"The Nextone is our most realistic and tube sounding amplifier range. It has the 4 most well-known and classic amplifier sounds built-in, and the modern input/output connectivity that a guitar play would require. This is the amp I always recommend for those that do not want to sacrifice that tube amp sound but are sick of the unreliability and weight of lugging one around. The Nextone is our most traditional sounding amp, plus you can even be your own Amp Tech when using the amazing Boss Tone Studio. It comes with a 3-year warranty when registering your product with Roland Backstage.”

Overview by GAK 

The Nextone Stage is a 40W 1x12 Combo Amplifier. It has 4 analogue Class A/B power amp circuits, driven by a Class A/B power amp, which you would find in the most efficient valve amplifiers.

You can select between 4 legendary/iconic American and British amp/valve types (6V6, 6L6, EL84 and EL34) and even select one to be your clean, and then another to be your crunch/lead tone. Each of these 4 models gives the same dynamic response and signature tone that these 4 amps are originally famous for. These can be independently selected for clean and crunch channels, allowing you to personalise your dream amp setup. 

The sound engine within the amp is Boss' legendary TubeLogic, meaning that every component of the amp from jack to speaker, has been meticulously modelled and replicated. When you select a specific amp type, everything from the gain, EQ and effects will react exactly as the physical amp would. TubeLogic also allows playing expressively and dynamically with the amp, as the modelling will behave just like a traditional valve amp, softening/cleaning up as you play guitar or drive/breakup as you attack/dig in. It even reacts differently when switching the guitar you are using with a Nextone, meaning each of your guitars maintain their own voice and individual character. Not only that, if you are playing at bedroom volume, you can reduce the total power of the amp to just 0.5 of a watt, meaning you can still experience the tone of a dimed amp. but at a reasonable volume. 

The Speaker has been designed to perfectly partner and interacts with the 4 Class A/B power amp circuits, meaning it will project the full tonal capabilities of these amps. It reacts exactly the same as the most popular Green, Silver and Blue type speakers. If you already have your favourite speaker setup, simply unplug the speaker from the back of the amp and connect the Nextone via a Speaker cable to your cabinet (single 8ohm or dual 16ohm).

The Nextone has a dedicated input for the option GA-FC footswitch, a Rec Out (which has cab simulation meaning you don't need a mic), a Line Out for connecting to PA and an effects loop.

Connect the amp via USB to your computer and it will record as it's own Audio Interface. You can also use the dedicated Boss Tone Studio software opens up a whole new world of options for your Nextone. You can customise how the amp reacts at the preamp stage, the power amp stage, what effects are enabled and fine-tune the amp with a versatile EQ. BTS essentially makes you an amp engineer, personalising the amp to your optimum setup.

The Boss Nextone Stage Guitar Amplifier. Four Power Stages, Unlimited Expression.

Combining classic tube sound and feel with next-generation tonal diversity, the BOSS Nextone series presents an exciting new concept in professional guitar amplification. Distinctive channel voicings deliver a wide range of inspiring tones, while four selectable Class AB analogue power amp types provide instant access to the unique characteristics of 6V6, 6L6, EL84, and EL34 output tube sections. Backed by our advanced Tube Logic approach, each power amp type re-voices the entire circuit from input to output, putting the complete sonic experience of these signature power stages in one amp for the very first time.

Want to dive deeper with even more sound customisation? Just connect to the Nextone Editor and become a virtual tech, fine-tuning bias, sag, EQ, and other internal settings to perfectly match your individual style and touch. Nextone also includes convenient modern features for stage playing, such as built-in effects, a line out for mic-free direct tone, and power control for expressive cranked-amp sound at manageable volumes. And thanks to Tube Logic, you get to enjoy all the great sound and response of your favourite tube designs without the backbreaking weight and ongoing maintenance hassles.

Next-Generation Guitar Amplification with Tube Logic: Widely acclaimed by guitarists everywhere, the Tube Logic design approach delivers real-deal sound, feel, and response by reproducing the complex interactive behaviours of tube amps in every way. This comprehensive process also brings valuable advantages for today’s players, including greater reliability, reduced weight, and maintenance-free operation. Tube Logic evolves even further with the Nextone series, unlocking access to deep tone customization features that are impractical or impossible with traditional tube designs. A Nextone amp puts the true response characteristics of the most famous amp designs at your fingertips, allowing you to tweak your sound with unmatched precision.

Instant Power Amp Re-Voicing: In a tube-based guitar amplifier, the preamp is important for basic tone shaping, but it’s the power amp design that really defines the overall sonic signature and playing feel. Most amps use a specific output tube type, while a rare few allow you to swap out different power tubes. Unfortunately, this process usually requires physical tube replacement and bench time with a tech, making it expensive and inconvenient. For the most part, you really needed to buy multiple amps to access the unique tonal characteristics of different output tube sections…until now.

Nextone changes all this with the ability to instantly re-voice its analogue Class AB power amp section with one of the four classic designs. American sounds are represented with 6V6 and 6L6 output tube types, while British sounds are represented with EL84 and EL34 types. Unlike modelling amps, which simply feed pre-cooked amp models through a non-reactive amplifier, selecting a power amp type on the Nextone physically changes the complete output circuitry, as well as the way the preamp and speaker interact with it. This makes the entire amp perform authentically at each setting, providing the realism that’s only possible with the advanced Tube Logic approach.

Nextone Power Amp Types:

  • 6V6—Found at the heart of many legendary low-wattage American amps, the 6V6 output tube is known for its distinctively sweet, crisp tone and organic compression.
  • 6L6—Used in classic American stage amps and some modern high-gain designs, the 6L6 output tube delivers a high-headroom punch with a round and full midrange character.
  • EL84—Famous as the power tube in British combo amps introduced in the late '50s and early '60s, the EL84 produces glassy, clean chime at lower volumes and rich, creamy distortion when cranked.
  • EL34—The power tube found in the iconic British stack amps, the EL34 is loved for its warm, fat tone and unmistakable rock crunch.

Cranked Sound and Feel at Lower Volumes: With any tube amp, you really need to push its output tubes to get it to sing at its best. Unfortunately, this means turning up the volume, which is nearly always frowned upon by sound engineers, bandmates, and neighbours. Driven by Tube Logic, Nextone delivers the complex distortion characteristics of output tubes and their interaction with the output transformer and speaker, providing that rich, dynamically responsive sound we love. And with Nextone’s adjustable power control, you can always experience this cranked-amp tone while matching the volume to any situation, be it home, studio, or stage.

Be Your Own Amp Tech and Customise Tones for Your Style and Touch: Nextone features a dual-channel design with clean and lead channels plus a shared three-band tone stack and presence control. Boost and Tone switches are on hand as well, allowing you to add some extra gain and sparkle if needed. With a quick button press, you can switch the amp into the custom mode, which provides factory-tweaked variations of the standard clean and lead channels. Better still, the custom mode channels can be fine-tuned to your liking with the Nextone Editor software.

Via a friendly interface, the Nextone Editor gives you deep editing tools to refine the sound to perfectly match your personal style and favourite pedals. Set a channel’s tone stack to American or British types, shape the overall tone with a powerful channel EQ, and even tweak the playing response by adjusting bias, sag, and more. The Tone switch can be assigned to two different types, and the Boost switch can be set for different characters or even be assigned as a compressor. A system-wide EQ is available too, enabling you to define the tonal balance of the entire amp. And with 99 different user setups available, you’re able to customise Nextone’s sound for every gig you play.

Onboard Effects and Switchable Effects Loop: With its built-in delay, reverb, and tremolo effects, Nextone brings even more versatility and convenience to gigging guitarists. Using the Nextone Editor, the delay section in custom mode can be freely assigned to analogue, tape, or SDE-3000 delay types or a tremolo effect, while the reverb can be assigned to plate, spring, or hall types. Furthermore, each effect type offers a deep set of parameters for dialling in the perfect tone. The amp also includes a loop for integrating your own effects, with series/parallel operation, loop position, and more selectable via the Nextone Editor.

Practical Features for Performance and Recording: Connecting with just a single cable, the optional GA-FC foot controller provides a command centre for channel selection, Tone, Boost, effects, pedal volume, and more. If you want to travel even lighter, up to three FS-series foot-switches can be used to control various functions. There’s also a line out for sending a direct signal to a PA, plus a phones/recording output for silent practise and tracking sessions. Using the Nextone Editor, the character of the direct sound can be set to one of three Air Feel settings for a range of mic’d cab tones.

External speaker jacks are included too, with support for connecting up to two 16-ohm 4x12 cabs for even bigger tones. In addition to providing communication with the Nextone Editor, the amp’s USB jack functions as a direct recording interface for your favourite DAW software. Multiple channels are supported, allowing you to record both a cab-emulated output and a dry direct tone for re-amping later through the Nextone.
