I am Looking at the Peavey Ecoustic 112 guitar amp. The intended use for this would be an electronic drum machine. I will also use it for my acoustic guitar and a mic. I have been told by sales staff that it will work great and I have tried it out. It sounds great but, my concern is, if it will stand up to the thumping of the bass sounds. Again I have been told it will but I am having some doubts. Any comments??
