GELABS is a free multimedia application developed by Shenzhen MOOER Audio Co. Ltd for iPhone. It offers a brand-new mobile experience for musicians and guitar enthusiasts. With GELABS and a compatible audio interface, users can access 171 amp models and stompboxes, as well as MOOER's proprietary MNRS (MOOER Nonlinear Response Sample) technology.

One of the standout features of GELABS is the MNRS technology, which allows users to sample tones from their real-life amps, cabs, and effects pedals. The MNRS engine 2.0 analyzes the tonal qualities of the sampled equipment, creating a higher-order nonlinear model that accurately replicates the same tonal characteristics and feel.

Additionally, GELABS offers MOOER Cloud, where users can upload and download preset patches. The MNRS Project allows users to upload and download sample files, which can then be exported to their GE series multi-effects pedals for an immersive experience.

With a library of 171 high-quality effects, including preamp models, cabinet simulators, power amp simulators, and stompboxes, GELABS provides unlimited possibilities for creating unique guitar tones. The app also features 12 different microphone models and supports dual-microphone mode in the cabinet simulation module.

GELABS is compatible with iOS and iPad OS operating systems, as well as various audio interfaces and MIDI controllers. It also includes a built-in drum machine, tuner, and virtual footswitch support. The global settings menu allows for easy toggling of EQ, cabinet simulation, and power amp simulation settings.

Overall, GELABS offers a comprehensive suite of features for guitarists, allowing them to explore a wide range of amp models and effects, while also providing the ability to sample and replicate their own gear. It is a must-have tool for any guitarist looking to experiment and create their own unique sound.
