Question: Musicman Silhoutte 20th anniversary

I am new here, and I have a question for you all.

I was cleaning my father’s garage and found this guitar which seems to be a Musicman Silhouette 20th anniversary. Looking on the web it seems my model is one of those few which came with a Piezo, but I am not sure, thus asking for experts here to confirm my thoughts.

I also wanted to ask if any of you could help me figure out how to adjust the truss rod (i suppose i have to turn the black wheel at the bottom of the neck, but I want to be sure!). I will attach a couple of pics, if you can also confirm me this is a legit one it would be great!

Thanks to everyone for your time, have a good one!
