Welcome to my first instructable and it's not very good, so consider yourself warned.
If you own an iPhone or an iPod Touch and happen to be a guitar player chances are you have already heard of either GuitarBud by PRS or of iRig by Amplitube.
Both products allow you to connect your guitar to your iPhone or iPod Touch and use it as a practice amplifier via their own apps or any others that can do the same. Isn't technology fun and useful? It's also expensive and hard to find especially in Portugal.
Inspired by these products I decided to do my own version, only much cheaper and not as nice looking. On the next steps I will try to explain how to make your own cable.
If you don't understand anything feel free to contact me or ask in the comments I will try to make it clearer.
Step 1: Things you need
Despite the street prices of these things they are actually pretty simple and cheap to make here's what you need.
- 1/4 inch female mono jack socket. This will be used as the input for your guitar.
- 1/4 inch male stereo jack socket or a 3.5mm stereo female jack socket. This will be the output, headphones go in here. I used the 1/4 inch because I had it laying around along with a 1/4inch to 3.5mm adapter, if you prefer you can use the 3.5mm and spare yourself the adapter.
- 3.5 mm stereo video cable. The most important part.
In the last picture you can see three cables the white one came with my iPod Touch and has a built in microphone, the black one are my headphones that lack the built in mic, and the grey one is the one we'll be making.
This is why we need the 3.5mm stereo video cable, it has the same lugs as the white one. One for the mic (in this case the guitar input), and two for the headphones (in stereo were available).
