As a former guitarist, I think guitar players are equally as savvy as bass players, but they only talk about it with other guitarists.
Guitarists obsess over tone. Which tubes produce the right amount of tube breakup and when. If you know one that plays a tube amp, ask him why he uses those tubes and you will see.
They also can tell you the difference between distortion and overdrive as well as why and when you would want to stack them. They obsess over the brown sound as well.
Don't get them started on the Strat vs. Les Paul discussion as that will start a holy war.
Then they will talk about guitars with different scale lengths, why the reverse headstock will give you the Jimi Hendrix sound because it changes the tension on the...
They also obsess over pickups, volume and tone pots, bridges, nuts, tremolo (bigsby, Floyd rose, lever, locked, floating)...
I would go on, but I think it would bore you.
... But this is why a guitarist can come into a room, plug in and play.
Bassists have a different set of worries. We have to tune our low end to the room. We can be too boomy if the put us in a corner. We won't be able to hear ourselves of we're too close the the amp, we may have to adjust to cut through a mix. I think we have to be more room aware.
