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 applications.

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 external control input, then Guitar Input, 9V DC input, and finally Output to amp.

The 9V DC input requires at most 200 mA to function. This is accessible via 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 optimal voltages 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.

    The Ceres is my new go to for just about everything. This pedal absolutely slays!!! \m/\m/

    I’m blown away with preamp. Whether it’s in a live or recording environment it shines bright and strong. It’s seems that every time I purchase one of amps or gadgets it inspires me to become a better player. 5/5, great job once again, Kyle!

    Could this pedal be any better? I don’t think so.

    I break the KSR Mold as I’m not a high gain guy but its nice having it on tap.

    Rhythm channel, Ares crunch mode, bright switch down, feel middle is unreal with single coils. I just adjust the gain to taste and I’m in business. I can go really bluesy but its never flubby or muddy.

    I’m building an entire small board around the Ceres for direct to FOH settings (I do a lot of theater work). Stick the Ceres in front of your favorite IR box and run direct to the sound guy. Its perfect.

    The clean channel, however, is the unsung hero. Spanky, tight, with a sweetness to it.. very smooth.

    I haven’t used the lead channel much… I’m not really a lead player. But the tones I coaxed out of it would certainly be useful for people that are looking for that.

    I am still dialing this in for use without an amp at all, which I believe it will excel at. The issue I have, is that it sounds so dauntingly massive through the return on my Colossus that I don’t really want to power the amp off to go amp-free. I know I have to get around to it. It sounds huge with the Brit Green 3 IR on Wall of Sound in Cubase. There’s more of everything you need, on tap.

    If there’s a weakness, I would say it’s that this pedal wants to be either clean (which sounds really good, strangely) or heavy. I haven’t stacked any OD or fuzz in front of it, but I prefer my real amps for the mid-gain thing.

    But then there’s the heavy thing. I don’t even need my amp or other pedals to make brutality. The pedal does it in spades in a very useful, relatively wide tonal band. I’m playing a Korina guitar with Arcane pickups, and I am not noticing a huge difference on the feel switches, but every other control makes a very, very noticeable difference.

    I think we’re going to hear this pedal as the primary tone on a bunch of metal albums in the near future. It’s BIG sounding. It plays well with standard tuning and super low tuning. Mine is orange. It’s a keeper.

    After my buddy Justin RAVED about his KSR Gemini, I started researching the company and learned that a preamp pedal was in the works. After seeing a few videos from NAMM 2019, I knew I had to have one. Fast forward a few months and I finally get my KSR Ceres in the mail and instantly fall in love. I’ve uploaded a few videos on YouTube raving about my Ceres and feel that everyone should own one. It is the ONLY preamp pedal you’ll ever need and I have a bunch of different preamp pedals in my arsenal, but this KSR monster is without question my all time favorite!! Get it! Trust that you’ll make hundreds of thousands of dollars over the rest of your life!! This KSR Ceres is worth every penny, get it now! You’re going to LOVE it!!! Thanks Kyle!!
