The Vortex is an interesting combination of familiar building blocks. It starts with two Tube Screamer drive stages with variable clipping options. From there, it goes into a Big Muff tone control stage. Using two CD4066 switches, it selects between two different sets of low-pass and high-pass filters used on both ends of the tone control. At the end, there is a gain recovery stage.
This kit contains the PCB and all necessary parts. The enclosure can be selected, please select 4 knobs for 6,3mm shaft separately.
