I plug everything into a Furman Power Conditioner and don't have any trouble with the dread 60 cycle hum. Also provides protection if there are any issues with the power at the venue. There are alternatives, but that's the one I use :)

it might be the guitar and/or cable more than the amp.

To troubleshoot whether it's the guitar/cable, you could just turn down the volume knob on the guitar and see if the hum persists. To check if it's the cable, try using a volume pedal to cut the sound before it reaches the amp input. If those all turn out to fail and the noise continues, I'd check preamp tubes first, then start worrying about power supply. I'd personally look into a power conditioner anyway, though.

If it's happening at only that one place, it most likely is the power supply of the venue. Check out http://www.furmansound.com. :wink:

It could be electro-magnetic interference from nearby equipment. Does the level of the hum change as you move around? Are you using single coil PUPs?

you should take fox5150's advice and get a power conditioner if you keep playing there. Also, if possible, make sure you use an outlet far from any fluorescent or dimmed lights.

If the hum is consistent regardless of guitar position or orientation then the hum is coming in on the power cord and a power conditioner will help.

If it's an electromagnetic field and it's coming in your guitar cord, then you can buy the best power conditioner on the planet and it'll be useless for reducing noise, but you will have nice clean power.

I bought the Furman Power Factor Pro and it did... absolutely nothing.. hehe. I still have the
same amount of hum.. and the tone sounds exactly the same. It seems to me to be a big
clunky expensive box with lights.

I had a similar problem (NASTY NASTY HUM) and I ended up going through my rig cord by cord...lots of chords and power connectors. I found the culprit-a bad Pedal power connector and things have been QUITE ever since! Yaaaaaaaaaaaaaaaa!!!!
