A new standard for effects pedal lovers seeking the ultimate control and tonal transparency.

G3 Atom and G3 mark a new standard in pedalboard effects control. Built on the legacy of our award winning G2, G3 Atom delivers the ultimate in signal path purity with possibilities never before seen in a pedalboard switcher.

Hear your effects as they were designed to sound, unencumbered by compromises inherent in a standard pedalboard setup.

We designed the G3 Atom alongside G3 from the ground up, obsessively testing and retesting every aspect of its design to ensure we delivered the most robust, fully featured, tonally transparent switching system in the world.

G3 Atom is an expression of our passion. We compromised on nothing.

    G3 Atom

    Posted by Sean on 20th Sep 2022

    A damned fine system. Compact, has eliminated the need for an ABY to achieve wet/dry/etc. The features are super. Extremely well built. All connections and switches are solid and durable. The end tone with no fx is the best I've heard. (pretty much exactly like going straight to the amp/amps) With FX the tone is also the best. Joe and Lizzie are the best as well - great support! It's a good unit!!!

    Ease of use

    Was so easy to set up straight out of the box! Versatility is amazing for a small unit, ie stereo pairs, tuner/aux loop etc. clean and quiet.

    There is much that could be written about the Atom. The obvious build quality, the simplicity of operation, the clarity of the elements that use a menu, the ability to achieve relatively complex set ups with ease, the midi operation. I could go on. However, thing that impressed the most and makes my purchase an absolute winner is the fidelity. For something that does not make a sound it’s made he biggest improvement to my sound. Just love it and I would not be without it.

    G3 Atom

    Posted by Chris Davies on 6th Apr 2021

    I've had the G3 Atom for about a week now and I can already see just how much this changes things for me and the incredible opportunities it offers. Firstly, the basics. This is a robust product, clearly built to last and I have no concerns about exposing this to the gig environment when gigs are actually allowed again (please let me gig again!) it's so easy to program just from the inbuilt menu I haven't even needed to try the app yet. However I want to focus on the deeper functionality, because that's where the magic is for me. With a push of a button not only can I turn on/off several pedals and change presets by midi, but I can also move my Hall of Fame reverb from end of chain to the front of the chain to fill out the sound of the modulation in the verse and at the chorus, another push of the button moves the Hall of Fame back. With another preset, at the press of the button I go from having modulation effects in series, to having them in parallel with blend control. I could go on, and this is just the stuff I've found in week one. To summarise, the Atom is the brains and centrepiece of my board and I can't imagine it ever not being there. I know the price is a big commitment, but I think it's worth every penny. Great job team

    What a game changer!!

    Posted by Rick E. on 14th Mar 2021

    Always wanted a switching system on my pedalboard, to prevent tap-dancing. For me the G2 was too large and the QuaterMaster doesn't have all the options of the G2... And than there was G3.. and the ATOM!! Exactly the shape I like, enough options with regards to loops and all the functionality of its larger brother. Combined this with Evidence Audio SIS cables and redesigned my pedalboard. Above all with regards to TONE! The combination of good cables (yes, thats a no-brainer) and a switching system that is allowing the guitar, pedal and amp to show its real colour... OUT OF THIS WORLD. I am sorry I haven't made this change earlier. Thanks THE GIGRIG, for creating this piece of art. Regards, Rick Engeringh The Johnssons
