THD Electronics Hot Plate Attenuator

It’s not a secret that nothing beats the sound of a great guitar tube amp cranked up. When a tube amp is driven to overdrive, rich and musical even-ordered harmonics flow in abundance and the amplifier seems to take on a new sense of dynamic character that responds better to a player’s touch. It is this feel that gives a tube amp an organic and natural sense, while solid-state amplifiers are considered more sterile in sound because of the lack of this response or harmonics.

The age-old problem has been getting the great tube amp sound at lower and more realistic levels. As the majority of musicians play relatively small clubs and in even smaller practice rooms, only the minority (i.e. those famous guitarists!) get the real opportunity to play these tube amps at the volumes that they sound best. As a result, many of our classic and much beloved Marshall, Fender, and Vox amplifiers are often seen used with distortion and fuzz boxes to compensate. While my personal belief is that these distortion and fuzz boxes are useful in some applications, they are certainly not the best way to achieve great tone when used strictly as the sole source of distortion.

Vox Valvetronix AD120VTX Amplifier & Vox Tonelab

The Vox name should be familiar to virtually any guitarist that’s taken that quest for tone or is a regular visitor to this site. That name is of course associated with some of the most famous amplifiers of all time, including the AC15 and AC30. The AC15 had its beginnings in the late 1950’s with the AC30 following soon afterward – and now, even after more than 50 years with the same circuit design at their heart, these are still two amps that continue to be revered for their tone and are as musically useful today as they’ve ever been.

So when Vox announced two years ago that it was moving toward the production of modeling amplifiers, no doubt there was skepticism about what the final product would be like. I’m sure mutterings of “Why mess with a good thing?” were heard and told as well as how a company rooted in “older technology” would do with the creation of amplifiers based on new technology and engineering requirements.
