I wasn't planning on making a section for these but here we are...
The At Action Perk is sort of my take on the Harmonic Percolator
This one stays fairly true to the original, though it has an added clipping toggle for Silicon/None/or NOS Ge diodes, along with some minor tweaks.
Tuned for just the right amount of chewy bite and snarl, featuring a National 2n3565 paired with either a Central 2n404a or Soviet 1T308B. These clean up quite nicely with the instrument volume control as well, especially with the diodes bypassed.
There are currently 5 available. All different colors. One glows.
