The Sanken 2 Crossguard Saber, from Pach Store, features a standard arsenal of lightsaber sounds including: turning on sound, turning off sound, idle hum, swing sounds, lockup sound (activated by tapping the button twice), and clash sounds (upon impact with something).
You can also access a mute function by holding the button for a few seconds before tapping the on button to activate the saber. To restore the sound, turn the saber off and then hold the button for a few seconds until the saber makes a sound. Then tap the on button to activate the saber again.
