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.

Next-Generation Guitar Amplification with Tube Logic

Widely acclaimed by guitarists worldwide, the Tube Logic design approach delivers authentic sound, feel, and response by accurately reproducing the complex interactive behaviors of tube amps. This thorough process provides significant advantages to modern players such as improved reliability, reduced weight, and low maintenance. The Nextone series takes Tube Logic even further, granting access to deep tone customization features that are impossible or difficult to achieve with conventional tube designs. With a Nextone amp, you have access to the true response characteristics of the most renowned amp designs, giving you unmatched precision in tweaking your sound.

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 interacts with it. This makes the entire amp perform authentically at each setting, providing realism that’s only possible with the advanced Tube Logic approach.

Nextone Power Amp Types

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 Customize 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 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 customize 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 center for channel selection, Tone, Boost, effects, pedal volume, and more. If you want to travel even lighter, up to three FS-series footswitches 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 practice 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 favorite 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.
