VOX AC30 Bearfoot Emerald Green Distortion Machine + TC Electronic Spark Booster It’s hard to believe that the Vox AC30 is over 50 years old, or that it was developed at the request of musicians who couldn’t hear their guitar tones over throngs of screaming fans. Though there were many British amp builders back then, none of them were nearly well received as Marshalls or Voxes. In fact, Vox amps may have the advantage in notoriety because some band called The Beatles used them. When the AC30 originally arrived on the scene, the “Top Boost” everyone knows and loves actually wasn’t a standard feature. Eventually, the amp gained its signature argyle grillcloth. Right around this time, Vox began implementing its Brilliance feature into many of its models. Eventually, this came to be known as the Top Boost channel, which was basically an extra gain stage with treble and bass controls. It’s hard to find a better “cranked AC30” tone than that of the Emerald Green Distortion Machine by Bearfoot. There are four knobs: Volume, Voice, Bass and Treble. The Voice control is basically the “Vox knob” as turning it allows players to dial in Voxiness with ease. The TC Electronic Spark Booster is much like the Top Boost or Brilliance of a Vox AC30, as it is one of the only extra gain stages one can add to an amp with individual Treble and Bass controls. Also, there is a Mid setting on the Spark, so players can sort of “reverse” the Vox sound by adding the mids in after the gain, for some interesting sounds. ToneReport.com 21
