SYMBIOSIS: SoCal Killer
55 Helix Stadium Proxy Captures

Experience the unmistakable SoCal-inspired aggression that has made the Synergy Fortin Killer Kali one of the most sought-after boutique preamp modules available. This collection faithfully brings that signature boutique character to Line 6 Helix Stadium, delivering everything from sparkling cleans and edge-of-breakup crunch to crushing modern rhythm tones and soaring high-gain leads.

Rather than simply offering one version of the amp, SYMBIOSIS: SoCal Killer captures the module across three distinct gain stages—Low Gain, Mid Gain, and High Gain—giving you the full range of the Killer Kali's character. Each gain stage also includes multiple boosted variations, allowing you to explore everything from organic amp tones to the tight, focused response demanded by today's modern metal players.

To maximize flexibility, the pack includes an extensive selection of overdrive and boost pedals placed in front of the amp. Tighten your low end with the legendary Maxon 808, Precision Drive, or Savage Drive, add vintage grit with Fluff Drive, or keep the amp's natural character intact with the Grid Slammer. You'll also find the articulate Insight boost, multiple Fortin Fourteen voicings (HD, F9, and F808), Hex Drive, Dirty Tree, and a classic Tube Screamer-style boost, giving you an enormous range of tonal options without ever leaving the preset list.

Every preset includes detailed notes covering EQ, presence, power amp structure, and tonal characteristics, making it easy to choose the perfect sound before you even play a note.

Whether you're after dynamic cleans, punchy rock rhythms, aggressive modern metal, or soaring lead tones, SYMBIOSIS: SoCal Killer delivers authentic Fortin-inspired performance that's equally at home in the studio and on stage.
