As always a more long term solution to fretboard navigation is to see arpeggios as INTERVAL shapes rather than note names - as these are universal to all scales, arpeggios and chords rather than specific to one particular root note - with this in mind the intervals for the C major blues scale are detailed below in the
CAGED4BASS manner:-

Once the individual box shapes have been assimilated all five shapes should be linked together and played in one continuous exercise (with the first shape - 3C* - being repeated at the 12th fret).

The video shown to the right demonstrates the CAGED4BASS chain-linked sequence for the C major blues scale box shapes.
