Since I just got a 6120DE with Dynasonics and didn't know where to start with the pole height adjustments on the pickups. This made a big major difference in clarity for me. I couldn't find anything here on adjsuting teh pole height specific to Dynasonics. This was located somewhere on the other Gretsh site is not all that easy to search and I coudl not locate it. I thought I'd pass this on. A great big thanks to Paul Setzer for getting it to me.
