This kit is designed for the guitarist who likes to improve their own gear.  If you've ever changed pickups or a pot in your guitar, you CAN do this!  Even if you haven't, this kit would be a great place to start.  You'll make a major improvement with your pedal, AND you'll get a great, easy to understand, introduction to the world of electronics! 

Here's the really good part -  you get an extremely informative 17 page booklet loaded with easy to read, full color diagrams.  Since wah wah pedals are the most notorious tone killers, the booklet covers them in great detail.  All of the most common wahs are covered.  Want to add an LED to your wah (or any effect)?  This booklet tells you how.  And to top it off, I've included instruction on how to build your own true bypass loop box w/LED indicators!

This version of the kit includes the 3PDT (3 pole, double throw) footswitch, booklet, and your choice of red, green, or blue LED w/holder and limiting resistor.  These are not your "common" LED's either.  They are a special purpose type that are capable of drawing VERY little current,  yet glow very bright.  They are crystal clear when off.
