Key Features
The Synergy Fortin Killer Kali captures the extreme precision, aggression and clarity of Mike Fortin’s acclaimed Cali and KK++ amp designs in a fully featured two-channel module. Built for Synergy’s modular all-tube ecosystem, it offers independent tone stacks per channel along with Fortin’s trademark approach to tight, high-gain performance. Each channel uses cascaded Gain 1 and Gain 2 controls for detailed shaping, with dedicated three-way Bright switches that respond dynamically to how hard the gain stages are driven. Whether you want snarling crunch, articulate metal rhythm tones or razor-sharp lead sustain, the Killer Kali delivers with authority.
Additional shaping tools include Fortin’s Violence switch, which activates an extra tube gain stage for increased intensity, and the Sat switch, which introduces a clipping circuit for extra compression and saturation. A three-way EQ Shape switch shifts the tone stack between classic M-style bite, scooped F-style response, or a hybrid voicing for mid-forward impact. Powered by two 12AX7 valves and designed for seamless installation in any Synergy dock, the Killer Kali is a premium solution for players seeking modern boutique high-gain tones with exceptional control and flexibility.
Product Ref: 355015
The Killer Kali represents Mike Fortin’s decades-long reputation for crafting some of the tightest, most articulate high-gain amps in the modern scene. Drawing inspiration from the Cali model and the revered KK++ modifications, this module brings an unmistakably Fortin voice into the Synergy ecosystem. Its aggressive midrange, ultra-fast tracking and cutting harmonic presence make it ideal for advanced metal rhythm playing and expressive, saturated lead work.
Each channel features its own Gain 1 and Gain 2 controls, allowing players to fine-tune exactly how much of each cascaded stage contributes to the final tone. Separate bright switches for each gain control further refine attack and high-end presence. This level of control encourages experimentation and rewards players who want a highly sculpted response, whether dialling in tight crunch tones or fluid, singing sustain.
The Violence switch activates an additional tube stage, increasing aggression and harmonic complexity, while the Sat switch adds a clipping circuit that enhances compression and saturated feel. The three-position EQ Shape switch offers dramatic shifts in tonal structure, giving you access to M-style punch, F-style scoop, or a hybrid option that emphasises upper mids. These tools make the Killer Kali adaptable across multiple heavy genres while keeping the signature Fortin character intact.
Powered by two 12AX7 valves, the Killer Kali delivers the harmonic richness, immediacy and response of a premium boutique amp preamp. As part of the Synergy platform, it installs easily in any Synergy dock and works seamlessly alongside other modules. This makes it a powerful addition to modern guitar rigs that need authentic valve tone, flexible routing, and compact hardware; ideal for studio, stage and direct-recording setups.
