Vox Valvetronix Plus VT20+ 20w Combo

The Vox Valvetronix range of amps was hailed as the great happy medium between solid state and tube amps - taking the advantages of both and combining them into an amp that sounds warm and authentic yet is easy to maintain and retains the features the modern guitarist needs.

The new Vox Valvetronix Plus amplifiers take the next step with a greater range of models and features, and updated amp models that sound more accurate and faithful than ever before. The Valvetronix+ amplifiers are the new faces of versatility in the hybrid amp market. 

Here's what Vox say about the VT Valvetronix+ Range

Introducing the new Valvetronix+ Series - the latest in Valvetronix evolution, featuring 99 ready-to-play presets, a massive infusion of effects, plus an all-new Power Level control

Of the broad lineup of VOX amps - from large all-tube amps to mini transistor amps - the Valvetronix Series is acclaimed by the broadest range of musicians and is being used in the widest variety of musical scenarios today. Delivering the perfect fusion of great tube amp sound and cutting-edge modeling technology, the original VOX Valve Reactor circuitry made its sensational debut in 2001 as the guitar amp for the new century. Since then, it has undergone continual renewal in response to the latest developments in amps, and in order to flexibly meet today's needs. Now in 2010, the Valvetronix series is once again powerfully and dynamically reborn, offering a larger number of highly evolved amp models than ever before. From the convenient and portable VT20+ to the dual-speaker VT120+, the new VALVETRONIX+ Series delivers the guitar sounds sought after by discerning guitarists of every style.

Tube-powered VOX Valve Reactor circuit

Every guitar player seeks the power and playability delivered by a tube amp; the fat drive tone, wide dynamic range, subtle picking nuances, and quick response. After painstaking analysis of guitarists' tastes and preferences, VOX has focused on the importance of the power amp circuit in creating the sonic characteristics long sought from tube amps. The VOX Valve Reactor was developed out of this power amp philosophy. Based on a 12AX7 vacuum tube, the Valve Reactor circuit at the heart of every VALVETRONIX+ Series amp perfectly reproduces the operation, subtle nuances, and tonal character of a real tube-powered amp.

More amp models than ever before

The new VALVETRONIX+ Series boasts an amazing collection of 33 distinct amp models - a new milestone for Valvetronix amplifiers. In addition, the VALVETRONIX+ represents a giant leap in quality. The preamp EQ features Bass, Middle and Treble controls for precise tone-shaping. Beginning with classic VOX amps such as the AC30, the diverse amp model selection continues to encompass coveted amps from the pages of history, as well as the latest high-gain amps, providing a sound selection that spans the ages. Call up the sound of an old favorite, or experiment with amps you may never have tried - sought-after amps played by your guitar heroes, rare boutique amps, and vintage amps - and pursue unexplored sonic paths.

25 Diverse, high-quality effects

One of the best features of VOX modeling amps is the ability to combine the built-in effects with the onboard amp models to create a complete and powerful sound. Just as with the effects, the VALVETRONIX+ Series makes no compromise when it comes to effects, boasting a level of quality that rivals top standalone units. The broad array of effects is divided into two sections: Pedal effects such as distortion, wah, and compressor; and Modulation/Delay effects such as chorus, flanger, and tape echo. In each section, there are 11 effects to choose from. Featuring easy-to-use settings, you can simultaneously select the effect type and adjust its parameters. In addition, there are three types of Reverb (Room, Spring, and Hall). With the addition of Noise Reduction, up to four different effects can be used at the same time.

99 Preset programs

The musicians at VOX have put together 99 preset programs, expertly voiced and ready for immediate use. Each of the 33 amp models provides three presets: Basic, Effected, and Song. An Effected preset calls up the correct combination of  effect type and setting for a particular style.

Song presets are just like Effected presets; each one is a faithful recreation of the signature sound used by a famous guitarist to perform one of their classic tracks. Of course you're also free to edit any preset - or start from scratch with the manual setting - and save up to eight of your own custom sounds to the User presets.

Beyond the numbers

One of the greatest advances from previous Valvetronix models is the astounding sense of power generated by the VALVETRONIX+ Series. The power amp section has the potential to significantly exceed the wattage value indicated by the model name - as indicated by the shaded section of the Power Level knob. The new VALVETRONIX+ Series also feature a newly re-voiced VOX original design speaker that is sure to amaze you with a powerful sound that you would not expect from a chassis and speaker of this size. These fine VALVETRONIX+ amplifiers genuinely deliver sonic power that cannot be expressed by mere numbers.

Seize the power

The sense of drive produced in the tube power stage is what defines the inimitably fat and warm tone that's at the core of a great guitar amp sound. Our tube-driven Valve Reactor circuitry is at the heart of recreating this sound. Volume, Gain, and Master Volume controls provide key levels of controlling your gain to achieve a wealth of clean, overdriven and distorted sounds. In addition, these new VALVETRONIX+ Series amplifiers feature an altogether unique Power Level control. By lowering the Power Level, it's possible to achieve high levels of gain and distortion at any listening level. And, as was mentioned above, reserve power can also be dialed in using the Power Level control when you really need your amp to scream. The Power Level control allows you to take full advantage of the VALVETRONIX+ Series potential in any situation.

Convenient and versatile input and output

The headphone out jack can also be used as a direct line output. This output is equipped with the simulated response and character of a speaker cabinet, so you'll enjoy the natural spatial sense of playing through speakers, even when using headphones or when connected to a mixer or recording system. Plug your CD or MP3 player into the AUX input jack and enjoy jamming along with your favorite songs. In addition, the tuning function needed by every guitarist is built in, eliminating the need for a separate tuner.

Optional VFS5 footswitch operation

Plug in the optional VFS5 footswitch is connected, and use your feet to switch programs, turn the reverb and other effects on/off, and control their speed, providing additional options for sonic creativity and live performance power.

    Speed of service excellent

    Anonymous review via Feefo | Purchase date: 18 November 2014

    Brilliant piece of kit for rehearsal, recording, or live gigs in small venues. (br/)Amp 'models' are extremely close to the original sounds and the inbuilt effects are stunningly good. (br/)Have tried my 80's Telecaster, 1955 reissue Strat (bought from Anderton's), and original 1962 Burns Vista Sonic with this amp and it delivers the goods. Probably the loudest 20W amp I've ever heard. (br/)Every guitarist should have one of these!

    Absolutely love this amp

    Martin | Purchase date: 21 April 2013

    Wow what a great amp, the Possibilities to create your own tones and mimic your guitar heroes tones on this amp are endless. Go to the vox web site and see the listed tones from others user of these amps and try them out. I would urge anyone on a budget but wants a great sounding amp for home/practice use to try one of these out.

    Tim | Purchase date: 23 June 2012

    Having had the amp for a month now it still haven’t had time to really try out all of the settings, mainly due to the fact that I find the settings that I have tried have been so good I just end up staying with those.

    Each of the effect options are convincing in their sound and are easy to tweak with the addition of Tap tempo and further dials to add depth etc.

    A great addition to the home practise set up and would highly recommend it.

    Mattis | Purchase date: 28 September 2011

    It took a while to get here (UPS, customs, got lost for a bit, yada yada) but damn it was worth the wait!

    I haven't owned a guitar amp in 8 years. Used to own a Roland Cube that I never loved that suddenly died, and been using Line 6 Pods for more than 10 years and always return to the AC30 model. When I started researching amps, I really wanted a good AC30 sound (crunchy cleans yay!). I tried a Fender Mustang which was nice and the VT80 which I felt had more personality. Always wanted a VOX, and now I have one!

    Great styling, fairly easy to use. All around good sounds, especially the breakup sounds. I'm not into the heavier stuff, and I feel they're never as fat as the real thing (used to play a Marshall stack ages ago). This amp is surprisingly loud and great sounding! I play it at probably 1-2Watt and it's easy to keep the neighbours and family annoyed by adjusting the power level. I guess you could gig with this if the drummer isn't too heavy handed.

    Only negative so far is that the chicken head switches don't match up to the labels 100

    Mr. shaun payton | Purchase date: 22 June 2011

    quality sonuding amp for the money

    Mr Graham Cleaver | Purchase date: 14 February 2011

    OMG What an Amp! I use a marshall JCM stack for gigging but wanted an ultra light portable amp for working out songs at other band members houses but pokey enough to compete with an electronic drum kit, bass and keyboards. Wow - don't mess about looking at other Amps - just go and buy the Vox.
