My volume knob doesn’t affect the instrument’s volume. What’s going on?

The ETHERWAVE's VOLUME knob is a tuning adjustment. Its purpose is to adjust how the instrument's volume changes as your left hand approaches the volume antenna. This knob is not a 'volume control'. That is, it does not simply make the tone louder or softer. It should not be used to set the instrument's maximum volume. The volume control on your sound system is used for that purpose.
