Hi, I want to know what is the model of fixed bridge you have on most of your Jackson's Kelly signature model, and what are the advantages of this bridge compared to a traditional fixed bridge. Do you know if it is possible to replace an original Floyd Rose by this bridge without altering too much my Jackson Kelly? I also want to know if this thing is still available, and if yes, by witch brand is it distributed. If not, what fixed bridge would you suggest instead as a good substitute? Thanks for your time, Julien Thibault Ste-Foy Québec, Canada julienthibault@hotmail.com
