BOSS NEX-STAGE Nextone Stage 40W 12" Guitar Amplifier

The BOSS Nextone Stage is a 40-watt guitar combo amplifier designed to provide tube-inspired response in a portable, maintenance-free format. Its custom 12-inch speaker and analog Class AB power section give players a self-contained amp for practice, rehearsal, recording, and performance. It is built for guitarists who want flexible voicing without changing physical output tubes.

Four selectable power amp types—6V6, 6L6, EL84, and EL34—change the amplifier's response and tonal character from the front panel. This lets a player move between American- and British-inspired output-stage feels within one combo. BOSS Tube Logic technology is used to shape the interaction from the input through the power amp and speaker section.

The Nextone Stage provides Clean and Lead channels, plus Standard and Custom operating modes. Dedicated Boost and Tone switches make it easy to add gain character or brightness from the amp itself. A shared three-band EQ, Presence control, and Master control provide familiar hands-on sound shaping.

Built-in delay, tremolo, and reverb support a compact rig with fewer external pedals, while the send and return loop accommodates favorite effects processors. The Power Control switch supports reduced-output operation for more manageable volume levels. A line output, phones/recording output, and USB port extend the amp beyond a conventional stage combo.

For deeper editing, the Nextone Editor software for macOS and Windows allows compatible settings to be customized from a computer. External speaker outputs provide options for adding properly matched cabinets, and footswitch compatibility supports hands-free control. The Nextone Stage is suited to players seeking a versatile guitar amp that can anchor a straightforward pedalboard, recording setup, or live-performance rig.

Design & Installation

The Nextone Stage uses a portable combo-amplifier format with an integrated custom 30 cm (12-inch) speaker. Its front panel groups channel, EQ, effects, power-amp selection, and power-control functions for direct access. The cabinet measures 492 mm wide, 248 mm deep, and 427 mm high, with a listed weight of 13.4 kg.

Connect a guitar to the 1/4-inch INPUT jack and use the onboard speaker for a complete setup. External effects can be connected through the SEND and RETURN jacks, while optional BOSS footswitches or the GA-FC foot controller can be used for hands-free operation. For external cabinets, use the dedicated 8-ohm or 16-ohm speaker outputs with appropriately matched speaker loads; USB, LINE OUT, and REC OUT/PHONES connections support computer, recording, and monitoring applications.
