Universal Audio UAFX OX Stomp Dynamic Speaker Emulator

Universal Audio UAFX OX Stomp Dynamic Speaker Emulator

OX Stomp brings the speaker, cabinet, mic and room emulations of the OX Amp Top Box to a compact pedal, to be used after amp emulator pedals, preamps or modelers. Dynamic Speaker Modeling reproduces speaker breakup, drive and cone cry, and more than 100 curated RIGs cover different amps and genres.

The cabinet library includes 1x10, 1x12, 2x10, 2x12, 4x10 and 4x12 models based on classic American and British combos and cabinets. Studio-quality effects include UA 1176 compression, plate reverb, EQ and stereo delay (dual, crossover, ping-pong). Mics, effects and footswitches are set in the UAFX Control app via Bluetooth or USB, with silent switching, buffered bypass, analog dry through and MIDI over USB.
