Der G-LAB MIDI 4 x LOOP (M4L) ist ein kompakter, MIDI-gesteuerter Effektschleifen-Umschalter, der für die Verwaltung von bis zu vier unabhängigen Pedalen oder Signalketten entwickelt wurde. Er verfügt über einen echten passiven Signalweg mit elektromechanischem Relay-Bypass, um sicherzustellen, dass der Gitarrenton unverändert bleibt, wenn die Loops inaktiv sind. Das Gerät unterstützt sowohl MIDI-Program-Change- als auch Control-Change-Befehle, was eine flexible Integration in komplexe Rack- oder Pedalboard-Setups ermöglicht. Jeder Loop kann auch manuell über Tasten an der Oberseite umgeschaltet werden, und eine integrierte Opto-Element-Schaltung bietet eine "Silent Switching"-Funktion, um hörbare Klickgeräusche zu eliminieren. Entwickelt als modulare Erweiterung für die G-LAB Guitar System Controller oder als eigenständiges MIDI-Utility, enthält es einen MIDI THRU zum Durchschleifen zusätzlicher Geräte.

The G-LAB MIDI 4 x LOOP (M4L) is a compact, MIDI-controlled effects loop switcher designed to manage up to four independent pedals or signal chains. It features a true passive signal path with electromechanical relay-based bypass to ensure guitar tone remains unaltered when loops are inactive. The unit supports both MIDI Program Change and Control Change commands, allowing for flexible integration into complex rack or pedalboard setups. Each loop can also be toggled manually via top-mounted buttons, and a built-in opto-element circuit provides a "silent switching" function to eliminate audible clicks. Designed as a modular expansion for the G-LAB Guitar System Controllers or as a standalone MIDI utility, it includes a MIDI THRU for daisy-chaining additional equipment.

Mac 4.4 Midi

REBEL line Shimmer Reverb stompbox. A hybrid combination of a 24-bit DSP and an analogue signal path results in a clean effect space while maintaining a strong dry signal.  

Spectral Verb is like a ticket into the outer space, and the three potentiometers determine the destination galaxy.  

Everything is safely enclosed in a powder-coated metal housing with a legendary footswitch you can find in other g-lab’s products, which ensures excellent results on the demanding scene over the years.

SV-1 Spectral Verb

The G-Lab GLA-TCH-1 is a classic chorus effect pedal featuring G-Lab’s Max Analog technology, which achieves a clear and deep chorus effect on electric guitar and bass. This dual-effect design houses a 24-bit DSP processor with a discrete analog signal path and control, resulting in a very low-noise, low-distortion sound.
