Hey everyone I was wondering if anyone could help me out with possibly understanding John's mentality in the composition of BSSM, where was he coming from and who else can I look at with similar style. He's self admitted that his theory and ability was very high at this point prior to his drug addiction. I know he's sticking to a lot of the basics in some songs. Other songs he ventures out into modal play and it sounds like hes using a lot of dissonance on the album to help his sound.

One specific example I have would be this:
Intro
e|---------------------------------------------------------------|
B|---------------------------------------------------------------|
G|------0-----x-x------------------------------7/9-9-9-----------|
D|------0-----x-x--------------3-3-3-3-5/7-7-7-------------------|
A|------1-----x-x-(x3)-3/5-5-5-----------------------------------|
E|--1-3---1-3-x-x------------------------------------------------|

Verse
e|----------------------------------------------|
B|----------------------------------------------|
G|----------------------------------------------|
D|----------------------------------------------|
A|------------------------1h3p1-----------------|
E|--1-3-3-1-3-3-1-3-3-1-3-------1---------------|
"shoulda been, coulda been..."

Verse Pt. Deux
e|-----4-----4-----5---6--------|
B|-----4-----4-----5---6--------|
G|------------------------------|
D|--3-----3-----4---------------|
A|--3-----3-----4---------------|
E|------------------------------|
"Oh baby think you can...."

The intro and first verse are pretty simple G minor pentatonics, but in verse 2 hes doing some dissonant chord which chromatically goes to A6 and finished on a A#5(??).

I'm hoping to have some description on his approach towards his musicianship overall at this point. The example was exactly that.

Please help, I am in a very confusing and frustrating point in my playing which goes beyond this cry for help.

What he's playing in verse 2 it's not A6 and A#5, he's playing inversions of Fm7 and F#7. You should analyze what Flea is playing in order to really understand what John is playing. In this case Flea is playing F and F# on the bass.

I recommend you to learn or at least have some idea of what Flea is playing after learning John's guitar part. That way you can see how they relate to each other and have a better understanding of John's guitar part.

I'm not sure of what you're asking.
To me it sounds like he wants to a funky bass player but since they already had one, he's just playing the bass lines on guitar.
