Acoustic Guitar Bridge Reglue

The bridge truly is the heart of an acoustic guitar. Typically made from a piece of wood such as ebony or rosewood, it is glued to the guitar’s top, where it serves several critical functions. When strung to pitch in standard tuning, a set of light gauge acoustic guitar strings exerts about 160lbs worth of tension upon the instrument. Since the strings are attached to the bridge, this pulling force is partially transferred to it. Though guitars are designed to be able to resist that force, if there is any weakness in the glue joint connecting the bridge to the top, it can fail.

Vintage Acoustic Guitar Pickguard Replacement

Many acoustic guitars manufactured from the late 60’s through the mid 80’s utilize acetate or celluloid plastic pick guards glued directly on top of bare wood. An unfortunate concern with this technique is that, with age, the pick guards have begun to shrink and degrade. This is similar to another common affliction of vintage instruments: The breakdown of plastic tuner buttons. As many of these instruments have attained a degree of collectability far above the manufacturers wildest expectations, expert repair is often warranted to save these fine instruments.

Though they can be made from many different materials, for this article, we will be focusing on the process of hand cutting a new acoustic guitar saddle out of a piece of bone.

Replacing Crumbling Vintage Tuning Machine Buttons

Shrunken, crumbly, plastic tuning machine buttons are not uncommon on vintage instruments. As it ages, plastic breaks down. This makes the plastic brittle. Eventually, the tuning machine’s buttons deteriorate to the point that they can no longer hold up to the pressure exerted upon them from normal use. If forced, they may fall apart entirely. This can make restringing or even simply tuning the instrument impossible

Relicing Guitars: Making New Look Old

Relicing is a term used to describe the various processes used to make new parts or instruments look old. Though it may sound simple, when done properly, the job is far more involved than simply throwing some dirt and scratches onto a piece and calling it a “relic”. At its best, it is a detailed simulation of the aging process by professionals who have studied and documented the aging of vintage guitars.
