Nexus kit

The Nexus Distortion/Sustainer is Ram?s Head Muff variation.

It features two notable changes that make it stand out. First, the tone control has been replaced with a passive Baxandall tone control (also called a James tone stack) allowing independent adjustment of bass and treble frequencies. With the right settings, you can get a very close approximation of the mid-scoops of several different Muff variants, or you can come up with something entirely your own. Second, a JFET-based gain recovery has been added to help counteract the about 20dB signal loss of the tone stack. This JFET stage is placed between the tone control and the stock Big Muff recovery stage (Q5 in this project).

This kit contains the PCB and all necessary parts. The enclosure can be selected, please select 4 knobs for 6,3mm shaft separately.

This project is by Aion Electronics, in collaboration with Musikding. If you have any problems with the contents of the kit, please contact Das Musikding (Klaus). Since the modifications require some basic knowledge, this project is rather for more experienced builders.
