The convenient and powerful Valvetronix VT40+ combo amp delivers the guitar sounds sought after by discerning guitarists of every style. With a 12AX7 preamp tube, powerful new amp models, and the unique Power Level control, the VT40 Plus is ready to deliver the response and sound every player needs.

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 the Valvetronix VT40+ 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 the VOX Valvetronix VT40+ modeling amp 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 VT40+ makes no compromises 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 for the VT40+, 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 VT40+. 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 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.

I was interested in finding a reasonably price amp that had great tone and versatility. I thoroughly researched my options and narrowed it down to a few choices. I went into Guitar Center and tried out several amps within the price range. I had been considering a full on tube amp but was not willing to commit to a single type of sound without purchasing several pedals. Out of everyone I tried the VT40+ by far has the best tone. It is very responsive and works great with aftermarket pick ups. It has seemingly endless different adjustments and features that take some time to figure out fully. The Vox VT+ series were the only modeling amps that gave a true valve feel and tone. There are one or two settings that sound a little digital. Overall the amp offers a great range of sounds from clean, blues, and even metal. I would have liked to have seen a line out feature but definitely not a deal breaker. The Vt40+ sounds great with the amperage turned down but really cooks above 30 watts. I would recommend any of the VT+ series amps for people looking for great tone, wide variety of sounds at a reasonable price.

This amp has a problem with producing unwanted noise in the form of a hiss (also called the snare effect). See the Vox.com website forum for more info on VT40+ Hiss. It limits your use of the gain and effects and you certainly wouldn't be happy with recording the sound produced. Very unfortunate because this could have been a great amp.

Awesome amp!!

By Robert

from Chicago, Illinois

This is the first guitar amp I ever bought, and after trying a Marshall DSL40C and Blackstar HT Metal 5, the Vox is my favorite and perfect for practice. I'm amazed that this little amp can sound so good! In my opinion it's hard to beat for the price and versatility that it offers. It has exceeded my expectations, I thought I'd have to spend around a thousand dollars to get a great sounding combo amp, but I was wrong! It took me a little while to figure out all the different settings, but it's intuitive and very easy to operate. Set on "Basic", "US 2x12" with the treble and bass turned almost all the way up, mids at half way, and the metal distortion level at the 2 o'clock position played through a single coil Strat this amp sounds amazing. If you play a lot of metal and want deep, full, fat sounding distortion I would highly recommend this amp. It sounds great on the clean setting, too, very clear and crisp. I actually had trouble telling the difference between the all tube Marshall, Blackstar, and this amp. It's not exactly the same as an all tube amp, but it is very, very close, the warmth is definitely there. The built in effects are great too, beats spending a ton of money on pedals. I've had this amp for 2 years and it has never had any problems.

excellent amplifier for recording and gigging


from Sarasota, Florida

Not normally a fan of modeling amplifiers. This thing breaks the mold. I have two Vox AC-30 top boost amplifiers an old Fender Twin Reverb and an arsenal of pedals. This amplifier changes everything. Built in tuner and the ability to place effects in chain and save them as presets. All very nice, but none of this means a thing as it is about the sound. OMG this thing sounds amazing. It nails the Fender sound, Matchless, Orange, Marshall, and of course the vox sounds are simply the best I have heard. Plenty loud enough to play most jobs around town with a 4 piece band. Do yourself and back a favor at 23 pounds much easier to haul then a 70 pound AC-30. Just take a listen and compare to any other tube or solid state amplifier then decide for yourself

It's a vox, you can't go wrong

By ryan

from Albany Oregon

I typically prefer tube amps and over the years I've been fairly uptight about this preference but I've been very impressed with this little amp. All the sounds and features you get for $250.00 is very impressive. The VT40 is a ton of fun to sit down and play with. As far as recording goes you've got a ton of different sounds to play with,you can record any type of style with one amp, and the volume this little guy has is very impressive. For the price you can't miss.

Astonishing. no kidding.

By Mark Aldridge

from Raleigh, NC

I've purchased 3 of these. Really a great sound, using Fenderr or Gibby style, whatever, all guitars sound great. You can throw away about 95% of the rest of amps currently made and just leave these amps, that's OK with me. Head and shoulders above most any other guitar amp, and believe me, like many others that have played for decades, I have owned & operated a Lot of amps. I don't care where they are made - Vox comes back soaring like an eagle with this amp. Valve Reactor is fine engineering. I'll tell, these sound as good as the ones from the 60's when the Beatles and all the Mercy bands used them (they were very expensive) Heck, these even sound Better! And no, I am not kidding. You might get a lemon at this price point. Heck its so cheap, throw it out and order another... This is a Triumph. I am making a note here: Hugh Success. Thanks, VOX ! You should hear the Voyage-Air Telair through this thing, and an Epi Casino. wow! :)

Really Nice Amp

By Mark Aldridge

from Raleigh North Carolina U.S.A.

Best sounding amp I think I have ever played. I now have two, and may buy some more, or maybe the VR series. I have played plenty of 100 watt Marshalls, Fenders, Peaveys, Rolands, Yamaha, etc etc. Vox just sounds better. I do not know how they do it but I have read that its not the tube, but that that do not use negative feedback in the amp section. Whatever. However they do it it works. One complaint: would like an output phono jack from pre-amp and likewise input to main so I can chain several together - minor. Don't know if its a Celestion speaker or other - no name on it, but sounds great and VERY VOX. Second one I bought was a "deal" from some company and it had a hum. At this price, I chucked it and got another from GuitarCenter. Amp is a lot louder than you might expect, just put the setting on AC30 and leave it there, put on a little echo and compression, and "You Are There". For me, this is The sound.

Perfect for my Epi Dot Studio

By brian gendreau

from Westerly, RI

Got a used Worn Vintage Sunburst Epi Dot Studio about a month ago and brought it home to my Marshall MG10CF (amp). I had that amp for a little while now and it served my purposes, until I got the Dot. That guitar was too much and I knew it was time for tubes. Went into GC with a coupon in my hand and the intention of buying a brand new VT20+ but saw this guy standing on top of the pile of used amps. Grabbed a Dot Studio from the wall, plugged in, set to clean and went to town. This is a match made in tonal heaven. Outstanding sound, everything functioned, what more could you ask for? I was initially hesitatnt to purchase this amp because of all the bells and whistles. I have played the Line 6 stuff (which is great and fun for sure) but did not want that sound for myself right now. I have been builing my guitar arsenal to be pretty bare-bones basic and this amp is a bit of a contradiction to my style. If you can't sound good clean then why mask it when you should practice more? Anyways, there is a 40 page instruction manual that you need to get familiar with to take full advantage of this great amp. I had to take a star away for the instruction manual and not including a foot pedal with the new amps. Just personal gripes though.

Parallel in Tone plus effects

By Diego Rose

from Buffalo, NY

I've had this amp for almost two years. In the interim owned a Fender Deluxe Reverb 65' Reissue (for eight-nine months-it got too loud for neighbors). Now when comparing world famous nectarean tone of the Fender Deluxe '65 I got to be careful. I got to be careful. I'm taking time to write this review to facilitate the process of all concerned here (merchant and non-merchant which entails hobbyists,aspiring musicians, as well as our beloved shopkeepers who I also like to call experts and G.C. staff). The tone coming out of this 10" speaker is rich real!! As an example on several occasions I've sat and wondered if my tracks "rock instrumentals" were recorded from Fender Deluxe '65 (guitar God Paul Gilbert was generous as he always is to have heard a 2&1/2 minute composition at Mr. Big last summer in Buffalo) or from this equisitely beautiful, traditional and iconic little piece of equipment. And the best part of the Vox Valvetronix Vt40 Plus is a price that will have your wallet happy! Hands down!

Very Good Entry Amp

By Joe Evers

from Boston, MA

So I have had this amp for about 6 months, and played about a dozen shows with it. Anywhere from 30 to 120 people, and it didn't need to be mic'd once. The clean has a warm tube sound to it, and its the best channel to use any of the 22 built in effects. Although, i have never found any of the effects worth using, they may be useful to some. After clean is the cali clean, which is just pretty much clean with more treble and more breakup. I have never been able to find usable sound from US Blues, 2x12, Vox AC15 or AC30.. but then comes the UK Rock, which gets great classic rock tones. Followed then by UK Metal, which is very responsive to your picking, and is great for solos, and does very good with punk-ish metal, such as August Burns Red. US High Gain is my favorite, and does punk just perfectly, like Nirvana and Green Day. After are 2 more high gain channels, US Metal and BTQ Metal, which aren't great in my opinion, and have a lot of buzz. The attenuator is a great addition, making bedroom practicing easy, or crank it and easily play a show. The reverb is very natural sounding, and using just a touch sounds great. Overall, it's a great entry level gigging amp, and will help you find your sound.

Great tool for the gigging pro

By Ed Kliman

from Austin, Texas y'all

I needed a small, inexpensive modeling combo that would work for pit orchestra, recording sessions, clubs and whatever else. I play for a living and in a huge variety of settings and musical styles. I A/B'ed this unit next to the Peavey Vypyr 30 and a Line 6 amp of comparable size. Making a decision just on fundamental quality of guitar tone, this amp was head and shoulders above the others. There may be better automation or other features on the other amps, but the tone of this amp is what sold me. I got it out on a reasonably loud rock/funk gig last night (my first gig with this amp) and was pleasantly surprised at how well it did. It won't compare sonically with a Matchless or other high end tube amp, but at this price i'm not expecting it to. This amp is light AND loud. The variable power setting went a long way on selling me on this amp, this being a particularly useful feature for recording and pit orchestra/theatre gigs. Overall, this amp is a real pleasure to use. I'm writing this review for other working pros like me who are looking for a good, cheap workingman's amp that will cover almost any situation you find yourself in. Highly recommended.

Mind blowing

By Jeff Cliburn

from OKC, OK

OK, it's a beautiful world when you can get these tones for $250. In particular, the Blackface and ac15 are killer. Marshal type stuff is respectable. All in all this thing is a freak. You just don't hear smaller amps that have a really firm bottom like this. Effects are excellent considering they are built in. Sounds great with SC or HB pickups and behaves correctly when interacting with the amp/guitar choices (sc/jangly blackface, etc). There are only 2 caveats that I can see: 1 (and this is huge) there is no line out except for the headphone jack (which defeats the speaker)- terrible oversight. 2) you have to take the entire back off the amp to change the tube. It sounds great out of the box, but I would recommend swapping out the 12ax7 for a NOS as the amp architecture is such that the power section behaves like a tube amp using both sides of the dual triode as pre/gain. I'd go on a limb here and say that you could teach people using this amp as to what a tweed, blackface, AC 15, Ac 30 top boost is supposed to sound like. I'm not saying this renders your vintage AC 30 tube amp worthless, but I'd have the 80 watt model backstage when the afformentioned goes out while your on the road. In summation, I build tube amps and modify electric guitars. This purchase was for the purpose of have something really pristine to test guitars off of. However, it gets used a lot at gigs by several band members because of the incredibly excellent tones. If you buy the matching foot pedal, there is no reason why you couldn't do serious gigs with this amp- just have to stick a 57 on the grill..
