Ever wonder what those really nice, expensive preamps you see every now and again can do for you aside from helping you get rid of unnecessary money? Just ask Sister Hazel's Ken Block. He recently added an Avalon preamp to his Takamine acoustic guitar rig, and he sings the praises about the differences (not literally -- he usually sings somewhat metaphorically about life. . . which can be good).

If you're looking to get your acoustic guitar competitive with your standard rock equipment, this one's for you.
