Yep, I love playing nerdy jazz and fusion guitar with lots of fancy fast and esoteric crap, and earth shaking rock, funk, and reggae bass, the simpler and more in your face the better. Each of these scratch a unique musical itch, along with writing and producing and horrendous keyboard playing and noise making. I've always hated the sound of my voice, so I don't bother singing.
The muting issue is a good thing to focus on, it's often overlooked, and along with a strong, confident (dare I say bassist_like) attack, is key to sounding good on the guitbox.
A friend of mine who's a really killer trumpet player and solid drummer once said to me "I love how one instrument informs the other". Always liked that comment, its true, bass playing reminds guitarist-me that rhythm and groove is THE thing, and guitar has helped me be more melodic on bass, even if it's just a 4 note melody.
