This pre-amp was pretty much what I expected it to be.
It's a steal at ?18 including power supply, and even though maybe not being completely amazingly sounding it's absolutely Ok. It makes no noises (make sure to connect all audio stuff to the same "phase").
The box is made from study metal and I doubt you'll be able to kill it without actually trying to. It also got a ground connector which should help you eliminate some noises caused by different ground if you we're to experience some.
The amp also has a stereo-tele output (6,3mm) for use with mixers and other equipment.
