Magnetic & traditional dent removal

We use the Magnetic Dent Removal System (MDRS) to remove dents from areas that ourtraditional tools will not reach without unsoldering joints. It is a great addition to our collection of tools, and especially effective on large brass and saxophone bows.<

Polishing Raw Brass

We can hand polish (without buffing) raw brass or raw nickel instruments. Any instrumentthat is not lacquered will eventually become tarnished. This is an un-lacquered french horn that sat for about 15 years. After Ultrasonic cleaning and hand polishing, it came right back to life.

Ultrasonic Cleaning

Ernie Williamson Music Repair Shop is the only shop in the area equipped with a 90 gallon Ultrasonic Cleaner. Ultrasonic cleaning is an innovative method of cleaning musical instruments through the use of high frequency sound waves and a biodegradable, environmentally friendly cleaning solution. Transducers mounted in the tank create tiny bubbles which clean and scrub the entire instrument in a safer, more thorough manner than traditional mechanical or chemical cleaning methods.
