The bridges on the early Combo 400, 800, etc. differed from those on later guitars: they had a wider saddle spacing (2.1" E-E) and 6 saddles of equal height. Our Combo bridges duplicate those features, but in a package that is precision engineered to higher standards than the originals. No warped frames, no rattles, no buzzes, no wobbles. Everything you want from a vintage bridge and nothing that you don't. With the best of both classic design and precision manufacturing, it's the perfect drop-in replacement for your missing, rattling, or buzzing vintage bridge.
