Make an easy guitar distortion pedal (STEP BY STEP!)

Step 4: Important Step: diodes!

Picture of Important Step: diodes!

http://www.allaboutcircuits.com/vol_3/chpt_3/1.htmlI will not go into detail with the diodes as you do not really need to know much about them other than what they do, how to connect them and some other stuff.

Diodes are used in circuits to stop electricity from flowing back into the circuit. They only let current through in one direction. The diodes in the distortion pedal are what make the distortion. Diode-clipping distortion is what this called!

There is a certain way to connect diodes. It is pretty straight foreward.
There is always some sort of line on a diode (except for LED's) but on regular diodes there is always a line. Like in the picture below on the left side of the diode is a line.


The schematic symbol for a diode is shown below:

You connect the diode with the line facing the direction the arow is pointing.

but is their a way to put them?
mikehayworth (author)  Undermig4 years ago
yes, there is a line on all diodes, (like the one above, it has a line!) and in my diagrams there is a line on each diode, so just put the lines facing the same way they are in the diagram!
o ok
and are they really small?
mikehayworth (author)  Undermig4 years ago

the lines, or the diodes? the diodes should'nt be reeaaly small but they will usually be about the same size as a resistor sometimes bigger sometimes smaller, but the line should be big enough that you can see it though.

ok well i am pretty sure the one i have is a diode i can see in the picture its the same thing but mine is very small
