Stubby, you're usually my marketing BS indicator, but all stoptails are not interchangeable so how could a trem that takes the place of the stop tail fit all of them? Does it have a lot of side to side slack, or is it adjustable? Also, stretching the strings over the tune-o-matic part, that's asking for tuning issues or string breakage. A roller T-O-M seems like a must with this one.
