Hello Everybody!

Have you ever wanted a stable connection between breadboard and component

(That won't come out when your testing)

Have you ever been tired of cables that won't fit in breadboard hole or

pins that were just too big?

Have you ever wanted to make guitar effect but you had no soldering

skills?

If yes this tutorial is a right pick! :)

I'm going to show you, how you can make metal simplex fuzz while using screw terminals.

Why would you make one?

It's a great beginner project and also it sounds great!

(And you will stop having problems with potentiometers and jack sockets on breadboard)

Why I made one?

Every time I was testing a device I had problems with bigger electronic components. They were just

falling out. Even if they were sitting in I still sometimes had little disconnections which were ruining my life.

What do you need?

Breadboard(I used a really cheap one but I think it can be any breadboard)
4 screw terminals (triple kind)
All part mentioned in schematic(You will find those easily in any electronic shop)
Wires (I used ones from Ethernet cable)
Some spare time

So let's get on with it! :D

Step 1: What's the Goal? (Let's Start With Schematic)

Here is the list of electronic parts that are one the schematic:

(Picture 1)

resistors: 10k x3,100k x1
capacitors: 10uF x1, 0.1uF=100nF x2, 0.01F=10nF x1
pots: 100k type A x2(I'm using 1 because I don't use the volume pot), 50k type B x1
transistors: 2n3904 x2
diode: In schematic there is a led, but I found out that that are lowering the output so I used common diode: 1N4148
9V battery connector
9V battery

Also I made a breadboard circuit schematic which is made exactly the same as I made it on my breadboard.

(Picture 2)

This is the way you should connect it on your breadboard.

When you will be checking your circuit also check it with schematic (Picture 1).

Just in case you don't know how the breadboard connections look I posted an image.

Step 2: Preparing Sockets

After you found out how does schematic look , start off by taking screw terminals , pots and jack sockets.

When connecting potentiometers simply put the legs inside the terminal and tighten the screw.

When connecting jacks first bend the side that you won't be using (I have showed that on picture).

Then bend the legs a bit towards the middle leg (Just a bit don't break it ;) ).

After that make the same steps as with the pots.

If you made 2 pots and 2 jack assemblies you have finished that step. Your getting closer to the finish!

Step 3: Lets Make the Circuit!

Lets go back to the schematic. Connect everything (components ,cables etc.) . In program I had only double screw terminals but you should use triple ones.

There is not much to say. If you have any problems post msg. below. I'll answer as soon as I can.

If you have done everything lets get debugging! :D

Step 4: Testing

Plug the input and output jacks. Turn on the amp but have a finger on the off switch just in case something disconnected or you just made a mistake.

If it fails to work us multimeter with diode tester (the one that makes beep sound). Here are steps you might take to fix your circuit:

Test all the connections. (multimeter)
Be sure that you made all the connections right
Be sure that transistor is situated correctly
Be sure that battery is not discharged

If it works, you're done! Have fun playing with it. Really good job!

Also If you have any problems with that circut or u want me to make some other cool electronic project please post below. All coments are welcome. Thank you for reading:
