I think guitar is harder because you have to memorize the fingering for all those chords.
Obviously, playing one note at a time is much easier than that. So I'm sure it's not a big deal for most guitar players to switch to bass, as it seems pretty common. But really, bass requires a whole different mind set for approaching a part that a guitar player might not be able to fully get into if he wants to "up his bass game."
For instance, it's easy enough to do basic stuff like going with the root and locking in with the kick drum. Plenty of songs where I do just that.
But knowing when and where to put in subtle embellishments is a different story – ghost notes, grabbing a quick octave note, knowing when an alternative note or pedal-point could be used instead of the root, sliding up to the second octave of the neck for a few notes, then back down.
Sometimes I'll craft a part with notes that briefly chase a section of the melody line. Or a basic root part that briefly chases the
rhythm of the melody line. On songs like these I'll often move back and forth between that and following the kick drum with roots.
Sometimes the song feels like it needs a bass line that doesn't follow the kick or melody rhythm at all. For instance, tonight at rehearsal we were working on one I felt needed me doing a busy syncopated thing that was totally separate and apart from the vocal line or drums, and it worked great.
Another song we frequently play, I've worked out a syncopated walking line around jazzy licks / chords the guitarist does, again not considering what the drums are doing at all. He in fact, worked his part around what the two of us do. It sounds great.
Again, these are things you just have to have a "feel" for, and for the right song to do them. I couldn't teach it to anyone in a way that makes sense – either you know when and where it's appropriate, or you don't.
Maybe it's easy for a guitarist to fully "switch brains" into bass; I don't know enough guitarist / bassists to say for sure. But it seems to me like it wouldn't be easy getting beyond basic roots and kick drum.
