Orange Amps has made a splash at NAMM 2025 with the announcement of the O Tone 40, a new 40-watt Class A/B combo amplifier designed for both practice and small gigs. Amp designer and technical director, Ade Emsley, proudly introduced the amp, highlighting its surprising volume and versatile tonal palette.

O Tone 40

The O Tone 40 boasts a clean, 40-watt Class A JFET front end coupled with a Class A/B 40-watt output stage, driving a single 12” Voice Of The World speaker. Emsley emphasized the amp’s ability to deliver “ludicrously loud” volume when needed, while also maintaining excellent tone at lower levels, making it ideal for practice.

Tremolo

The amp features a straightforward control layout with bass, middle, treble, volume, reverb, and a bias-wobble analogue tremolo. The footswitchable tremolo offers a vintage vibe with modern convenience, while the digital spring reverb adds depth and dimension to the sound. A buffered low-impedance effects loop allows players to seamlessly integrate their pedalboards.

The O Tone 40 offers a direct output for studio recording and direct connection to a PA system for live performances.

With an affordable street price of £329/$399, the O Tone 40 is positioned as an accessible option for a wide range of guitarists.
