The Tube Driver is said to be equivalent to the classic Ibanez Tube Screamer. In addition, with the toggle switch you can select "normal" and "boost" modes to choose between a clean boost and cranked-up tube-style distortion. The manufacturer calls it a "classic blues overdrive sound." We call it the final proof the good things come in small packages. The Tube Driver sounds as meaty as any spit roast and will impress anyone whose intention is to rock out real damn hard.
