This is the UAFX OX STOMP. It's a cabinet simulator. It has a wide variety of built-in cabinets, microphones, EQ, and compressors, allowing you to create sounds for any genre. You can also adjust detailed settings from devices like smartphones. It's useful for home recording and line output in live performances. You can connect one output from your amp simulator to an amp and the other to this OX STOMP, sending the line output to the PA. This allows you to use the sound you created at home in a live setting while still enjoying the sound of your amp. - Model Name: OX STOMP - Function: Dynamic Speaker Emulator - Control Knobs: Drive, Storage, Mic 1, Mic 2, Rig - Input/Output Terminals: Input, Output, Speaker, Bypass - Power: 9V DC, Isolated - Switches: A, B Standing on the shoulders of the award-winning OX Amp Top Box, the OX Stomp Dynamic Speaker Emulator pedal brings the sound of a professional studio, filled with authentic guitar cabinets, microphones, room modeling, and high-quality effects, to an "amp-in-a-box" modeler.
