If I set *all* knobs fully to the left or anti-clockwise, ingluding volume, gain, whatever, *all* of them, it stills hums and hisses.

When I turn the gain knob to two, the sound distorts.

Well, I looked up some reviews and many of the reviewers complain about the same problem.
I plan on taking the thing apart soon and having a look inside at least.

Thanks for the responses.

The amp is new, but it is also a present from a family member.  If I could have returned it I would have done so already.

The hum and noise are present on all channels even when all controls are set at 0.  The distortion channel becomes distorted as soon as the gain was turned to 2 on my guitar. It becomes perceptibly worse when the headphones are plugged in.

Hello everyone!

I recently bought a Fender Frontman 15R.  The moment I turned the thing on it began to hum and emit other sorts of white noise.  This was particularily noticeable while using headphones.  I was told that I could remedy the problem by installing an "RF shield over the circuit board".  I suspect any sort of conductive material should function properly but I really have no idea as to where to begin, so any help would be appreciated.

Thanks!
