Summary: Don't waste your money on this amplifier. I ordered one in October 2011 as a Christmas gift for my grandson. I did not open the box to inspect because there were no signs of trauma to the box. When my grandson opened it, the manufacturer's box was also pristine and gave no indication to what he found when he took the amp out. The top of the amp was cracked and the front of the amp was smashed in.
Summary: When I received the amp it the front panel holding the speaker was dented in. Apparently the little blocks that keep the panel in place had been dislodged because they had only been placed in there using glue which I think was not applied properly. I thought that I could fix it and I did but when I turned it on and played it against all the other amps it was not as loud as it should be considering it is supposed to me 400 AMPs.
Summary: was stoked with the price come new opend it up was really happy turned it on turned master and reg volume all the way up and wanted to cry my acoustic guitar un amped was louder was kinda upset then adusted the trble and such and got a lot louder still not 400 watts rms is 60 maybe i have a drive cd200r witch this pyrmid barley beats and the drive is only a 20 watter this amp thoe is not all bad dose pretty well with lo volume bands was pleased that had a line out option...
Summary: When the amp came out of the box I was amazed to discover that the volume was turned up all the way. I needn't have worried. The output is so low that you'd have trouble hearing this amp over room conversation. I'm hoping that I was sent a defective unit, and have returned it for a replacement. I will post another review after the replacement unit arrives. But if this is the best it can do I say stay away from it.
