NEW RELEASE: Mercuriall Spark Amp Package


The team at Mercuriall have just released the Spark, a VST/AU/AAX plugin that models four Marshall tube amplifiers, four cabs, four overdrive pedals and a set of the most common spatial effects.

It looks pretty kick-ass.

Amps include emulations of:

  • Marshall AFD (four channels)
  • Marshall JCM 800 (two channels)
  • Marshall JMP Super Lead (two channels) with Master Mod
  • Marshall JMP Super Bass (two channels) with Master Mod 
  • Tubes: 12AX7 RCA, 12AX7 RSD; 6L6GC, EL34

Cabinets include emulations of:

  • Bogner Uberkab 412 – 4×12 Celestion G12T-75
  • Bogner Uberkab 412 – 4×12 Celestion V30s
  • Marshall 1960B – 4×12 Greenback
  • Marshall 1960B – 4×12 JBL K120 (vintage)
  • Microphones: Shure SM57, Sennheiser MD441, Royer R121

Pedals and effects include:

  • Noise Gate
  • Overdrive based on Ibanez TS-808
  • Overdrive based on Ibanez TS-808 Lower Drive Mod
  • Overdrive based on Ibanez TS-7 Hot
  • Overdrive based MESA/BOOGIE Grid Slammer
  • Stereo Chorus
  • Stereo Delay
  • Stereo Reverb

“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.”


  • 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

Available as VST/AU/AAX.

The list price is usually $120, but they’re offering an introductory offer of just $99 for a limited time. (Free limited demo available).
