Guild 302A Bass Guitar Broken Neck Repair

The Guild 302A , a unique vintage bass.

This Guild 302A bass was brought  into the workshop with a split in it’s headstock. This presented a fairly routine repair. It was to be a visible fix because of budgetary constraints.

During the course of the repair it was decided that the existing Badass bridge should be removed and an original BT-4 bridge be installed. The chances of finding a BT-4 were fairly remote and the original for this bass had been lost several years ago. However, with much internet searching and to the great surprise and delight of the owner a second hand BT-4 was located for sale in the U.S.

On receipt of the new BT-4, the Badass bridge was removed and the old style bridge installed. The frets were polished and fingerboard cleaned. All the electrical components were overhauled and cleaned. The bass was fitted with new Rotosound strings, the truss rod adjusted and the string spacing and intonation set.

What resulted was a unique vintage guitar restored to it’s former glory.

Apparently only 500 of these basses were ever produced.

Guitar Repairs: Electric Guitar Intonation








Electric Guitar Intonation

A simple test by ear can reveal if the intonation is set correctly. This check will be made easier if the guitar has been fitted with new strings.

* Check the harmonic at the 12th fret by lightly touching the string and sounding the note.

* Now play the note at 12th fret, if the latter sounds sharp or flat compared to the harmonic an adjustment is needed.

* A more accurate assessment can be made by using an electronic guitar tuner.

How to adjust

If the played note is sharper compared to the harmonic, the string length will need to be lengthened. Locate the string length adjustment screw on the bridge, rotate clockwise to lengthen. Repeat this process until the harmonic note and the played note correspond.

If the played note is flat compared to the harmonic, the string length will need to be shortened. Locate the string length adjustment screw on the bridge, rotate anticlockwise to shorten (could differ depending on manufacturer). Repeat this process until the harmonic note and the played note correspond. Read more…
