Vox VT40X Modeling Tube Guitar Combo Amp 40W
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.
To improve the feel and fidelity of their amp models, Vox decided to go the hybrid route with the Valvetronix+, combining digital modeling with a poweramp section that is driven by an actual tube. This practical method of melding two technologies helped give the amp improved fidelity and dynamics, getting ever closer to accurately representing the behavior of tube amps.
The latest amp to come from this line is the VT40X, which features updated modeling algorithms that sound closer to the real thing than ever, thanks to the utilization of a real tube. The poweramp section is driven by a 12 AX7 tube, which works in conjunction with 11 (up to 20 with software editor) distinct amp models and 13 effects that you can tweak, mix and edit to taste.
Nick Guppy said in his Music Radar review, "There's no real secret to this; they sound superb".
With its combination of digital modeling, analog tubes, and affordability, Vox VT40X is currently one of the best modeling amps available.
We highly recommend the Valvetronix VT40X, for its great balance of size, versatility, tone and cost. For further information see The Best Modeling Amplifiers: Vox VT40X.

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.

Most of the high ratings are from users who are impressed with the amp's overall tone, which they commend as a big upgrade from their other modeling amplifiers. One user put it aptly, saying that many of the amp models are "spot on", which is impressive considering the amp's price tag. A lot of users reported using the Vox VT40X in both practice and small venue performances with great results. Even Music Radar was impressed enough to give it 5 stars, and said that "The VT40X's sounds have really improved with more focus and detail". Unfortunately, Vox can't please everybody, as evidenced by a few users who found the sound to be a bit on the muddy side. One user reported getting better results after he replaced the speaker and the 12AX7 tube.
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.
