wrench?

TIA,
Javier.

Measure the hex nut...in mm.

Why not e-mail Yamaha and ask them the size or buy a wrench?

Have you tried phoning your local distributer for Yamaha musical products? I
had a BB1100s once and had the same problem, they mailed me one for nothing
after a quick chat on the phone. If the truss key for the RBX is anything
like the the BB1100s' they are a type of thin walled socket, similar to a
section of pipe beaten over a hex-shaped former one end, with a hole for a
tommy bar at the other. The tommy bar also had one end shaped into a
cross-head screwdriver IIRC.
Yamaha, the Swiss Knife of truss rod tools ;)

Would have done that... if there was any way of doing it without
removing the neck.

That's the one :)

(do you have the wrench? Can you measure what size is the hex socket?
The local yamaha dealer is less than customer friendly, so I think I'll
have to buy at the hardware store)

Can you push some modelling clay down onto the hex head and use that as a
guessing stick?

Most Tool shops/stores have sets of small sockets, usually with (say) a
quarter inch square driver to fit them.

Otherwise do what most say - get hold of Yamaha or a dealer - come to think
of it where did you buy the thing? Take it back.

That's a good idea.

I'll probably use something like that, go to the hardware store and
guess.

Second hand. Seller doesn't have the tools.

I'll see what the Yamaha dealer has to say, but, if my experience with
them in this country is any indicative, I'll end up buying at the
hardware store :)

Sorry for the late reply Javier. I've checked my toolbox but I must have
given the tool away with the bass when I sold it. From memory I think it's
1/4" (or 6mm Metric) size but the important factor is the outside diameter
of the socket, which is why most standard sockets will not fit. If you are
unlucky trying to trace a suitable socket and you have access to a lathe you
could try turning down a regular socket to fit inside the cavity on the
bass.
Good luck!
