Mooer Unleashes the F40i: The Ultimate Desktop "Intelligent" Amp for 2026
Discover the Mooer F40i, a 40W intelligent desktop amp featuring MNRS modeling, a circular touchscreen, and USB-C recording. The ultimate guitar rig for 2026.
The guitar world’s obsession with compact, high-tech desktop rigs just reached a new milestone. Mooer has officially expanded its "iAMP" universe with the F40i—a 40-watt powerhouse designed to bridge the gap between home practice and professional recording.
For years, guitarists have had to choose between the portability of small practice amps and the "grunt" of larger combos. With the launch of the Mooer F40i, that compromise is officially over. Following the success of the smaller F15i, the F40i doubles down on power, features, and sonic depth, positioning itself as the "intelligent" rig to beat in 2026.
Stereo Power Meets MNRS Technology
The F40i isn't just a louder version of its predecessor; it’s a complete overhaul. Pumping 40 watts of stereo power through two 4-inch Hi-Fi FRFR (Full Range, Flat Response) speakers, the F40i delivers a wide spatial image that belies its desktop size.
At its core lies Mooer’s proprietary MNRS (Mooer Nonlinear Response Sample) technology. This advanced modeling system powers 55 onboard amp models and 69 effects, providing a level of realism and "feel" usually reserved for high-end floor processors.
To further sweeten the deal, Mooer has integrated DPE technology, enhancing the dynamic range and making the amp respond more like a traditional tube circuit.
Tactile Tech: The Circular Touchscreen
The most striking visual feature of the F40i is the 1.28-inch circular touchscreen. In an era where many amps rely solely on clunky knobs or external apps, the F40i allows players to swipe through presets and tweak settings with smartphone-like fluidity directly on the unit.
For those who want to dig deeper, the iAMP mobile app provides access to a global community. Users can download GNR (Preamp) and GIR (Cab) files, load third-party Impulse Responses (IRs), and share their custom tones with the world.
A Portable Studio and Practice Partner
Mooer has packed the F40i with "lifestyle" features that make it a Swiss Army knife for the modern musician:
- Built-in Jam Station: 60 drum machine grooves, 10 metronomes, and a 60-second looper.
- Recording Ready: A USB-C port enables OTG (On-The-Go) audio recording, letting you capture studio-grade tones directly to your phone for social media or demos.
- Pro Connectivity: Unique for its class, it features an XLR/1/4" combo jack for microphones or instruments and dual line-outs for connecting to larger PAs.
- Battery Freedom: The F40i Li version includes a rechargeable lithium battery, offering up to 6 hours of cable-free shredding.
Available in Phantom Black, Snowfall White, and Imperial Gold, the F40i is as much a piece of modern decor as it is a professional musical instrument.
