Aside from being available in different finshes , this one being chrome, they have essentially the same features. This one most likely is made of milled aluminum. The Hipshot site says they have adjustments for variable string spacing. This is a standard bridge without a piezo element offered on some models. I hope this helps, I dont have the original box or instructions, I dont recall if it even had any as I bought it several years back. It has never been out of its original packing so its like brand new. Heck, it could even be chrome plated brass for all I know, I honestly dont remember.
