I do minor repairs on guitars and basses, including:

Changing strings and tuning

Adjusting the trussrod. This affects the action (string height, buzzing, and ease of play).

Saddle height adjustment for electrics and acoustics. This affects the action at the higher frets.

Intonation for electric guitars. I turn those little screws on the bridge until your guitar sounds much more in tune.

For more complicated repairs, please visit my friend Bill Richardson at Studio Guitar Works.
