I am trying to test out a new pedal (alpha omega omicron) which requires the pickups (passive bass) to be wide open. However my amp (Kustom KXB100) is EXTREMELY loud even turned up barely a hair! It’s driving the family crazy and there doesn’t seem to be anything on the amp I can adjust to make the volume lower. I am a relatively new bass player and 100% new to effects and pedals.
