I have a PRS Mira. It has 22 frets, push pull coil tone control, 3 way switch, locking tuners just like a Mira s2 model. But it has a core series serial number written on the back of headstock, also inside the cavity. This guitar was made right before the Mira S2 model came out in 2013 at the stevenson Maryland plant.They call it a transition model which was made in May of 2013. This also labeled inside the pickup cavity. It has the original core series PRS American pickups and wire harness. I have info to back this up . Prs customer service told me it is a core series mira based on the serial . It's about 6.8 lbs . Very good condition. PRS bag. 1200. Or Trade for the right Gibson Les Paul studio, or a ltd ec 1000 deluxe, guitars should be lite weight, g great condition.
