Do Hanika guitars have truss rods? Or are they built like Spanish guitars? Or something else…?PM, USA, 6th April 2021
They don’t have truss rods – although the necks are reinforced for stability; the neck is not joined to the body in a “Spanish Heel” so the answer is “something else”.
The body is fitted with a neck block which is rebated in 3 dimensions to take the heel extension and the block attached to the underside of the fingerboard. Here are a couple of pictures –
Incidently, you can see the neck reinforcement – in this model a rectangular cross section piece of ebony – running down the back of the neck and into the heel extension.
