For our latest giveaway we’ve once again teamed up with Mercuriall Audio Software. This time around, you have the chance to win its Ampbox-powered model based on the legendary Marshall JCM800 2204, a 50-watt master volume-equipped amplifier.
From edge-of-breakup bite to classic crunch and snarling riffs, Spark stays fast, dynamic, and mix-cutting with that unmistakable upper-mid growl.
Engage the optional #34 mod for a refined hot-rodded voice inspired by Slash’s modded JCM800 era, or switch to the #36 mod for a thicker, more driven Appetite-style gain structure with extra saturation and singing sustain.
Mercuriall Audio has generously donated two licenses of Spark, which is normally sold for $99.99 USD. All you need to do for a chance to win is leave a comment below. The lucky winners will be picked randomly from all entries submitted before the end of this Wednesday, April 8th, 2026 (11.59pm CET).
Good luck, and check the video below for an overview of Spark in Ampbox, or visit the Mercuriall Audio Software website for more details.
