Hello... my husband is the bassist, not me. He is out of town and our youngest found the amp and messed with it. It is an Ampeg SVT-410HE and he messed with the "level control" ... I don't want anything to be broken when my husband comes home. Do I need to be concerned that our kid fiddled with this? What does it do? I'm very worried something is going to explode when we'rre sleeping or something. Hubby doesn't come home until Friday... and yes I'm planning on telling him what happened, but what do I do in the meantime? thanks for reading, even if you tell me I'm an idiot to be worried.
