So i have an roland cube 80x amp. It makes a little white noise all the time, even if my guitar is turned of. When i play something, the noise goes louder along with what im playing. I have the amp on a chair an half meter beside me, so the noise is easy to hear. Is this normal?
well if it's a dimmer one that you can tweak to adjust the brightness of the bulb then yes, don't ask me the how's and why's but it makes the amp buzzy/fuzzy

however if you don't and just have a normal on/off switch then you might have a wiring issue, unless you have the volume and gain maxed out in which case buzzing/fuzzing is kind of to be expected really...
Try plugging it into a surge protector, that's usually the cheapest fastest fix. Does it still happen when you unplug your cables?
