Really i don't know how many chords you know?
Plus if you know how to use substitution chords?
Heres an exsample of useing a 9th chord in the place,
of 2 7th chords in the key of A .
Now if were playing a basic blues progression in A and were,
useing A7 D7 E7 for the progression we can use E9 D9 ,
over D7 and E7 .


D9
E[---------5------------]
B[---------5------------]
G[---------5------------]The Root note is D and;
D[------4---------------]its on the 5th string.
A[--------5-------------]
E[----------------------]
1 2 3


This chord is moveable so if you move up 2 frets you have E9 ................................
you can use dominant 9ths 11ths 13ths m9ths m7b5s ectect;When playing Blues.I also use alot of octave styles in my blues and jazz like useing the index and pinky finger.I played in alot of 3 piece groups where you,
had to play the chords plus the licks to keep the band sounding full...

Its great that you brought this subject up now mabee we can hear from alot more poeple about useing Substitution
chords..............
P:S A good book on Blues substitution chords could also,
help you .I used the Mickey baker jazz substitution chord,
book when started out years ago.Then i had the chance to,
to get around some great blues & jazz guitarests so i stole alot,
from them...............................lucky i guess.
