Hex wrench tip for bass necks with 24 fret extension

[kimbass]

Bass necks with the 24 fret extension make it impossible for normal sized hex (allen) wrenches to reach the truss rod nut, but if you'd like to be able to adjust the rod with the neck attached, a T-handle hex wrench (in my case, the Klein Tools JTH4E12, about $6 at Amazon) with the handle removed works like a charm -- of course you also need to lengthen the access rout.
