I've been playing bass for around 6 months now but it has been in the last couple that I have really pushed myself...blisters and all. I want to learn some more complex basslines and figured I start with some classics. I want to learn both "signed, sealed, delivered" and "Want you back". Which of these two would be most beneficial to start with. from listening to both songs and watching videos on youtube, I think that "signed, sealed, delivered" may be a bit easier to play. Any help is appreciated, thanks.
