AI guitar amps, smart multi‑effects, and a budget hummingbird acoustic

Guitar gear is changing fast, and AI is now right in the middle of it. This week’s standout releases range from a stage-ready AI amp you can literally text your tone into, to a pocket-sized multi‑effects unit that runs Neural Amp Modeler (NAM) profiles. There’s also a happy accident turned fan‑favorite boost pedal, a serious update to a legendary multi‑effects box, and a surprisingly affordable acoustic that skips all the tech.

A $400,000 mistake that became an $89 boost

Sometimes a huge mistake turns into a product people actually want. That’s the story behind the JHS Fumble, a compact clean boost born from what’s been called the biggest error in the company’s history.

Back in 2025, JHS released a DIY kit called “Not a Dumble.” It was supposed to include a clean buffer based on a rare Dumble loop device. Instead, the wrong circuit went in: a Dumble BBC 1 design that had been reverse‑engineered for John Mayer in 2019. That circuit itself turned out to be a clone of a 1970s Barcus Berry acoustic preamp.

The Fumble is essentially a production version of that accident. It’s a JFET clean boost with two controls: a master output and an input knob that simultaneously trims bass and input gain, tightening up everything that comes after it in your signal chain. It runs on standard 9V DC, draws very little current, and is built in Kansas City.

Do most players need another clean boost? Probably not. But the mix of JHS, Dumble lore, and John Mayer history makes it a fun, story‑driven pedal at a relatively low price point. It’s the kind of thing you’d happily borrow or grab if you love the backstory as much as the tone.

Eventide H9 Harmonizer Gen 2: studio algorithms, finally usable on a pedalboard

The original Eventide H9 became a staple on pro pedalboards for its high‑end algorithms, but its single knob and tiny screen made deep editing painful without an app. The new H9 Harmonizer Gen 2 aims to fix that while keeping the sound quality that made the original so popular.

The Gen 2 model adds a 2.5-inch color display, three dedicated quick knobs, and extra buttons for bank, select, and performance controls. That means you can finally edit delays, reverbs, pitch shifts, and more directly on the pedal without reaching for your phone or laptop.

Under the hood, Eventide has moved to modern ARM-based processing and packed in over 74 algorithms, including the full H90 and H9 Max libraries, plus support for more than 1,000 presets. Their high-fidelity SIFT technology powers advanced engines like PolySynth, PolyHarmonizer, PolyFlex, and Prism Shift, giving you studio-grade pitch and modulation options.

The pedal is designed for both stage and studio use, with line and instrument level I/O, flexible routing, spillover between presets, a built-in tuner, USB‑C connectivity, full‑size MIDI, and expression pedal support. Bluetooth control isn’t active yet but is planned in a future update.

If you want compact access to Eventide’s classic and modern algorithms in a format that’s finally easy to edit on the fly, this is a serious contender, even if it sits at the higher end of the price spectrum.

Powering hybrid boards: Walrus Audio Canvas Power HP Plus

As pedalboards get more complex, power supplies have to keep up. The Walrus Audio Canvas Power series focuses on clean, high-current outputs, and the Canvas Power HP Plus is built specifically for hybrid rigs that mix traditional pedals with a power‑hungry modeler.

Each output on the unit delivers up to 500 mA, which is plenty for most pedals. The standout feature, though, is a dedicated high‑power output that can be switched between 9V and 12V and delivers up to 3A. That’s enough to run popular modelers like the Line 6 HX Stomp, Neural DSP Quad Cortex, Boss ME‑series units, Eventide H90, and others.

The HP Plus also includes USB‑C power and a built‑in meter to show how hard the supply is working, so you can see at a glance how much headroom you have left. It ships with the adapter cables you need for common modelers, making it a tidy one‑box solution for modern boards.

If your core sound comes from a modeler but you still love analog drives and modulation, a power supply like this can simplify your setup and reduce noise issues.

Positive Grid Reactor: the AI guitar amp you can text into existence

Positive Grid is best known for its Spark practice amps, but with the new Reactor series it’s stepping onto the stage. These are real wooden‑cabinet combo amps (50W or 100W, 1x12) that bring AI directly into the live rig.

The headline feature is what Positive Grid calls AMP Intelligence AI. Instead of only turning knobs, you can create tones in three unusual ways:

• Text‑to‑tone: Describe the sound you want in natural language, and the amp builds a full signal chain around it.

• Audio‑to‑tone: Upload a recording, and the amp analyzes it to generate a matching amp and effects setup.

• Image‑to‑tone: Provide an image (for example, a photo of a classic amp or album cover), and the system uses it as a reference to shape your tone.

Underneath the AI layer, the Reactor is still a full‑featured modeling amp. It comes with 24 amp models, 27 effects, an effects loop, 5‑pin MIDI input, and a USB‑C audio interface for 24‑bit/48 kHz recording. You also get eight customizable onboard presets and a built‑in tuner on the front panel.

For players who like the idea of AI helping them dial in sounds but still want a traditional amp form factor, this is an interesting bridge between bedroom practice and live performance. It’s priced to compete directly with popular solid‑state modeling combos from brands like Boss and Blackstar, but with a much heavier AI twist.

There’s a broader conversation happening in music about AI’s role in creativity and ethics—similar to debates around AI music generation tools and even concerns about superintelligence in pieces like Nate Soares’ stark AI warning. In the case of the Reactor, the AI is focused on helping you recreate or discover tones, not replacing players, which many guitarists will find easier to accept.

Epiphone Hummingbird Tribute: classic acoustic vibes on a budget

Not everything this week is AI‑driven. The Epiphone Hummingbird Tribute is a reminder that sometimes you just want to strum a chord and feel the guitar vibrate under your hands, no screens or menus involved.

This model takes inspiration from the iconic Gibson Hummingbird but aims for a much more accessible price. It features a square‑shoulder dreadnought body with layered mahogany back and sides and a select layered spruce top. The mahogany neck has a comfortable rounded C profile and a 24.75" scale length, topped with a 12"‑radius laurel fretboard, 20 frets, and simple dot inlays.

Visually, it stays close to the classic look, with antique‑style binding that helps the finish pop. There are three high‑gloss finishes: Ebony, Heritage Cherry Sunburst, and Antique Natural, plus a left‑handed version in Heritage Cherry Sunburst.

There’s no pickup or onboard preamp here—this is a pure acoustic. One weak spot is the hardware: the tuners look basic despite being described as “deluxe,” which may feel a bit optimistic. Still, taken as a whole, the guitar offers a lot of style and playability for its price and puts Epiphone back into a more affordable segment that’s crowded with brands like Harley Benton and Orangewood.

For players who want the Hummingbird vibe without paying Gibson prices, this Tribute model is a compelling option, especially if you don’t need built‑in electronics.

Mooer GE 100 Pro and GE 100 Pro LI: tiny AI‑assisted modelers with NAM support

The most surprising launch of the week might be the Mooer GE 100 Pro and its battery‑powered sibling, the GE 100 Pro LI. These compact multi‑effects units pack in features that, until recently, were reserved for much pricier gear.

Design‑wise, Mooer has moved to a cleaner, more modern look with a 3.5-inch color display and an RGB ambient lighting strip. But the real interest is under the hood.

The GE 100 Pro uses what Mooer calls MNRS intelligent reverse modeling technology for amp and preamp simulations. More importantly for many players, it officially supports loading Neural Amp Modeler (NAM) sample files, plus third‑party impulse responses. That means you can bring community‑made or self‑captured amp models into a device that’s small enough to toss in a gig bag.

On top of that, there’s a Mooer AI Assistant mobile app that can generate custom settings based on text prompts. You describe the sound you’re chasing, and the app helps configure the unit for you—similar in spirit to other AI‑assisted music tools covered in pieces like this look at an AI-assisted DAW for Suno music.

Feature highlights include:

• 200+ effects models

• 150 preset slots

• An 80‑second stereo looper

• A drum machine with 40 grooves

• Bluetooth audio streaming

• USB‑C for desktop editing and direct mobile OTG recording (acting as an audio interface)

The GE 100 Pro LI version adds an internal lithium‑ion battery, offering up to around nine hours of play time, making it ideal for travel, rehearsals, or quick sessions without hunting for power outlets.

Considering the price point, the spec sheet is impressive. If the sounds hold up in real‑world use, this could be one of the most cost‑effective ways to access NAM profiles and AI‑assisted tone shaping in a truly portable format.

AI and guitar gear: where things are heading

Across these releases, a pattern is clear: AI is moving from the computer into the hardware guitarists actually use every day. Whether it’s Positive Grid’s Reactor letting you text your tone into an amp, or Mooer’s GE 100 Pro using AI to help configure complex signal chains, the goal is the same—make powerful tools easier and faster to dial in.

At the same time, there’s still strong demand for straightforward gear: a simple clean boost with a great story, a refined multi‑effects pedal that finally gets the interface right, and a no‑frills acoustic that just feels good to play.

For players, that means more choice than ever. You can lean into AI‑driven tone shaping, stick with traditional analog tools, or mix both on the same board. As long as the tech stays focused on helping musicians rather than replacing them, this new wave of AI‑infused gear has a lot of potential to make playing and recording more fun and accessible.
