Also, when using certain models, the amp can be switched between Class A and Class AB operation. Its unique modeling algorithm actually recreates the analog circuits of some of the most coveted tube amplifiers and allows you to adjust the gain structure and bias of the internal tube in real time. These amps combine sophisticated modeling technology with a multi-stage tube pre-amp circuit to reproduce the unique distortion, touch sensitivity, and the response that is characteristic of classic tube amps. The Gold Drive effect can add sufficient saturation if used sparingly, and the Treble Boost effect works wonders with the AC30 model for Brian May's ultra-thick tone.A potent little combo with in gorgeous British racing green attire.Īs part of the VTX Series, the Valvetronix VT20X is a perfect combination of innovation and tradition. Our Hendrix fantasies are realised by playing a Strat though the UK Rock model with some Univibe, and switching to a Les Paul gives tones ranging from Angus Young to Gary Moore depending on how much gain you use. The new Vox VT+ range is right up there with the best from Line 6 and Fender, so be sure to give them a try. It can sometimes be difficult to see the wood for the trees in the vast modelling amplifier forest. This is a complicated amp, certainly, but never unwelcomingly and it doesn't take too long to find your way around the front panel and come up with some exciting and authentic sounds. As long as Vox continues to make improvements and refinements in keeping with those featured on the VT80+, its modelling future looks as bright as ever. It's worth mentioning that it also sounds good through headphones: good for practise. It may not be quite pokey enough to cut through a loud band at battle volume, but it provides a widely differing array of satisfying tones suitable for myriad styles. The Org Phaser is great with the more subdued amps and, with a high speed setting and a Les Paul's neck pickup, it gives the US 2 x 12 model the perfect sound to recreate the keyboard intro to Zep's No Quarter. UK Metal is the most for modern styles as it provides a balanced mix between sheer low end and high gain treble, and it's probably no surprise that Enter Sandman is among the song choices for this model. The higher gain models are always great fun to play with, and the VT+ provides more than its fair share of dynamic sag and spongy pick attack. Their authenticity does depend on what guitar you happen to be using - for example, a Strat is far more convincing with the Foxy Lady and Smoke On The Water tones - but the sounds on the whole are as good as we remember. We decided to dive right in and go through a choice of the song presets. "Our Valve Reactor design takes the 12AX7, configures it as a small low-powered push/pull tube stage and uses a transparent solid-state power stage to amplify things to a usable level."Ī power level control on the front panel allows you to alter the amp's output without interfering with the volume balances of your own presets, and there's also now a noise reduction system and an onboard tuner. Clarke: "It's a popular misconception that the valve is used in the preamp it's actually used in the power section," he explains.
We've explained it many times over the years, so let's have an official recap. You can save up to eight completed tones within two channels of four presets and the process of choosing, editing and ultimately saving tones is very straightforward once you've got your head around the amp's basic infrastructure.Ī major USP of the VT and VT+ ranges is the provision of a 12AX7 valve. "It's a painstaking process, that takes weeks of listening, A/B-ing and tweaking until the models are perfect." "We designed our own unique system in which our DSP experts capture the essence and soul of an amplifier, take a digital snapshot of it and then store it away," he says. We ask Vox product development manager Dave Clarke to give us an overview of how the modelling process actually works.
You know exactly what you're getting with US High Gain and Vox AC30, for example.
