So I brought my Y2D in with me for a lesson the other day and besides my teacher commenting on how great it looks he also asked me what that little protruding wheel looking thing is that sits between the neck and the neck pickup. So me knowing nothing about guitars other than if they feel good to me had no answer for him
I figure if he had never seen something like that it must be something weird... so what is it and what does it do? I hope this isnt a completely dumb question
Thanks
