Varieties
Since its invention, different versions by Gibson and other companies have emerged. Gibson has introduced at least three versions that have minor differences in construction:
- Standard Tune-o-matic is the first version that appeared in 1954. It used slim posts, but lacked slots for adjustment with screwdriver. The only way to adjust it was using a thumbwheel that was accessible only after loosening strings. Adjusting the bridge height required retuning of the whole guitar.
- Modern Tune-o-matic is the second version. It featured a much larger post with a threaded pot. It could be adjusted using a slotted screwdriver instead of a thumbwheel, but the posts were too large to be used in Fender guitars. It also required drilling to install.
- Refined standard Tune-o-matic is the third version of the Tune-o-matic. It featured both slim posts (as in "standard" version) and a screwdriver adjustment (as in "modern" one).
There are multiple widely known Tune-o-matic models that differ in the following parameters:
