content: 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. Like another reviewer said it was putting out a fraction of the power and sound. I realize I only paid about $70 for it but it was on sale and it retails supposedly for close to $200 dollars. I would have sent it back but the delay in getting a replacement would have unacceptable. I'll buy another amp later and give this one to a friend. Then I'll do what I should have done and gone to a music store and paid a little extra.
