The Singularity is basically the fuzz section from the Black Hole Symmetry which is unique is sending the signal through a JFET transistor then 3 silicon transistors to end up being destroyed!

The Singularity keeps the look and fun of the Desintegrate setting to a single output volume control and adds a 3-position toggle switch to cut the output Low-Pass filter at 3 different frequencies.

3-position switch: Low-Pass filter frequency at 1.5 kHz (BHS style), 3.3 kHz, 16 kHz."
