I play guitar and cello, but not bass. So this is a question for the ears of experienced bass players. On the song "All You Need Is Love" by The Beatles, off of "Magical Mystery Tour," I'm having a hard time hearing whether he's using a double bass or an electric. He’s credited as playing both on it, but you only hear one bass part. At times I think I hear the distinct attack and character of a double bass (an instrument I’m very familiar with). But it often seems to be played with the touch of an electric as well, and sounds like one. It’s very hard to tell which I’m hearing. I’m very familiar with the complicated history of the recording of this song, so I’m really not looking for any facts that people have heard or read about it. I’ve heard and read them all at this point. My question is this: Can I ask experienced double or electric bass players to please give this song a listen (it’s 3+ minutes) and tell me if in your opinion it’s an electric or an acoustic bass that you’re hearing (I've included a link to the song). The link below is to a video of the Beatles recording the song in the studio, which was simultaneously being broadcast live for television. The Beatles are playing against a previously recorded backing track which McCartney played double bass on. You’ll see McCartney playing his Rickenbacker bass, but it may actually be an acoustic that we’re hearing (with the Ric being mixed way down or out completely). You don’t hear two basses. It’s one or the other. http://www.youtube.com/watch?v=rLxTpsIVzzo Thanks a lot. I appreciate you taking the time to spend a few minutes listening and giving me a player's opinion.
