what would cause a annoying hum when pedal is on

Are you using a wall power supply or battery? The power supply could be injecting a 60 Hz hum. Try a battery and no power supply. If there is no hum, replace the power supply. If there is still hum, check your cables, switches & pots in your guitar and then your amp. Still hum after all that, the pedal is probably bad.

not sure exactly, but have you tried using a different cable and/or mic to see if the hum goes away? perhaps one of them is faulty.

Hi, A hum is typically a ground issue resulting from a wiring problem with the outlet into which you've plugged the amp. It could also involve any effect pedal you're using. The amp itself should be dead quiet unless you're playing--it's a digital device, and a hum is analog. Unless the amp is defective, it's likely that a hum comes from somewhere else in the signal chain. You might try plugging the amp into an different outlet or power strip, trying your guitar through a different amp at a music store, or trying another guitar through your amp. This is a good amp and Fender wants you to be happy with it. Don't be shy about switching things around to isolate the problem, or asking for repair/replacement if the amp is found to be defective.

The one I purchased did have digital sounding hum/buzz in the background. I returned it and saved up for an ac15c1c.

Yes - mine squeals (ordered October 2014), I'm pretty sure it's an inductor or similar on the inside. Only occurs when a device is plugged in (so when the DC/DC inside is actually under load).

Consider the size affords moving to an area where spurious electrical signals would be minimal. Use an outdoor extension cord to move as far from any building as possible. If the noise continues then the problem is from the internal electronics. If the hum is gone then the problem is coming from the area where you normally use the Bose. You need to find what the problem source is by turning off all the electrical apparatus near to the unit.

My turntable does not have a hum. A feedback hum is produced through the system at loud volume but that's my fault because I have it sitting on a hollow cabinet, my cartridge is really sensitive and that's the exact same thing as a supersensitive stage mike...I expect the feedback hum. But there is no hum from the motor or anything on the turntable itself

You're experiencing ground loop hum. Try using batteries only. If you still here loud hums, send it in for repair.

Sounds like you have a ground issue somewhere, I haven't experienced any hum or distortion

Have you tried switching your cable? I've never gotten any humming when playing this, either through a tube or solid state amp.

Have you ruled out a ground loop as the source of hum? http://www.youtube.com/watch?v=4YM1iwC6vhg http://en.wikipedia.org/wiki/Ground_loop_%28electricity%29

Mine does a light hum, as the airbags, inflate, not loud at all, yours sounds defective

A hum that you can hear is normal. If it is loud, something is wrong. If it is noisy without a load connected, I would replace it. Are you sure you have not overloaded it?

Mine also hums but just when setting there, as soon as I turn on the radio on the humming quits. It did hum one time and all I had to do was turn off then back on.

It has an audible high pitched hum. Very annoying if you are too close to it or if you have sensitive hearing.

It sounds like you must have a defective unit. I don't get a hum with either tubes or solid state amp. Sorry yours is making bad noises.

The noise is not loud, instead it is an audible hum. It does not go away and really is a great white noise. After a while you will forget it even hums.
