When I started playing guitar there were no tabs, Audio Chord Wizard, Internet or anything like that. Back then the only way to get the chords was to either buy the music or pick the chords off of the record or radio. Since sheet music was expensive back then, at least to me, I had to pick the chords off the radio/record then buy the Hit Parade magazine for the lyrics.

I still practice that technique but I also use the ACW. Like Matt said it is a tool so why not use it.

Whenever I get something stuck in the back of my throat, I dislodge it by drinking a beer.
It's called the Heineken Maneuver.

64 bit Win 10 Pro, the latest BiaB/RB, Roland Octa-Capture audio interface, a ton of software/hardware
