As a part of the scene that became legendary in the Late -80:s through the -90:s known to the world as “The Gothenburg Sound” ZUTA is now Introducing the revolutionary & ultimate guitar amplifier for the most discerning musician:

Behold the “GBG120” Tube Amp

It’s our all Analogue 19" rack-mounted Tube Amp, 3-Rack units high. And the best part? It's only 7,8” (20 cm) deep, 120W powerhouse! Taking you from the 1950:s to the 2050:s in a flash!

With its Ultra compact design sporting 4-Channels, each featuring separate Gain, Volume, and EQ controls, and multiple Console-style Mode switches that are illuminated in different colors for visual feedback in any environment, so that you always can see what you're doing – even in the darkest of venues. You'll be able to dial in the exact sound you're looking for in no time! You can be sure that your sound will be as clean, soft, sweet, delicate, funky, sparky, crunchy, rocking, powerful, expressive, and aggressive as you are. The GBG120 is super responsive and organic. We have worked super hard not to sacrifice the Clean Sound on the expense of the Ultra High Gain capabilities, this was only made possible through implementing four different Pre-Amp topologies all working together inside this AMP!


Unlike other amplifiers that can take up a lot of precious stage or studio space, our amplifier's slim design makes it the perfect choice for any musician who needs a powerful and versatile amplifier that won't take up too much room.

But our amplifier isn't just compact – it's also packed with features that will blow your mind. With a solo section for added versatility active on all 4 channels, and a built-in addressable gate per channel to help you achieve the perfect tone with zero noise, our amplifier is unlike anything you've ever played before. And with both serial and parallel loop options, you can easily incorporate your favorite pedals and effects into your setup.

Let's not forget about the tubes – with 12AX7 tubes in the Pre-amp section, 6L6 and EL34 tubes in any combination in the Power-Amp section. You can achieve that rich, warm, and dynamic sound that only comes from tube amplifiers. And with our quality that is “Beyond Boutique” Amps, you can trust that this amplifier was built to last and to deliver the performance you would expect and need in the most critical of situations like on a live stage or in a hot session in the studio cutting your next track.
