We first brought you preliminary news of this back in September. Now Mercuriall tells us that Spark has been released. Here's the story in their own words...

Mercuriall Spark is a VST/AU/AAX plugin that models four Marshall® tube amplifiers, four guitar cabinets, four overdrive pedals and a set of the most common spatial effects.

Spark is the realization of all our latest achievements in the field of real-time electric circuits modeling. First of all, it's a tube push-pull power amplifier that is working with a reactive load (guitar cabinet), with negative feedback and electric feed chains. This allowed us to implement a truly realistic poweramp saturation (very important for the majority of the Marshall®-based amps), realistic work of the Presence knob and made possible to take into account the influence of the output and power transformers.

We have considerably improved the cabinet section. Apart from the smooth positioning of microphones, we added an option to mix sound of two mics. This allows you to find pretty much any desired sound. There are four cabs and three microphones at your disposal.

Despite the fact that Spark is an amp and cab sim above all, we gave a lot of attention to the FX section. There is a Noise Gate at the input, as well as a number of pedals: there are currently four overdrives, implemented with our proprietary technology of the electric chain modeling. As for the spatial effects - there are Chorus, Delay and Reverb.

Spark's UI continues our approach of simple usability at no expense to a wide functionality. All main actions require just a single click. We pay a lot of attention to the design, that passes a lot of iterations of adjustments and improvements, offering you a very simple and functional solution.

Key Features

  • Electronic circuits of amps and pedals are modeled with our custom technology using Neural Networks
  • Pedals, preamp and power amp are working within the same oversampling cycle. Thus, there is no latency build-up and no additional losses when using several anti-aliasing filters
  • Realistic and smooth positioning of up to two microphones simultaneously
  • Several preamp and power amp tubes to choose from
  • Stereo-mode: right and left channels are modeled independently. This mode is useful for processing stereo signals. For example, a panned double tracked guitar
  • Delay and reverb can be used in parallel to get a more expressive effect without extra routing
  • Plugin supports CPU multi-threading

Introductory price: $99 (normally $120)
