Effect Pedal - Roberto-Venn

    roberto venn specialty pedal 1920x700 Effect Pedal


The Roberto-Venn Guitar Effect Pedal Workshop is a one weekend introduction into analog effect pedals.  The student will build a silicon NPN replica of the famous Dallas-Arbiter Fuzz Face used by Jimi Hendrix.

While it’s possible to simply purchase the kit yourself and assemble it for about half the cost of the class, the experience of learning from experts in the field is more than worth the additional cost.  Instructor led learning will eliminate the confusion that comes from trying to build with nothing more than a schematic and a wiring diagram.  And you will leave class with a basic understanding of how your pedal works!
