I don't know the specifics of the equipment we're using, but we've got my friend's PC (The computer works very well; his guitar comes out beautifully), this little TASCAM USB mixer, a Shure instrument mic and my amp (An Ibanez Soundwave 100). We've tried micing the amp, we've tried running it through the amp directly into the computer, we've tried plugging the instrument right into the computer. Every time it comes out really clipped and with way more treble than it should, given my amp settings and the way it sounds coming right out of the amp. What are we doing wrong? What COULD we be doing? Thanks!!!
