Series Introduction

Welcome to Inside and Out with Jeff Marshall! In this lesson series, Jeff takes a bottom up approach to fret board proficiency. Using the CAGED system, he builds off of familiar open chord shapes to unlock the fretboard for not only chords, but arpeggio's scales and the beginnings of solo and improvisation. If you're looking for a better handle on the fretboard, this is the lesson series for you!

Jeffery has been a staple of the L.A. music scene for more than 30 years. Jeffery left his humble upbringings in Northern Michigan to attend Hollywood's own Musicians Institute in 1989. Upon graduating, he quickly immersed himself in the local music scene playing in a variety of bands, one of which included the band Hardware featuring Tod Howarth of Frehley's Comet, Ted Nugent, and Cheap Trick fame. In 1994 Jeff relocated to Dallas, Texas where he teamed up with alt rockers The Judas Engine and recorded guitars on their self-titled debut Rainmaker Records release. In the late 90's Jeffery relocated to Southern Ohio playing in various local acts where he further honed his craft as a reputable Blues/Rock guitarist. In the early 2000's Jeffery returned to the Los Angeles area and toured with a variety of national acts, which included Lisa Hayes and the Violets, and Pop/Country artist Ashley Jay. About this time is when he met Paul Vallis, the founder of UK's very own Bleeding Harp. Jeffery co-authored and produced Bleeding Harp's debut CD "Gotta Have", released in 2004. Bleeding Harp quickly rose through the ranks of the L.A. Blues scene, regularly playing venues such as Harvelle's, The Blue Cafe, The Coach House and the Catalina Island Blues Festival. In and about 2004 is when Jeffery met Country artist Rick Monroe. The two quickly hit it off as writing partners and Monroe's "Against the Grain" is a result of this pairing. Jeffery moved to Nashville and toured with Rick for a number of years, both in the U.S. and abroad. Rick's video of his Allman Brother's remake "Midnight Rider", which featured Jeffery on guitar and background vocals, was on regular rotation on country music's CMT. The group opened for a number of well-established acts including Dwight Yokum, Montgomery Gentry, and Kenny Wayne Shephard, to name a few.

In 2006 Jeffery returned to L.A. and began teaching at the world-renowned Musicians Institute, Guitar Institute of Technology where he currently resides as a full-time instructor. Jeffery teaches a variety of core classes including Single String Improv, Rhythm Guitar, Guitar Studio Skills, Rhythm Section Workshop, as well as private lessons. He has also written articles and created instructional YouTube videos for Guitar World Magazine. Jeff can be seen playing with guitar phenom Jeff Kollman in his solo group The Jeff Kollman Band and jazz/metal fusion band Cosmosquad at the world famous Baked Potato. He also plays lead guitar for season 4 of "The Voice" contestant Michael Austin in Michael Austin and the Law, which regularly performs at Gilley's Saloon in Las Vegas.

This lesson series is so well mapped out and taught so well I do hope he comes back with more!


amazing teacher!


Great stuff!


Best lesson ever


Everything above. Finally a teacher and FULL strategic method that ties it all together. Best teacher on Jam Play for those stuck at the intermediate level (hitting the dreaded barrier) knowing songs by memory and have rhythm chord playing do


Very good ,easy to listen to and understand ..


Excellent series! Please, do more lessons with this teacher!


Finally clicked in my brain for major Pentatonic with this lesson. Thanks


Great stuff


He's likeable and it starts in a way that is easy to understand. The only thing I'm missing is now some tabs of some exercises which I will make myself. It would have been great to deliver those in guitarpro format though :)


Totally enjoyed this series! Great job Jeff! The material is well-organized and easy to follow. Jeff gives some great tips on improvising and composing. Thanks again!


I don't know why the options here are using radio buttons, I could otherwise easily select multiple! But I guess that yes, in general, I absolutely did need this demonstration of the different boxes being connected together.


I have not idea, why, after years of hitting my head against CAGED, this lesson series if finally making it stick. It is because I know the concepts, but never put them together? Is it because of Jeff Marshall? I have no clue. But I did just "p


I liked the teacher. Easy to understand. It's just what I needed.


This course and Jeff's approach is brilliant( gee can you tell I'm excited!} From the simple idea of keeping the course in SAME key to his building on what was previously taught. I had so many lesson for example say - ok lets do it in ___ key,


I was able to chart out the system and jam in each of the CAGED positions with the aid of this lesson. Now to put in many hours or practice time.


I would have picked all three accolades if that was an option. Good course/teacher.


I'll check ?3 above boxes Did I say structured? Thanks


i'm hoping to improve my improvising and know i need to learn arpeggios. no short cuts!


Jeff articulates the concepts clearly and logically. It appears that this was recorded a few years back and is his only one. It would be great if he were invited back to do more (perhaps he was). I would certainly enjoy that.


Nice solo work. TY!


Really been playing rock and classical guitar for 62 years and finally understood the fretboard from your lessons… Theory the practical way: inside the head and out on the fretboard… TKS


Teacher is good with low key style


The instructor explained how to know which note is the root note.


The link between triads, pentatonic, and full major scales within the CAGED boxes and further harmonisation with chords is explained with mastery by Jeff. I had to re-watch 3 times in order to land the boxes with their respective chords but onc


This is the money shot that brings it all together.


this lesson is amazing!


This particular lesson helped pull together everything he has gone through in this course. I wish he had kind of done this at the start or told us to go listen to this part at the start and then come back and go through everything so that we u


This was great! Thanks Jeff!


What an excellent teacher Jeff is, I've been trying to get my head around this stuff for years!
