It has a cheap pressed steel case and cheap black plastic knobs, but for the price I wasn't expecting much more.
It sounds a lot better than I had hoped. Midrange is quite delightful the bass is deep, turn the tone control full up and the sound becomes linear, and fully down the treble is almost non existent, so I will leave it in 'neutral' for now and let it run in for a while. On the whole I am very pleased, a real bargain at £29.95. (expert review needed - over to you What Hi*Fi SV)
My problem now is I have to unplug the speakers while using headphones, but I will make a speaker 'kill' switch to get over that problem.
After a bit of research I find it can be improved, and so I will be modding it in the future, this will include disconnecting the tone control and changing the capacitors & resistors. I will also replace the case (I have a blank full size aluminium amp case I got off ebay a while back) I can incorporate the speaker kill switch into that as well.
