First I will clarify that I'm a long time guitar player and just starting to learn mandolin. Secondly my mandolin is a Loar F style so very entry level. In any event, I read reviews about the clamp being a loose fit. Sure enough I could not get it to clamp properly. Then I reversed the threaded "L" rods on the wooden block and it clamps down nicely. As for the pickup, I experimented with different positions per the manual and I was picking up a lot of body and/or strumming noise. I then looked at the picture on the box and positioned the pickup per the picture and it worked much better. So wth that said, the sound is OK but not what I would necessarily want to play through if gigging. I would probably mic the mandolin for a better sound.
