Guitar Maintenance at Guitar Doctor
Just like any tool, instruments need to be maintained in order to play their best.

The combination of wear and tear, humidity (or lack of it!) and age always cause guitars to become less than best.
Restoration
Guitar Restoration at Guitar Doctor
Either by replacing worn tuners, securing loose braces, properly gluing body cracks or whatever your "experienced" guitar might need, Guitar Doctor can bring it back to life.

The instrument's value may also be enhanced.
This page is not meant as a do-it-yourself guide but as a general description of what could be wrong and what the cure might be.

We can't include everything that can go wrong with an instrument or all of the possible fixes, but this should give all players some insight.

Read below for some common guitar problems and answers or see our F.A.Q. page for more specific answers.

HIGH ACTION

Too much neck relief, nut slots not deep enough, bridge/saddles too high, or any combination of these.

LOW ACTION, NOTES BUZZING

Neck is back-bowed, nut slots too deep, bridge/saddles too low, or any combination of these. May need fretwork to maintain clean playing if you want to keep low action.

ELECTRICS NOT WORKING

Broken connection at jack, faulty switch, short in wiring, poor solder joint, faulty pick up, bad battery in active system.

HEADSTOCK BROKEN OFF OR CRACKED AT NECK

DO NOT TRY TO GLUE IT YOURSELF. This will make it much more difficult to fix in the end.

This is a very common injury, especially with Gibson/Epiphone and more especially with Les Paul models and we see it nearly every week and are able to fix nearly every case, much to the owner’s relief.

The best thing to do to bring the guitar in to the shop as soon as possible.

TREMOLO BRIDGE GUITAR - WON’T STAY IN TUNE OR CAN’T INTONATE

Worn or loose locknut, guitar neck is loose, tremolo bridge pins drifting, strings pinching in nut, too much drag through nut and string trees.

SCRATCHY SOUND WHEN KNOBS TURNED

Controls need cleaning or replacement.

GETS BUZZY IN SUMMER / HARD TO PLAY IN WINTER

Guitar is humidity sensitive and requires seasonal maintenance, especially truss rod adjustment.

May want to purchase in-case guitar humidifier for winter.

PICKUPS HUM INTERMITTENT SIGNAL / CUTS OUT

Poor or no ground connection, single coil p-u 60 cycle noise is accentuated with high-gain amp settings, shielding may be required, hum-canceling pickups may need to be installed.   

PICKUPS SQUEAL / SCREECH

This is microphonic noise and has an abrupt & uncontrollable threshold. Occurs commonly in old and/or single coil pickups. pickups may need to be wax dipped (potted) or replaced

INTERMITTENT SIGNAL / CUTS OUT

Bad solder connection or switch, hot circuit may be touching ground wire somewhere in controls, corroded jack contacts.

VOLUME CONTROL INEFFECTIVE/ CUTS OUT TOO QUICKLY

Control will need replacement or "tone circuit" modification or a linear potentiometer instead of usual audio pot may be desired.

BUZZING / DEAD NOTES ON NECK

This is microphonic noise and has an abrupt & uncontrollable threshold. Occurs commonly in old and/or single coil p-u’s. P-u’s may need to be wax dipped (potted) or replaced

FINGER NOISE ON STRINGS

Strings are old and tarnished or rusted, frets need cleaning & polishing, flat or semi-flat wound strings may be desired.

STRING ENDS STUCK IN TREMOLO BRIDGE

Clamp blocks have been over tightened and are split and spread, locking screws are stripping and jammed from over-tightening.  In standard tremolo bridges, the holes may be too small for the string balls.  Holes will need to be enlarged. 

STRINGS BREAK AT HEAD

String is pinched in nut slot, sharp burr at tension bar, string trees, or holes in string posts.

STRINGS BREAK AT BRIDGE

Saddles worn, sharp burr at saddles or string anchor point. Saddle crown too steep or sharp.

STRINGS BREAK IN MIDDLE

Worn or sharp frets; "ding" in frets - strings too old – more frequent string replacement required.

SIGNAL BREAKS UP

Bad solder connection, faulty switch, hot/ground short aggravated by vibrations in guitar. Weak battery (active systems)

OPEN STRING TWANGS IN NUT

Nut slot too wide, not enough back tension behind nut, nut slot cut too low.

BROKEN OR CHIPPED NUT

This can often be repaired with "dental" style filling and re-cutting, otherwise nut replacement is required.
