The SV Drums seem to have a remarkable likeness to this tom mount and low mass lugs. the SV Drums use a cast mtg hoop and verticle mtg plate, but the clamp, down to the memory lock, looks identicle - although not as polished. The Gretsch uses rubber grommets to hang the tom, the SV uses lug lock washers to hold the mtg hoop down against the low mass lugs. as of 1/10/12 I still have not found any documentation on the used SV Drums I have aquired.
