I have loads of jazz bass books listing all the scales anybody could possibly need. I have good finger patterns for most of these, but not for the diminished scales.
Can anybody help with a good finger pattern without too many shifts?
I think it's easier if you shift a lot. I don't know if it's common to do it this way, but I just play 2-4, 2-4, 2-4, etc. going up one string. Ex. A-Bb, C-Db, Eb-E, F#-G
