The DIY Dumbloid Special, (or The Screamerloid is probably the correct name), by some strange coincidence sounds like painful hemorrhoids.  This pedal is an overdrive pedal and is extremely similar to the Tubescreamer.
This is the SPECIAL build version and includes the optional 1N4148 clipping diodes.

A description of the pedal can be found at and the information and veroboard layout for this kit can be found at
