Holy crap, did I just figure something out?
When I record guitars in my bedroom there is a ton of extraneous ground hum coming through my amps. I always put it down to using too many pedals and too many cables and all that, but back in March I recorded using just one amp and no pedals and still had a lot of noise. I didn’t think it was my amp, I just thought there was something else going on.
It literally just dawned on me what it is! It’s the overhead lights in the room!
When I record in my little guitar nook I have the laptop running on battery. I’m one plug short of being able to cover everything I need, so battery it is. I was just thinking to myself that maybe it’s time to get an adapter with two plugs so I don’t have to worry about it anymore. The plug closest to where I sit now has my USB audio interface in one socket and a lamp in the other. I thought, I could just unplug the lamp while I record and plug it back in when I’m done because I usually turn on the super bright overhead lights and that’s when it hit me.
The overhead lights are on a dimmer switch. Hot Damn, why didn’t I think of that? Dimmer switches are the noisiest bastards in the electrical world (I don’t know if that’s true or not, but lets just go with it) and they are the bane of many a professional recording studio’s existence! Also, there are three lamps in the room that all have smart bulbs. I bet those kids are noisy as hell too! I bet if I turn off all the lights I won’t have as much 60 cycle hum coming through my amplifiers! I bet!
I mean, I’m probably wrong, but who cares! I feel smart right now, just let me enjoy it for a while.
