Key Features

  • SS-11X modeling is officially certified and approved by AMT Electronics
  • SS-11X is modeled using our next-gen Neural Hybrid Engine. This in-house technology has been in development for 5 years
  • All tubes are modeled independently
  • Pedals and preamp are working within the same oversampling cycle. Thus, there is no latency build-up and no additional losses when using several anti-aliasing filters
  • Stereo-mode: right and left channels are modeled independently. This mode is useful for processing stereo signals. For example, a panned double tracked guitar
  • Plugin supports CPU multi-threading

* Some of our customers reported that SS-11X under-performs in Studio One and Ableton Live. Observations show that these DAWs do not offer optimal multi-threading experience, which is required to run our next-gen modeling engine. If you run Studio One or Ableton Live and still wish to purchase SS-11X, we highly recommend extensive testing of the Demo version.
