I learned to solder when I was in grade 8. At first, it seemed kind of stupid and I really didn't have all that much to solder. But then I became an adult and developed a problem with synthesizers. I bought a broken Juno 106 on eBay, got it shipped, opened it up (because hey, it was already broken) and was excited to find that all I needed was a soldering iron. A few minutes later and holy bass...
Years later, I moved into a smaller place and had to part ways with most of my synths. Sadly, my 106 was a casualty (since a Juno 106 is basically an eviction notice with a keyboard attached), but I sold it to a wicked musician who made some amazing sounds with it.
I still miss that instrument. I hate spelling fat with a 'ph', but the Juno 106 can only be described as phat...
