Hi Kerry, Aside from the unlikelihood of being able to physically get the tuning tool on the bottom pin row and have enough swing room to do the deed, I think it's pretty slick. I can't really tell from the photo, but it looks like (and seems reasonable that) the socket in the tuning wrench is oriented something between 45° and 90°, so it can be flipped over to get an effective eight point bite from a four point wrench, for that reason. An eight point socket at half that angle offset would be even better. How did the mechanics of turning pins go? Ron N
