The latest classic amp to be modelled in software for running on a computer is the Vox AC30. It has been made available by TC Electronic of Denmark as an optional plug-in for their PowerCore DSP card which is itself available as a PCI card or external FireWire unit. PowerCore is the open platform DSP engine for professional signal processing for Mac and PC that seamlessly integrates with any Audio Units- or VST-compatible host application. PowerCore includes world-class quality TC plug-ins right out of the box. Optional plug-ins like the TC Thirty are available from TC and a growing number of respected 3rd-party developers.
The amp modelled is of 1961 vintage and the emulation has a variety of easily configured features including four different drive models that can be used to expand the sound and create different tones. Just like the familiar AC30 overdrive modification, TC Thirty has a treble booster option that emulates the singing, crunchy sound of Queen's Brian May. Running completely on PowerCore, TC Thirty provides the sound and behavior of the normal channel found on that amp. The resonance can be switched to different frequencies so that a wide range of guitars will be able to get close to that classic tone - and create their own unique sound as well. Guitarists will appreciate PowerCore's 'No Latency' mode, which enables TC Thirty to be played in a live recording or performance situation. TC Thirty also offers an oversampling option for even higher processing quality than in standard mode. Up to four standard mode instances of TC Thirty can be run on one PowerCore Firewire DSP.
