The DS Custom Harmonious Perc is our adaption of one of the most famous and highly sought after effect pedals in history, the Interfax Harmonic Percolator.
As in the original, the Harmonious Perc also uses a silicon and a germanium transistor (in this case a NOS Soviet one), and two germanium Diodes (we used 2 NOS Soviet ones in here).
To make it stand out and to make it work better in some applications, we wanted to add some more useful features to it, like the switchable FFB circuit, which makes it work better with Buffers in front of it. Also we wanted to add some more controls, like the Symmetry and the Sag control, and have the Diode Lift footswitchable as this makes it easier to control this in a live situation.
