I've been playing guitar since I was 13, and throughout my teen years I didn't give a crap about any other instrument. As I got into my 20s I began to like other instruments, like flute, tin whistle, sitar, tamboura, and pipe organ. I got a synthesizer pickup for my guitar so I can simulate those sounds on my guitar. But it would be great to learn the actual instruments, but I'm a) too poor and b) too lazy.
