Hannibal is an overdrive pedal derived from the GCI Riffchild. Experienced builders will recognize the topology as a negative feedback op amp clipper — arguably the most common type of circuit used in overdrive pedals. Despite being fairly common, it’s an excellent sounding and highly customizable circuit. This PCB is an easy build with minimum components, yet it still offers the builder enough flexibility to tailor the tone to their own tastes.  

Sale is for PCB only.  You must source the components and build the pedal yourself.  To make foot switch wiring easier, we also suggest you buy the 3pdt utility switch.  

Build documentation can be found here below.  Please read before purchasing.
