It would if the amp is good. But more often than not, I would discourage buying amp used unless the seller could guarantee all the channels are working properly, and the only way to do this would be for the seller to power it up for me to check it myself. I once bought a used amp...then found out later that the left channels were defective. You could get a new amp with a warranty for very little cost on ebay instead. Just my opinion. When it comes to electronics, it is better to buy new when possible.
