Hi,
This is my first post, and firstly, I would like to say that I have learn quite a lot from Justin and the lessons put up on the website, thanks Justin and Co.! I live in Singapore( I hope you know where that is,

) and guitar gear can get quite expensive, so lessons from a teacher would be adding to cost but the website has helped me a lot! Thanks again!
Regarding Arpeggios, are they only limit to these shapes and the Caged system shapes? What I'd like to know if I can use specific scale and areppegiate that. Example, I have been going through the Blues lessons and have learnt the first shape of the A Minor Pentatonic Scale. Is it possible to somehow manipulate this scale to play an arpeggio? I have tried using the whole scale, and it kinda sounded either 'scale-ish' or just plain crap,

.
Not sure if if made any sense, 'cause I don't really have much background theory and stuff. I've been planning to buy the Practical Theory book, and might be purchasing it soon

.
Thanks!
