This is a an amazingly good sounding fuzz-unit! It's easy to use,and easy to build into
your guitar if you like! Only three transistors! With the guitar volume it's easy to get
different levels of distortion.A really smooth unit!

One problem though occured while testing it on my solder free deck. A bad sound was heard!
That's because of bias problems. I had to replace the 100k resistor at the first transistors base with a 100k trimpot
Then it was easy! Slowly turning and...there it was! the good sound!
