Sound Pure's Take

Co-designed with high-gain innovator Mike Fortin, the all-tube Synergy Fortin Killer Kali Preamp Module captures the complex, high-octane British-voiced drive of the Fortin Cali amplifier in a compact modular format. Powered by two 12AX7 tubes, it features two completely independent channels, each equipped with dual cascaded Gain controls (Gain 1 and Gain 2) and dedicated 3-way Bright switches for fine-tuned top-end bite. Both channels offer a Violence switch to engage an extra tube gain stage, a SAT switch for added diode-clipping compression, a 3-position EQ Shape switch to shift between Marshall, Fender, and custom midrange curves, and a PCB-mounted Gain Structure switch to tame overall gain when needed.

From Synergy Amps

The Synergy Fortin Killer Kali is an all-tube, two channel module designed with Gain connoisseur Mike Fortin.

With a pedigree of modifying and designing amps (within the realms of Marshall, Vox, Hi-Watt, Randall and Fortin Amplification) that spans well over 30 years, Mike is widely accepted as the harbinger of complex modern high-Gain tones. The Killer Kali module is based on the Fortin Cali amp (complete with the Violence and Sat boosts) that brought the legendary Cali and KK++ mods to a production model; this British voiced monster will allow Synergy users to fully experience this extraordinary piece of modern sonic art.

The Killer Kali is a two channel pre-amp, designed to work exclusively in the Synergy Amp systems. Each channel is completely independent and enjoys its own tone stack and multiple tone shaping features.

 

Gain 1 and Gain 2

Cascaded Gain stages. Gain 1 controls the first gain stage whereas Gain 2 controls the second gain stage.

 

Bright Switches

3-way Bright switch for each Gain control. At the top is the Brightest, most aggressive tone. The Bright switches are directly connected to the Gain control so the higher you have the Gain, the less the Bright tends to affect the tone (similar to the Bright control on a standard Plexi Amp). In the middle it is full range, so is unaffected by the Gain control. At the bottom position, the Brightness is similar to the classic Bright control on an 800 2203.

 

Violence Switch

In the down position, it utilizes the three Gain stages, when up it brings in an additional tube Gain stage.

 

Sat (saturation) Switch

Down, no change. Up, adds another clipping circuit that increases compression and Gain.

 

EQ Shape

 

A three-way switch that changes the points of the EQ. Up is a typical M style tone stack, the middle is more F style (more scooped) and then all the way down is “somewhere in between” - shifting up the treble and midrange.
