Universal Audio Ox Amp Top Box for Electric Guitar

The Universal Audio Ox Amp Top Box is a reactive load box designed for electric guitarists. It lets you play and record your tube amplifier at ideal volumes and tonal sweet spots, allowing you to do so at levels commensurate with not annoying all of your loved ones or neighbors. Oftentimes, getting the desired tone out of a tube amplifier involves cranking the volume to levels undesirable for living-room studios or small venues; with this device, you can achieve that just-breaking-up tube tone—or even full-on crunch—at lower levels. You can lower the signal hitting the cabinet with the speaker volume knob, while the line-out knob and headphone knob control the levels of their respective destinations. This load box can switch between 4-,8-, or 16-Ohm operations to suit various cabinets.
