Dreadbox Lil Erebus – DIY Build

Dreadbox Lil Erebus - DIY Build

Rewind 4 years to Superbooth 2018 as the production of the Dreadbox Erebus analog synth ended and the world was eager for its replacement. Superbooth was the perfect time for Dreadbox to introduce their latest DIY module the Lil Erebus. Being that this was a replacement for the beloved Erebus, these kits went fast and instantly became hard to find. 

We scoured the internet for months trying to locate a kit in the summer of 2020 and they were so few and far between. Luckily, we clicked on the right link one day and found one of the kits at Robotspeak in San Francisco, CA. After a few quick clicks to pay for the module, we were excited to get our hands on it about a week later.

What is the Lil Erebus?

The Lil Erebus consists of two oscillators, a 2-pole low-pass filter, an envelope generator (ADS), an LFO and the excellent voltage controlled echo effect. It also features 16 patch points that allows you to use it with your modular gear.

At 42 hp, this paraphonic synthesizer was quick to become a heavy hitter in our rack due to its unique capabilities and heavy oscillators.

Erica Synths have been around for awhile and while most of their previous offerings in the modular world were fully built modules, they do have some DIY kits. The Erica Synths Polivoks VCO or Voltage Controlled Oscillator is one of those modules. 

The core of this VCO is borrowed from the famous Russian synth Polivoks VCO, and original matched transistor IC is the same of that was used in Polivoks. These two things give this VCO a very well rounded and beefy sound. (We liked it so much we have 2 of these). 

The gang over at Synthrotek have made these kits available in all their entirety. They have several options available to purchase (links below), including a fully assembled module if you do not feel like building anything. We opted for the full DIY Kit as usual and began warming up or irons!

The Zeroscope is a small 6hp two-channel Eurorack oscilloscope module made by vpme.de. We have had this kit for some time now and decided it was finally time to jump in and put this little thing together. The kit was purchased at Synthcube and it contained all of the necessary parts to assemble the module.

Since this was an SMD build for the most part, we did not record a time lapse video of it, but decided to share pics of the build instead. We also recommend that you polish up on your SMD technique if you are not familiar these types of modules. Parts are very small and require a very steady hand to finesse things correctly.

Synthrotek Crossfader (CF) and 2hp Buff Mult – DIY Builds

Synthrotek Crossfader (CF) and 2hp Buff Mult - DIY Builds

In December 2021, we highlighted a few smaller modules produced by Synthrotek. These modules included the Power Pak, Adapt 1/4 and a Stereo Buffered Mult. The new Crossfader Module (CF) and the new Buffered Mult from Synthrotek are two new modules that join their line of utility modules and we had the opportunity to put them on the build table. 

Just like the previous utility modules, the Crossfader module is a quick and easy build. There are very few hole-through components to complete the module. The Buffered Mult on the other hand, has SMD components and requires finesse when assembling. A novice builder would want to steer away from the SMD soldering until they have had some practice. 

One thing remains true about both of these modules though. Being that both of these modules have a very small footprint in your rack, it is a no-brainer on why they both are“must haves”. Let’s get on with the builds.
