Cable hum

So, I've got some hum in the system, pretty sure it wasn't there yesterday. Where could it have come from? Well... I may have been making some cables today. The thing is as soon as I noticed the hum I started looking back over my work. It was nothing pretty, but everything was in its proper place no wires touching, no streams crossed.

PreAmp Hum

Ok so I bought 2 cheap little ART Media Tube Pre's for about 30 bucks a piece. I had read some suprising reviews about how they were actually pretty good expecially for the price. So a little curious I bought 2.

I actually use mine to warm up my vocals at my live show and the sound is actually very nice and warm.

60Hz Hum Problem

Hey all, please bear with me on this:

I run sound in a small bar/venue, and everything was ghetto-rigged when I took over here. The other day I was in the ceiling running new power cables for the front of house, lights, and an RCA pair from our Yamaha MG20c's REC out to the house stereo so DJs and bands can be heard on the outdoor speakers.

Hum in Guitar Amp/ DI question

Before I purchased the Minimee tube amp I would frequently record a guitar amped (solidstate) and direct by employing a Roland A/B/Y switch routed as follows Guitar to Roland switch A to amp B direct to one of my PreSonus FP instrument channels. This never gave me any problems. When I tried this same routing with the tube amp I encountered an unacceptable level of hum in the amp.
