Sequencing the minor seventh arpeggio is a much easier job than with any arpeggio consisting of only three notes. In this example I am using both sweep picking and legato to get the job done. Don't let the stretching hold you back. Once you have decided to master it, it will become as easy as anything else. After you have played through the tabs and can remember the lick, practice it with 1000% control, making NO mistakes and then put in 10.000 repetitions before you pass judgement on your own ability to get it up to speed.
