The Synergy Fortin Killer Kali tube preamp module brings the revered Fortin Cali amp's modern high-gain power to Synergy's modular amp ecosystem. Created by legendary amp designer Mike Fortin, this module captures the essence of the Cali and KK++ mods, delivering British-inspired tonal aggression with unparalleled precision. Featuring dual independent channels, each with cascaded gain stages, 3-band EQs and advanced tone-shaping controls, this all-tube module redefines versatility for high-gain players. With two 12AX7 tubes ensuring rich harmonic complexity and responsive dynamics, the Killer Kali module is a true testament to Fortin's mastery of gain design. Whether for crushing rhythm tones or soaring leads, this module provides refined control over your sound.

Cascaded Gain Stages for Aggressive Tone

This preamp module features two independent gain controls per channel, each offering cascaded gain stages that deliver the signature Fortin punch and clarity. Gain 1 shapes the initial drive, while Gain 2 adds depth and saturation. Paired with dual 3-way bright switches, players can sculpt their tones with precision, from razor-sharp clarity to warm, rounded distortion. The gain structure switch further refines the overall gain response, ensuring tight low-end and focused midrange articulation. These advanced controls make it easy to achieve crushing tones that remain articulate even at extreme gain levels.

Violence And Saturation Switches for Dynamic Gain Control

The Killer Kali module introduces two innovative switches that expand its gain capabilities. The Violence switch activates an additional tube gain stage, creating explosive overdrive with enhanced harmonic richness. The Saturation (Sat) switch adds a clipping circuit for increased compression and sustain, making it ideal for lead tones that cut through any mix. These features provide dynamic flexibility, allowing players to shift seamlessly between tight rhythm tones and searing leads without losing definition or punch. With these gain-enhancing options, this module delivers exceptional control and tonal diversity for modern players.

Three-Way EQ Shape for Tailored Tonal Response

Each channel of the Killer Kali module includes a three-way EQ Shape switch, enabling players to fine-tune their tonal spectrum. The up position offers a classic "M-style" tone stack for balanced mids and highs, while the middle position delivers a scooped "F-style" response for clean and articulate lows. The down position shifts treble and midrange frequencies upward for cutting, aggressive tones. Combined with the 3-band EQ, this feature allows players to tailor their sound for any playing situation, ensuring clarity and presence in both live and studio environments.

Robust Build With Configurable Cathode Selection

Engineered for durability and tonal accuracy, this module is built with precision PCB-mounted components to withstand heavy use. The patented three-position cathode selection switch lets players adjust the input tube's bass response to match their preferred circuit characteristics, offering greater control over tightness and feel. With easy installation and compatibility across Synergy preamp docks, this module is designed for reliable performance and effortless integration into your rig. The Killer Kali's construction ensures consistent tonal precision and long-term reliability for demanding players.
