Production Note

Production of Ceres™ pedals will begin the first week of February. $375 is the introductory price during NAMM, and will revert to $400 on 2/1/19. ETA to begin shipping is on or before 3/1/19.

Shipping Note

We have now added USPS as an option as well as Flat-Rate FedEx 2-day for USA folks, which will likely be the most cost effective options. For those who ordered with more expensive options selected before, we will determine the best method and refund the difference on your order balance when it comes time to ship.

If a good shipping option and reasonable price is not calculating, please select the Defer Shipping method and we will manually calculate the best shipping cost at the time of shipping. Also, feel free to contact us for a quote.



The Ceres™ preamp, the newest addition to the KSR line, contains our signature tones from three of our amplifiers – the Ares, the Artemis/Gemini, and the Colossus.

Ultimately, the Ceres™ preamp distills our KSR sound into a small package. At only 5.7″ x 4.7″, it features many of the same functions present on all our amps — such as the Mode, Feel, and Bright switches. Moreover, this pedal provides the ultimate mobile tone versatility from weekend gigs to fly rigs. It also delivers the KSR signature sound to any board or interface for live and studio purposes.

Top mounted jacks allow for easy integration into your existing pedal board. Unique to our pedal operation, we include 3 bypass modes — True Bypass, Buffered Bypass, and Clean Bypass. In True and Buffered bypass the pedal operates as expected, no tonal coloration. The Clean Bypass mode enables the top row of Tone and Volume knobs accessing the Clean channel. These various Bypass Modes allow for integration into any style of rig — from driving a power amp directly (Clean mode), hitting a clean amp down the chain on your pedal board (True Bypass mode), or at the start of your pedal board, driving your other pedals into a clean amp (Buffered mode).

The preferred operating method is to run the Ceres™ into the input of the effects loop return of any amplifier head or directly into a power amp, but it will also work just as well when run into a clean channel with some EQ tweaking.

Time based effects (delay, chorus, flange, etc) should be placed after the Ceres, before the power amp. A simple loop switcher can even be used to create effects loop(s) between the Ceres and power amp.


The Ceres includes two integrated footswitch buttons to activate the 3 channels. The left button toggles between Bypass and Rhythm/Lead. The right button toggles between Rhythm and Lead. With the Bypass Mode switch set to Clean, bypassing the pedal actually activates the Clean channel.

The gain controls in all channels feature the same range from clean to saturated signals and operate as close as possible to the full size KSR amps. They function without any unwanted top-end artifacts typically associated with solid-state circuits. The Ceres™ EQ options then make for a highly versatile Pre-Amp pedal giving you as much control.

Here is a quick overview of the switch functionality of the pedal, mirroring our signature amplifiers:

Up = On, Down = Off. The switch works just like a typical Gain pot bright capacitor in that the lower the Gain setting, the more the effect.

Up = Fat, Center = Tight, Down = Thick

Up = Ares Crunch, Center = Artemis/Gemini Red Mode, Down = Colossus Lead


Looking at the front of the pedal, top-right is the 9V DC input, then Guitar Input, Output to amp, and finally top-left is the Control port.

The 9V DC input requires at least 175 mA to function. This is equivalent to the high-current output of a Voodoo Labs Pedal Power, or similar. Please do not exceed 9V as the pedal will shutdown to protect the internal electronics. We generate 18V internally, so providing more than 9V is simply not necessary, or possible.

The Control port is a 3.5mm (1/8″ headphone) TRS jack that allows control of the pedal channels and future expansion. Simply use an 1/8″ to 1/4″ TRS cable / adapter to connect this to momentary contact closure relays, and you can completely control the pedal, just as you can with the two foot switches.


We are proudly manufacturing this pedal completely in our Cincinnati facility. CNC machining, powder coating, laser etching, circuit board assembly are all performed under our roof — no outsourcing.
