Sara,
Sorry I just saw your question!
Yes, I gave a pair of custom cables with these connectors to Steve Stevens for his use and testing. He told me at the show that he's working on a solo record right now and probably wouldn't have a chance to test the cables for another few weeks. As soon as I have some input from him I'll post it here.
I've used my own cable made with one of these and I really like it. Since finding a bridge for my '67 Epiphone Olympic guitar at NAMM, I've been playing a little more guitar than in the past few years. This thing FINALLY plays in tune! (the original bridge was a fixed-saddle wrap-around with the 3rd saddle set for a wound string. Above the 4th fret you could really tell the difference. Yech!) This is one cool connector!
