Neutral Labs NERMAL – DIY Build

Neutral Labs NERMAL - DIY Build

In the world of modular synthesis, there are many companies that offer distortion modules, but few of them really stand out. The Neutral Labs NERMAL is a destructive 3 layer distortion module that is able to modulate frequencies in the audio range to produce some rather unexpected harmonics. 

Known primarily for the desktop synth ELMYRA, the NERMAL is Neutral Labs first stab at eurorack and from what we can tell, it won’t be their last. We were anxious to get our hands on this build and learn all about its unique abilities. 

The Kit and where to get it (in the U.S.)

After seeing a few demos of the NERMAL, we knew we had to track one down. We ordered up from our friends over at Synthcube and within a few days it arrived safe and sound. Upon cracking the box open we were shocked to see the care in separating the components into “sections” or smaller packaging.

Neutral Labs really made it easy to keep the parts from getting all mixed up. They even state on their build document that one needs to go through one bag of parts at a time so that you won’t lose parts or have to double check resistor values. This was pretty rad that they were thinking of the builder.

The Erica Synths SWAMP is a random CV and audio generator inspired by the famous Wiard Wogglebug module; it’s often the heart of self-generating patches and brings controllable randomness to any modular system.

Synthrotek did the world of DIY builders a solid by putting together these hard to find discontinued kits, and we have been wanting to get our hands on the SWAMP for a long time…and now you can too!

Before hoping straight into the build, let’s take a step back and highlight what separates this module from the original Wobblebug. 

The Erica Synths SWAMP module introduced numerous modifications and improvements to extend the potentiometer range. It added an audio input, which, when connected, replaced the internal Tone oscillator, and the expensive dual vactrol.

The S&H (sample and hold) circuit was build around the Riga S&H IC (AS1100CK2) and ES added audio waveform selection switches, CV output configuration jumpers and much more. All of these are reasons to have just one in your rack!

To sum everything up, the Erica Synths SWAMP is an advanced multi-level kit that can pose a few challenges for even the experienced builder. Packed and distributed by Synthrotek, the entire DIY line of modules is now available for you to take on! (so we had to)
