Acoustic guitar truss rods need adjustment just like electrics, but manufacturers sure don't make it easy. Access is typically through the sound hole, wrenches allow access to nuts on most makes and models of acoustics, with a precision ball-end tip for easy fit, extra length on both segments of the blade, and an oversized handle for confidence when making adjustments.
