Classical music on a guitar amp isn’t what the purists do. But this riesling is your opportunity to try. The distortion-like acidic zing, the acetone smear that’s a whisker from blowing the woofer. Suddenly the citrus bloom is an explosion. The chalk blares with all its puckering abrasiveness. Toastiness fierce enough to toast you. Suddenly the palate is alive, live in your living room, vital in a way the composer actually intended.
