Guitar Leads Review

When I was a teenager and wanted to play the exact Clapton or Hendrix lead riff I would spend hours with a record and struggle to play it over and over. There was no capability to slow it down unless you could afford a reel to reel tape player. If you could slow the record down it was to 16 1/2 r p ms and now it sounded like Darth Vader underwater.

Now you can slow it down and still hear it in pitch.
