Tune

From Teach-Me-To-Tattoo-Wiki

The act of making a tattoo machine run the way the artist intends it to run. Some machines are tuned to run fast, while others are tuned to run slow. A coil machine can hit hard or soft as well.

Some artists will tune the machine by visual means, while others will use sound.

Recently there has been an influx in digital readout power supplies that will tell the artist the Follow Through and Duty Cycle as well as the Voltage. This is supposedly to help the artist tune his / her machine.

While other bettors who bet on sports online does seek help from this artist.
