I got into guitar when I took an old door chime thingy - this hollow wood box with three steel strings on it with wooden balls on strings - and miked it up with my boombox and overdriven Radio Shack reverb unit. The hideous noises I made inspired me to build my first electric guitar, and then the second and third, and then a bass; and I started learning to play by ear with some help from a friend.
Eventually I realized I wasn't very good at making necks and fretboards and bought a proper guitar which I still use today. (I also bought a guitar from the aforementioned Jackman, which is great. It sounds so cheap and twangy, the opposite of what you usually hear, I love it!) Now I amass many megabytes of riffs with my Boss loop pedal with the intent of one day creating the Heavy Metal meets Mapleshade record that does not yet exist in the world to my knowledge. I used to have a bass too, but that's even more impractical to record than guitar. I also am nuts about electronic drums. I once bought a TrapKat controller, which cranked my appreciation of any human who can keep a beat with sticks into the stratosphere. It was an epic trainwreck of musical failure. The fingers work great, but swinging the arms and trying to tap the feet at the same time was painful to watch, had anyone been watching me.
I also have a clunky grasp of keyboard playing which also gives me a massive degree of respect for anyone who can make their two hands work independently. But usually whenever I play piano I forget what I had learned last time I played.
