Sort of the same thing I'm doing with the Jamman.
1/8th input into the headphones outlet on my CD player, the other end into the Jamman, and then the Jamman into the acoustic amp.
When you get the set up finished you set the Jamman for auto record, hit the play button on the CD player, already at the time mark to begin on, and have your foot ready on the stop record on the Jamman. As soon as you've passed the point of interest you hit the stop record and then you have captured the part to learn. Then you save it if you want or immediately go to slowing it down with the tempo tap.
But this method you show is good for getting the archive stuff. Since I still don't own a computer and don't know if I ever will, I'm happy for now with my CD method and the Jamman. But I can still take my work lap top home if need be. I just need a correct input to go between the computer and the Jamman.
On another note,

, I find that I don't like playing along with Jerry and much prefer to listen, stop it, try to duplicate it, relisten, stop it, try again, etc., etc.
Good to see that many of us are going about this stuff similarly, but in our separate ways. What a lot of people don't know about is the countless hours we spend working over riffs, trying to take what we thought we mastered the day before to then take it further today, and finally getting everything seamless. You can't do it in one sitting. You have to come back over the material many, many times, and then do it a few times with a buzz to capture the essence.
