Cereal Instruments SWERVE and RAZE – DIY Builds

Cereal Instruments SWERVE and RAZE - DIY Builds


We decided to do a few things a little different this month by not only having more than 1 build/review, but having 4 by one company… Cereal Instruments. Their utility modules are something that every rack should have in them. We use them all of the time not only for performance but for recording or just jamming. Check out the latest builds of the Cereal Instruments SWERVE and RAZE.


The Cereal Instruments swerve is a passive dual performer switch with mute buttons built in. You can toggle between sides with the toggle switches or temporarily mute one side or the other.

Jacks are either in’s or outs and are labeled simply as “a” or “b”. One thing to note is that this 2021 edition of swerve is not the same as Cereal Instruments earlier release of ‘swerve’ (which can be found here). This swerve is a performing switch whereas the other ‘swerve’ was a rotary switch that you could route cv, or effects to other modules.

Cereal Instruments is back with another module and this one is known simply as ‘swerve’. The ‘swerve’ is considered a novice build with its layout consisting of 1 potentiometer and 8 jacks. Each of the top jacks can be switched by the any one of the three below it. A simple turn of the rotary switch and the signal quickly changes. 

But what is this module used for? This module can be used to route cv to different inputs to control the output of the signal. It can be used for vibrato, cutoffs, a signal & hold and many other applications including a straight input to 3x output.  Cereal Instruments ‘swerve’ is also self patchable so that you can reroute signals almost as a bus within your rack. One thing is for sure is that this little 4HP module is very versatile and for a passive module, its circuitry is simple and yet complex. Let us get on with the build shall we?

Let’s get on with the build shall we?

For this build we utilized top down soldering for the beginning and bottom side soldering for the latter. Start by setting everything out and separating all of the components so that they are easily accessible and easy to find. The jacks are up first.

Place the jacks in line on the PCB making sure to line them up correctly with the circuit. We have included a PDF of the document that comes with the kit in case you need a quick reference. It can be found in the links below.
