Mark Roffe Need help diagnosing a strange guitar buzz (14) Need help diagnosing a strange guitar buzz 29 Jun 99


Symptoms:

Fretting the high and low E strings at the 3rd fret - > plucking the two strings causes a high, rapid, metallic buzz.
> plucking only the high E causes the same buzz (but only if the low E string is also fretted).

This happens even if my helper muffles all but the high E string. If I fret and pluck only the high E string, and it plays without a buzz, as soon as the low E string is depressed (and not necessarily plucked), the buzz returns. Even if Ginny pinches the low E string so it can't possibly vibrate, as soon as it is depressed at the 3rd fret, plucking the high E string results in the buzz.

Tests and results: 1. Tuning to lower than concert pitch removes the problem. 2. Tuning to 1/2 step higher than concert pitch moves the problem to 7th fret, but with G string and low E string! 3. Tuning 1/2 step low and putting capo on 1st fret removes problem. 4. Loosened truss rod 1/4 turn. No effect. 5. Tightened all sources of potential vibration (tightened tuning machine screws, put strip of paper under and behind saddle, removed endpin, removed truss rod cover plate). No effect. 6. Changed strings to new set of mediums. No effect. Changed strings to new set of lights. No effect. Strings are clipped short at tuning pegs. 7. Dampened strings at nut end, at bridge end, and at tuning pegs. No effect.
