I've been recording as long as I've been playing (I started learning guitar in my early teens in around 1980). I bought my 4-track recorder in 1989 and used it until I bought digital 8-track in 1997. In 2003 I moved to tracking and mixing on PC. My home studio has evolved along the years rather a lot. Mostly by adding more gear. My current setup is roughly
