When digital modeling was introduced, the modeled tones lacked fidelity, nuance and dynamics. However, technology has been quickly catching up, blurring the sonic distinction between the real amps from their modeled counterparts.

The Vox VT40X brings with it an interesting combination of tube and digital sound processing technologies, resulting in a hybrid modeling amp with a 12AX7 preamp at its core.

The inclusion of a 12AX7 tube adds to the realism of the 11 built in amp models, just remember that this tube will require maintenance and replacement in time.

It starts off with Vox’ signature chime’y clean, and can go as far up as double rectifier metal tones.

The amp models work together with 13 digital effects that you can configure to your liking and store in its 33 presets, which by default comes with many artist inspired tones.

At 40 watts, this combo amplifier has enough punch for band practice, while the power attenuator control lets you crank the amp at lower volumes.

There’s also a headphones out in case you want quiet practice.

The Vox VT40X amplifier is ideal for guitarists who want to experience the best of both worlds – tube tones and digital amp modeling – at a more reasonable price point.
