Device powers up however,no sound is coming from my bass cabinet
Make sure the volume and master volume are turned up. Try the amp with a different cabinet and a known good speaker cable. If you get sound, it's your speakers or your speaker cable.
If still no sound, you need your amp serviced.

Hi Dan
I wish I could just say what to fix, but you can not do this at home. Line 6 is a great amp and worth the time taking it down to the music shop , to be looked at an give you a repair estimate. good luck keep on rocking in the free world. DFD

The frequency of the A string when in tune is 110Hz.
What you are hearing is actually 120Hz which is the second harmonic of the 60Hz power frequency. It would be hard for you to distinguish between 110 an 120.
Try this test: Bring something that produces a reasonable magnetic field such as a wall wart power adapter that is powered near your pickup... Then you will be able to see that you are picking up stray magnetic fields from your environment.
Humbucker pickups attempt to quash such pickup by winding the pickup so stray magnetic fields cancel in adjacent coils.
Some pickup CAN occur on your cord and also in an amp.
If you leave your cable unplugged from teh guitar you are LIKELY to pick up some of this hum... The second harmonic pickup is COMMON when devces like full wave rectifiers are driven by transformers in the area.

The output stage has a problem. From your description, I'd guess that the high voltage supply has failed. The low volume and distortion suggests that you are trying to power the speakers from the driver section rather than the outputs. There is a resistor that fails in some of this series. If I remember correctly it is either a 2K or 3K resistor 10 watts in size. If you have no experience with repairs, I'd seek a service shop that is familiar with these units. The part runs between $5-$10.

You will need at least a 24 channel mixer to give you spare channels. You also need an active crossover and a snake. The advice you need is too much to include here so I am including some links:http://mixonline.com/live/FixIts/, http://en.wikipedia.org/wiki/Live_sound_mixing, http://mixinglivesound.com/blog/tag/outdoor-concerts/,http://mixinglivesound.com/blog/, and http://www.scribd.com/doc/11435651/Beginners-Guide-to-Mixing-Sound. You may need more monitors than you are planning on and you might consider in ear monitoring.

While it could be true that you're having a problem with the guitar or cable as the previouse expert suggested, to say that it can't be anything else is false. It could be a jack problem...it would only be apparant when the jack is making contact with a cable. I do think you should test it with another guitar and another cable but if that is not solving the problem then I bet it's a problem with the input jack of the amo itself or even one of the ionternal components (this is a digital amp and there are MANY components and settings that can trigger a problem like this) If the problem is not solved with a new cable/guitar configuration then it's time to take it to the shop.
