Thanks for the replies! My middle finger measures just over 3" and my span(from thumb to little finger) is 8.5". I can play a little guitar and thought this was always holding me back, I really struggled with barre chords!
I'm new to the bass guitar and I'm finding it difficult to stretch more than 3 frets, seems impossible. It's quite disheartening actually! Is it just a case of practising or will I really struggle? I have a Fender Squier vintage modified 70s jazz bass.
