J-45/50 Bridge Plates


Recommended Posts

Piggy-backing off of some of my earlier threads.

I know and have a lot more about dates/specs of many things such as pickguard shape and color, bracing, bridge shape, etc. These all help ID a guitar.

Question is: Do bridge plates change much over the years? Did bridge plates get larger after the year 19--?

Builders generally made changes to solve an engineering problem which more often as not dealt with warranty issues.  So not surprisingly Gibson bridge plates varied over the decades.   The bridge plates in something like an early-1930s L-00 was after thin compared to what you would find in an LG2 built just some ten years later.   

Generally though, Gibson abandoned the traditional size bridge plate when they moved to ADJ saddle bridges so by 1961.  Earlier if you are talking about the J45 on which that bridge became an option in 1956,  Gibson obviously felt they needed something more substantial to support the tops beneath those heavy bridges.  The plates they went to were fashioned out of plywood  and large enough to qualify as a piece of furniture.  By the time you get into the 1970s the plates were so large they could fill the entire area between the two X braces.
