„CHUCK gives me the best of both worlds: the tube tone and playing feel of a multi-channel amp, plus the flexibility of a digital modeler – with no noticeable latency when playing and no slipped discs when hauling gear. When it comes to road-readiness, I don't know of any comparable product either.“

„I think the CHUCK looks incredibly sleek and it fits perfectly into my home studio. With the CHUCK I can record professional-sounding guitar tracks at home without spending ages tweaking.“
Bronte Klippell
baby of the bunch
PROUDLY. UNDERDOG.
„Every guitarist should try CHUCK. The tube tone delivers the depth and dynamics you need, and the digital effects give me the control I need in the progressive world. Add to that how easy it is to use – a well-thought-out complete concept for stage and studio.“
Daniel J. Fries
Daniel Fries / AFFECTOR
PROUDLY. UNDERDOG.
„I play everything stylistically – from soft to loud, from folk to metal. For me, CHUCK is the tool that keeps up with that whole range without compromising on tone. An amp I can rely on live and that delivers the right sounds just as quickly in the rehearsal room.“
Dedi Bepunkt
Kill your Neighbours!, Double D & Friends, Vitamin Bepunkt, Dedi & The Covid Hunters, Die Notnägel
PROUDLY. UNDERDOG.
„CHUCK gives me full tube tone in pedalboard format – including the effects to match. Thanks to the studio software, I can dial in my presets exactly to what I need. This is exactly the kind of setup I searched for for years.“
Dennis Biest
Silver Linings
PROUDLY. UNDERDOG.
„If you're looking for a flexible, compact all-in-one package for every situation, and you don't want to get lost in a thousand menus but instead get to really good sounds fast, there's hardly any way around CHUCK. And on top of that: the tubes look damn good glowing, too.“
Dominik Hellmuth

PROUDLY. UNDERDOG.
„CHUCK wins you over with its rugged design, easy handling and its gutsy tube tone – an ideal companion for live shows.“
Fabian Luther
Escape the Madness
PROUDLY. UNDERDOG.
„During the studio production, CHUCK was a problem-solver, a fun-maker, and exactly the right extension of our sound for me!“

„CHUCK is built to be rugged and completely road-ready. Its powerful tube tone cuts through beautifully in a live setting and delivers maximum presence at all times. Thanks to its versatile tweakability, I can shape exactly the sound I need in any situation – precise, punchy and reliable. On top of that, it fits seamlessly into my live setup. Made in Germany rounds out the whole package.“
Johannes Ritter

„The most compact tube preamp with genuine tube feel and built-in effects.“
Mad Steex
Modern Rock / Metal
PROUDLY. UNDERDOG.
„I liked the sound with the two tubes right away. The easy operation would do a lot of pure modelers some good, too. You don't need a degree and to have dug through thousands of submenus to find a killer sound. For me it's an all-round worry-free package that lets me play every gig without lugging a ton of gear. Pedalboard with the Chuck on it, two guitars, done.“
Mario Betz
Band Facelift
PROUDLY. UNDERDOG.
„CHUCK has become my go-to guitar amp in the home studio. Switch it on and start playing. I only need three good sounds to be happy: clean, crunch and lead. And I've found them. Sometimes I'll still put one of my pedals in front, but other than that, that's it. From now on it's just playing and creating. That's how it should be.“
Matthias Kahra
Forced To Mode
PROUDLY. UNDERDOG.
„For me the Chuck is the perfect home studio tool: uncomplicated, great-sounding and always reliable. With my own IRs I find my sound in no time – that's exactly how modern guitar gear should work.“
SOLACE
Modern Metal
PROUDLY. UNDERDOG.
„CHUCK delivers lively sounds with genuine tube character while being incredibly easy to use. Great sounds are dialed in within moments, even without an editor or software.“
Stefan Manarin

PROUDLY. UNDERDOG.
„I first heard CHUCK at MetalCon in Berlin, and it had my attention right away. I was impressed by how convincingly it combines real tube technology with digital flexibility in such a compact unit. It delivers exactly the sounds we play in Unverkalt, while being incredibly easy to use and to take anywhere. It quickly became a fixed part of my guitar setup.“
