Really worth having a play around with.
Even if you just remember the places where you use all four finger and add those bits to your playing with the standard Blues Scale or Pentatonic Scale. That will make sense when you see the dots :-)
Below I've mapped out versions based on adding notes to the conventional Blues Scale boxes and also versions that change those slightly but avoid some of the longer stretches, just decide for yourself what feels better under your fingers.
There's also some bonus Blues Shred Monster three note per string versions right at the bottom if you fancy a go at that sort of thing.
