does it always have a hum, or just certain times?  

there are things to do to get rid of hums, number one is to make sure you're using "clean" power and make sure everything is plugged in right.

if it's happening only sometimes, then you could look for a hum filter to put inline.  

however, if it always hums, then you need to think about getting new amps and/or monitors.

does it him using headphones ever?

sometimes a ground lift (three prong to two prong adapter) will help
i use a power conditioner and only use shielded cables. that seems to help me.
peace out!

the hum is continuous and does not happen with headphones.  i haven't tried to power conditioner/shielded cable option yet.

i am interested in whether everyone likes amps or monitors better, as a matter of course.

the best quality for a reasonable price goes with the studio monitors, but they ara not good if you want power just sound quality.
i believe for performance with band a amp would be better, but you personal studio a studi monitor might work, let advise to go to any of those musical instruments and check the sound setting you like better, either a good big amp like roland about 500 or a pair od powered studio monitors like m audio for 250 or some other brands in the same range
it could be that you have the "gain" on your amp too high and the channel volume too low or vice versa.
try adjusting gain and channel volume and see if that makes a difference.  otherwise,  it could be that the amp is not properly grounded.
also, six years later, i know a lot more about ground loops than i used to.

often times the hum is caused by different resistance in the ground wires.  the first thing to do about this is makes sure all your equipment is plugged into the same circuit.  usually this can be accomplished via a powerstrip plugged into an outlet.

the reason for this is that grounds from different outlets, if they are on different circuits, can have different impedance.  basically that means that the signal has to work harder or easier to get to the same place.  if the signal has to do that, then the "extra" signal from the connection that does not have to work as hard will work it's way back to the source. that's how the hum from a ground loop happens.

the other cause is if your equipment has different impedance within itself.  that's why it's important to have good power and sound cables, and if you really want to be sure, make sure your power and sound cables have the same impedance.

however, even then you might not be 100% secure because at times the ground impedance in your equipment will differ from piece to piece. for example, the ground impedance in your keyboard amp might be different than what's in your keyboard.  you can't do anything about this and it usually doesn't cause any problems, but if you get a ground loop hum that you just can't get rid of, try switching to a different amp and seeing if that makes a difference.
