The Universal Audio – OX Amp Top Box allows you to play and record your amp at its sweet spot without the need to wake the neighbors. With the best-in-class speaker attenuator, crank up your tube amp to gig levels for that tube saturated breakup while driving the speaker at bedroom volume. Or use the built-in headphone jack to rock silently. Built-in USB makes it an awesome recording rig as well. Ships free off our website, or come down to the store and check it out. We have one hooked up to a Dr. Z head at the moment.
