Hello Dan,
I am 43 and a total novice lefty, just got my first bass (Ibanez SR300L) 4 string.
I don't know how to read music/notation, I have no musical experience at all.
I am a slow learner and will need a patient tutor.
Where in Cambridgeshire are you based? I am near Hitchin in Bedfordshire.
Can you help?
