this is a video of Stevie Ray Vaughan's Texas flood song to half speed. By slowing the song down you can hear the lead guitar clearly and cleanly so you can learn the guitar solo easily.
This guitar solo was slowed down with a program called Riff Master Pro.
Riff Master Pro lets you slow down any part of a song a little bit or a lot with a slider bar that let you control the speed of the song exactly. What is really great about Riff Master Pro is that when you slow down the songs you can hear the lead guitar solos more clearly it doesn't change the pitch at all. This way you don't have to re tune your guitar to learn the guitar solo. However one powerful feature of Riff Master is there is a none other slider bar that lets you retune the song if you'd like. What is great about this is if your guitar is out of tune with the song you don't have to read tune your guitar so the song is in tune with your guitar. Saves a lot of time and headaches. Other features of Riff Master Pro which helps you learn guitar solos is there is a built-in eight band equalizer that allows you to move the slider's in a manner that makes the lead crisper and stand out more while minimizing sounds in tones that interfere with hearing the lead guitar such as the bass.
