Eko 2 channels + FX loop + Reverb - 10" speaker - 25W

The essentials to know about the Eko G-BS25 Stealth Black amp

• 25W transistor guitar combo: ideal power for practicing at home and handling small rehearsals.


• 2 channels Clean + Drive: switch from a clean sound to a more powerful distortion via a switch (or optional footswitch).


• 10-inch speaker: compact size, effective projection, and response suited for practice.


• Reverb + effects loop + auxiliary input + headphone output: everything needed to play, record, and practice silently.

An Italian collaboration serving an Eko practice combo

Developed by Eko in collaboration with Italian technician Roberto Tittarelli, the G-BS25 Stealth Black targets a simple idea: to offer an accessible, compact, and reliable transistor guitar combo designed to support the guitarist daily. Within the range, it positions itself as a learning and backup amp: immediate to use, versatile enough to cover several styles, and complete enough to accommodate pedals thanks to its effects loop.

A combo made to progress at home (and beyond)

The G-BS25 is aimed both at the beginner looking for a serious first amp and the intermediate or advanced guitarist wanting a lightweight combo to work on riffs, tones, and timing. Its 25W power and 10-inch speaker make it an excellent companion for home practice, demo recording, and small rehearsals at reasonable volume.

Regarding styles, the "Clean/Drive" logic easily covers pop, rock, blues, indie, and anything requiring a clean tone or a simple crunch/drive setting. The auxiliary input helps you play along with backing tracks, while the headphone output makes silent practice without disturbance possible.

Two channels, 3-band EQ, reverb, and effects loop: essentials well thought out

The interface is intentionally straightforward to focus on essentials without getting lost in menus. The Clean channel features a volume control and a 3-band EQ (Bass/Middle/Treble type) to shape your tonal foundation according to your guitar (single coils or humbuckers) and playing style.

The Drive channel adds a pair of Gain + Volume controls: you adjust the amount of distortion and output level independently, convenient for switching from dynamic crunch to thicker saturation. Channel selection is done via a front panel switch, and the amp also provides a footswitch connection (pedal not included) for foot switching. Finally, the built-in reverb adds air and depth, and the effects loop facilitates integrating modulations, delays, or external reverbs at a more relevant point than the input, depending on your signal chain.

An effective transistor sound: clear clean, punchy drive, controlled dynamics

Thanks to its transistor technology, the G-BS25 delivers a crisp response, precise attack, and "plug and play" usability. On clean, it provides a clear and stable sound, ideal for working articulation, chords, funk/pop rhythms, or slightly bright tones. The 3-band EQ helps balance brightness and body, especially with a 10-inch speaker that favors quick response.

On the Drive channel, the tone becomes denser and more biting: perfect for rock riffs, simple leads, and working saturations that remain controllable at home volume. The playing feel stays direct (less natural compression than a tube amp), which is excellent for improving right-hand consistency and touch control. The reverb, finally, broadens the sound space without adding complexity, for a more inspiring daily sound.
