In search of little monsters that deliver the ultimate warmth of tubes, we came across the AC4TV, which was introduced at NAMM 2009 (if memory serves). It's a cute, warm-sounding little 4W amp inspired by the 1960 VOX AC4, and it comes with a 10" Celestion speaker. Let's see what it can do.
Finish
As expected, VOX doesn't disappoint; it stays true to its meticulous styling, in keeping with the look that places it among the world's top brands in guitar amplification. In this case, we have a small combo amp with a custom/vintage flavor, finished in creams and browns. Personally, I find it elegant and attractive, although, you know, to each his own...
The Search for Warmth
As we've mentioned in previous tests, the number of guitarists who rebel against modeling is not negligible. For them, you have to look for alternatives that deliver real, gritty, authentic sounds. Tubes deliver a kind of saturation that's hard to find in solid-state amps or modelers (though it depends on the case). The AC4TV comes loaded for bear: two 12AX7 tubes in the preamp and one EL84 in the power section. No modeling here, this is the real deal.
Size and Focus
This is an especially small and manageable combo, which makes it easy and light to carry. We think this product was basically designed for working at home or in places where too much volume could be a problem. Despite its tiny 4W, the little guy kicks out a generous punch. So much so that VOX has included a power selector that runs through:
a) 4W output
b) 1W output
c) ¼W output
These settings let us drive the preamp hard, even at a really moderate volume. So what do we have here? I think it's a very tempting treat for working at home or in the studio, without disturbing anyone too much and with the sonic reality that tubes deliver.
The Sound
Given its simplicity, there's not much point in picking apart its front and rear panels. In short: input, tone, volume, power switch, on/off LED and power selector, plus a speaker output on the back for a 4W, 16-ohm cabinet.
I think the sound, considering what it costs and its size, is very well done. We ran different guitars through it, from classic bright single coils to thick humbuckers. Its sonic range is moderately versatile in terms of everything from clean to overdriven: we go from clean with bite to a feisty crunch.
Pros
If you take the time to dial it in and add the right pedals, you'll have a compact, quite versatile, lightweight tube rig at your disposal. For practicing and even recording good-quality demos, you'll be well equipped.
Limitations
The 10" speaker and the very closed (and small) cabinet add a somewhat nasal tone that is ideal for certain premeditated colors (especially British-style overdrive à la Brian May, with prominent mids). However, you'll have to work its tonal possibilities a bit to get thicker, more open and heavier sounds.
Remember that it's a 4W amp, so if you plan to take it to the rehearsal room with a drummer, a full kit, heavy ideas and playing all out, you're in for a rough time.
Conclusion
We think this is a tempting indulgence. If you work at home but want authentic sounds, experiencing tube saturation, this VOX is a perfect fit. It certainly can't be compared with other amps featured in the same special, but remember: it costs 270€ versus the 2,400€(?) that some others ask. It makes no sense to treat this as a head-to-head comparison. These are simply different alternatives for those looking for resources other than modeling. Now it's a matter of analyzing where you're going to use it, how much power you need, how far you have to watch whether you're bothering anyone, how demanding you'll be of your new amp, and, of course, your budget.
What seems clear is that this VOX offers fantastic value for the money. Considering what it costs, I'd say it's one of the best alternatives, even if it's not the best amplifier of those reviewed here.
