Hi Brendon, yes it has a struss rod, Godin make a few different multitrac guitars, some nylon some steel. You are right about nylon strings having less tension, but not sure if Godin has a different neck for the nylon "version".

Haven't been working on this monster for a while, ummm er still waiting for the paint to cure!
however I have taken the soft section off the machine heads, so, when I get keen again it's ready to go.
Tried to prise them off but needed to cut them off, but still good.

Rick.

Ps cant resize the photos so will send later.
