Universal Audio UAFX OX Stomp Dynamic Speaker Emulator
OX Stomp brings the speaker and cabinet side of the OX Amp Top Box to a pedalboard. Dynamic Speaker Modeling reproduces how a cabinet and room behave as they are driven, which is what most impulse response loaders leave out, so an amp emulator stops sounding flat at the output stage.
Studio effects run after it: 1176 compression, plate reverb, EQ, modulation and stereo delay, all configured from the UAFX Control app. Connections are 1/4 inch unbalanced in and out with stereo capability on the second jacks, and USB Type-C handles registration and firmware. The UAFX Control app adds realtime MIDI control, Bluetooth and hardwired connections, and footswitch modes with presets on tap.
