To rate this amp at less than 5 stars would be obtuse to say the least. The value or worth of this amp has nothing to do with it`s price. This amp has been recorded on more songs than a human can count. It has been on more stages all over the world than you could imagine. The Vox AC30 and AC15 are two of the best guitar amplifiers ever produced.
To begin, the tone of this amp, which is the most important attribute, is rich and full but also versatile. You can get deep lows and fat sounds, full and rich, for those who seek such, or pitchy tones suited for the country picker, or anything in between. It can give you huge headroom or you can dial in some fat overdriven tones. With the "Tone Cut" pot you can really dial in to whatever tones you want. The 4 different inputs allow for 4 individual levels as well. And the fact that you can jump channels makes for a hot rodded sound that can give you saturation or overdriven tones to suit those high gain situations.
The Reverb is top of the line, no digital garbage but rich and lush reverb. The Tremolo is second to none as well and in my opinion as good as even those vintage Fender amps.
The speakers are Greenbacks which are also the speakers which have been used in more recordings than you could count. These speakers are capable of pure cleans or the dirtiest of distortions which is why you find them in all sorts of amplifier cabinets including Marshalls.
The level of volume can be low enough for the bedroom, thanks to a master volume, or loud enough for a 300 seat venue without even using a mic.
I`m not biased when it comes to musical equipment but a spade is a spade. I have owned two of these amps and a Hand wired version, as well as Fender Twins, Deluxes, Supers, Mesa Boogie`s Mark 2 B, Heartbreakers, etc.etc.etc. The Vox AC30 is an awesome amplifier that is well suited to perform a wide variety of music genres. There is really nothing negative to state about this amp.
In our day and age we have more choices than we really need and of course there are enough variations of amplifiers out there to suit anyones personal preference. But while many amps are one or two trick ponies, the Vox AC30 is a master of many tricks so to speak.
