I have a question: I didnāt get why sometimes there is the G note in A7 (6th string) and sometimes not. Thanks 
ps. i donāt know why, but I cannot leave comments in the āDiscussionā section under each video
I agree and have the same question, thinking there could be a slight mistake in the chart in bar 15 (GP-chart as well), as A7 should go down to the G note. Thanks for everything Justin, only a teacher like you could convince me to try the Arpeggiator and (maybe) find an error, lol 
Hi Justinā¦ I can download (and open) the arpeggiator pdf file but I cannot open the arpeggiator extended file when I try to open on my device. Is there any chance you could put a pdf version on the site? Great site BTW.
Welcome to the forum John
The GPX file is a Guitar Pro file and is the same as the PDF file. So if you donāt have Guitar Pro you canāt open it.
I guess Iām leaving then. This is just another rip off Web site that pretends to help by only giving enough to wet ones appetiteā¦ Then the cash cow is revealedā¦ Goodbye
Your loss. Justinās site is 99% free and so was the PDF file you down loaded which is exactly the same as the Guitar Pro file, which he provides for free so people who have Guitar Pro can load it up.
Justin has no affiliation with Guitar Pro.

Hi John,
Oooo, you canāt be more wrong than you are right now. Do yourself a big favor and look around the website a little longer, remember this post and thank me later. This site is not a money grabber,
Greetings,Rogier
@Johnlee , you may be jumping the shark a bit here.
If you are a registered (free) user of the Justin Guitar website, there is a pdf you can download as well as the guitarpro file (which naturally requires guitarpro).
All for free.
Just in case, here is a tab link:
(You may still need to be registered and logged in to use it, not sure)
Overall, Justin is the absolute LEAST money grabbing, spamming or otherwise disingenuous site about learning guitar you will ever find. Quality, kind, more than fair, giving, supportive and comprehensive are adjectives that come to mind.
We would love to have you stay and learn with us, and you will regret abandoning such an excellent program just because a download requires an app (which it does not try to hide). Give it another thought.
I encountered now the same issue, as @Urs and @Armi already wrote. If you go to the G in bar 15 the exercise continue like in bar 18 and you skip the two bars 16/17.
I didnāt looked up the sheet but after trying it just systematically I got the routine (with the G in bar 15) and thought it might be a good idea to play along the gp file - clash!
Okay, I can just use a metronom BUT @JGAdmin is there any better value to exercise the āwrongā version instead of the straight-with-G-version?
Hello and goodbye John. @Johnlee
As @stitch explained, the content of the pdf and the gpx files is identical.
Two formats of the same thing giving people the option to access it - for FREE - in one of two ways, depending on the computer and software they have.
The Arpeggiator, Revisited.
Among other Blues related endeavours, Iāve been plugging along with consolidating and expanding my arpeggio competency over the last couple of years; itās a journey for sure.
Arpeggios are usually part of my weekly practice routine in one form or another; mainly Major, Minor, Dom/m7, and more recently m7b5/ dim7.
My arpeggio practice may take the form of musical progressions in various positions, sometimes in isolation, sometimes in combination with other forms (triads, scales etc) , or via learning a set piece/song that has a particular arpeggio āthemeā.
In the last 6 weeks, Iāve been re-acquainting myself with Justinās quite demanding āThe Arpeggiatorā exercise.
Armed with much improved skill and experience since I first encountered it about 2 years ago, Iām finding the Arpeggiator to be very beneficial these last 6 weeks.
Iāve been expanding on Justinās original Arpeggiator exercise of 8th note I7 to IV7 drills, to initially include the full 145 progression, and utilising different divisions like triplets, 12/8 timing etc.
And itās a musical exercise regime that can have limitless permutations. Eg Start on the root note/3rd/5th/b7/ 2nd octave, reverse etc; start in different CAGED positions on the I; introduce other bluesy progressions, like ii-V-I, I-VI-ii-V, drop in diminished chords, use a ii-V-I within the I-IV movement etc.
The greatest overall benefit thus far has been a notable improvement in being able to really start to see and hear the arpeggios in real time scenarios, and being able to enter them from any note; with the internal triads lighting up nicely at times in many of them.
Being forced to jump from arpeggio to arpeggio under pressure, after a certain number of beats, and in a particular direction, can be challenging initially, but so worthwhile; and it does become easier with focused practice.
I feel like Iāve moved āup a levelā in the last couple of weeks with arpeggios.
Itās not instant satisfaction at all times, thatās for sure. It can be a grind at times; but this second round effort is starting to pay some significant dividends; and its carrying across to chords, triads and scales etc. Iām finding myself thinking a little less at times, and just playing. Itās a satisfying feeling.
Iām finding too, during my improv practice, that these arpeggio/triad/ scales are starting to seamlessly blend all together more often, like a single unit, which is very pleasing.
For anyone who knows their arpeggios a bit, and might be looking for a worthwhile musical arpeggio practice ( having tried numerous ones on the web), the Arpeggiator has re-emerged for me as a winner.
May be well worth a look for those at a similar level/ situation. You can find it in
Grade 7 >Blues Lead 4 > Making The Blues Changes.

This really made me smile, Shane 
Iāve always admired your dedication to practicing and playing guitar, and it is so satisfying to see you enjoying the fruits of your efforts. I freely admit to feelings of envy at times (a certain amount of āI coulda been a contenderā) but am very aware that path is not the one for me.
Thanks for sharing your journey and long may it continue

Kind words Brian, thank you.
And a ācontenderā you certainly are.
If music is about anything, itās about reaching out and engaging with others meaningfully; making them smile, or laugh, or shed a tear; and in that regard, you are near the top of the pile my friend.
Now, go and eat your vegies, and try out that Arpeggiatorā¦
Cheers, Shane

The āinsect-lovingā part of me is tempted to explain to you why you are wrong, but this is not an anthill I am willing to die uponā¦
Save me, Rogier! 
More importantly, I still canāt get the āarpeggiatorā working and may have to revert to consulting YT or the like

You were just wondering how you could involve Silvia in somethingā¦this would have been a great opportunity. Richard has written a clear piece about chit chat in lesson-related topics
ā¦ DONāT DO THAT ā¦ bad boys, bad bad boys 
And you are 100% right Brian (itās annoying to give a compliment twice in a row in 2 minutes )
