Gadget #2 that I got recently is the Line 6 Toneport UX1.
This is a guitar input device for the computer. It allows you to play the guitar and record the sound, live on the computer. You can then edit this sound, add sound effects etc, to make your own songs. It also has a bunch of built in amp models that allow you to simulate playing your guitar through different types of amps. Essentially, it turns your computer into a 'super-amp' where you can perform all kinds of cool effects on the music. I'm having a lot of fun playing with this device as I practice the guitar. I've been bad about practicing the guitar lately, but thanks to this cool little toy, I'm getting back into it. Maybe one of these days, I'll even be able to play this thing!
