QME-50 Multi Effects Processor with Looper & Amp Models

All-in-One Effects, Amp Modeling and Looper for Guitar, Bass & Acoustic

The QME-50 Multi Effects Processor is a compact, pedalboard-ready unit that brings together 140 digital effects, 40+ amp models, an integrated looper and an expression pedal. Designed for electric guitar, bass, acoustic instruments and even keyboards, it delivers a flexible sound-shaping platform for studio work, rehearsal and live performance.

Inside the QME-50, white-box digital modeling technology recreates the behavior of classic amplifiers and pedals by simulating real electronic components, giving you consistent, characterful tones. You can run up to 9 effects simultaneously and arrange them in an editable effect chain, building your own custom signal paths. With 198 presets (99 factory and 99 user), you can store complete rigs for different songs or styles and recall them instantly in preset mode, or treat it like individual pedals in stompbox mode.

The processor operates at 24-bit / 44.1 kHz, with a high-performance A/D/A converter and a signal-to-noise ratio of 110 dB for clear, low-noise sound. It includes 40+ guitar/bass/acoustic amp types, 38 factory cabinet IRs and support for 15 user IRs, plus 50+ effects covering dynamics, drive, EQ, modulation, delay and reverb. A built-in looper offers up to 90 seconds of recording time, while the drum machine provides 100 patterns for practice or solo performance. Connectivity includes 1/4" stereo outputs, a 1/8" headphone output and a 1/8" stereo aux input for external audio.

The integrated expression pedal lets you control parameters such as volume, wah, pitch or effect depth in real time. A built-in chromatic tuner supports fast, accurate tuning on stage. The QME-50 also functions as a USB audio interface, enabling stereo audio streaming to PC or Mac, and it comes with an intuitive computer editor for deep editing, preset management and IR loading. The metal chassis and footswitches are designed for repeated live use, and the DC 9V power supply (EU standard adapter included) keeps the unit ready for plug-and-play operation.
