The OX Stomp Dynamic Speaker Emulator pedal puts a world-class recording studio at your feet, featuring groundbreaking Dynamic Speaker Modelling technology that goes far beyond traditional impulse response systems. Built on the foundation of Universal Audio's award-winning OX Amp Top Box, this stereo guitar pedal offers 22 authentic speaker cabinets, six vintage microphones, and comprehensive studio-quality effects including genuine 1176 compression, plate reverb, delay, EQ, and modulation�all controlled via the UAFX Control app.
What sets the OX Stomp apart is its ability to convincingly emulate speaker breakup, drive, and cone cry, providing harmonics and sonic complexity that's indistinguishable from a perfectly studio-miked speaker cabinet. The pedal is the only effects unit to offer Dynamic Room Modelling with a complete selection of room microphones, giving you the authentic experience of recording your cranked amp in a professional tracking room. This technology captures the nuanced behaviour of real speakers under different playing dynamics, something static impulse responses simply cannot achieve.
Compatible with UAFX amp emulator pedals, popular amp modellers, multi-effects units, profilers, and even your favourite amp's preamp line out, the OX Stomp comes loaded with over 100 curated RIG setups covering any amp type or genre. The UAFX Control app makes it simple to swap cabinets and microphones, fine-tune effects parameters, assign RIG presets, and configure the footswitches for instant sound and effect toggling. With silent switching, buffered bypass, analog dry through, and stereo inputs and outputs, this compact pedal measures just 3.62" � 5.55" � 2.56" and requires an isolated 9VDC power supply with 400mA minimum current.
