My name is Janos, I like playing e-guitar & tweaking my guitar pedalboard as a hobby. I'm working as an audio software programer and studied electrical engineering. Coming from this background, I thought that the (guitar/audio) world would need a good sounding, good looking & free open source guitar distortion plugin.

So... May I introduce to you: The Schrammel OJD. Just add it to your FX chain before your digital amp simulation of choice and get that distortion sound that simply fits the mix perfectly.

Thanks goes out to my employer Sonible for supporting me with this project by supplying their infrastructure to build this plugin. Head over to the Sonible online shop and have a look at their great plugins as well.

The OJD is released under a GPL-3.0 license. I believe that free and open software is a great thing in a free and open world. A propos, if the OJD reminds you of a pedal built by someone who got quite unpopular because of racist posts regarding the #blacklivesmatter movement (in such a way that e.g. even platforms like Reverb banned those products) I want you to know that for me a free and open world does not only need free and open source software but should first of all be free from any form of discrimination and racism. So, maybe this plugin is a nice way of enjoying that sound without looking at the logo that you no longer like looking at...


Schrammel OJD is heavily inspired by the schematics of a modern classic analog pedal, digitally built with my favourite C++ framework JUCE.
I plan to post some nerdy in-depth technical background information on the modeling approach of the OJD as well as some audio programing stuff to my blog from time to time. If you'd like to study the code or even build the plugin from source yourself in the meantime, have a look at the OJD Git repository
