The B7 vibrato not only adds to the aesthetics of a guitar (a Les Paul in particular), but it adds a whole new dimension of sound to a guitar. Installation was fairly simple with the matching Vibramate adapter plates, however the tailpiece plate did not line up properly with the original strap pin hole, but it was not a problem (just have to push down a tad on the Bigsby).Overall, the vibrato looks great on my guitar. I did not notice a weight difference between having a stop tailpiece and the Bigsby. However, I did notice that the guitar is louder acoustically (unplugged), and I have a bit more sustain now. The guitar fits in its case too, so there are no problems.The only gripe I have about the Bigsby is that for the first week the guitar did not stay in tune for any duration of time. I applied some graphite to the nut and bridge saddles and it seems to have eased the tuning problems. It just takes some proper string stretching/applying graphite to fix the issue. I won't be taking this off my guitar!
