Yep - me.
Sax, wind synthesizer, flute, guitar, bass, keyboard synth, drums and vocals. Mostly tenor sax but I can play them all.
Drums were my first instrument but sax is my primary instrument. Wind synth is sax related as the fingerings are almost the same but playing technique differs from synth patch to synth patch.
I don't always practice safe sax. And yes, I'm a sax fiend and sax addict. I've been told I'm good in the sax too.
In my current duo http://www.s-cats.com I play sax/wind synth on almost 2/3 of the songs, guitar on about 1/3 and depending on the night a few with the flute. Oh and I sing about half the vocals. The ratio of sax to guitar depends on the audience and the songs that are working that night.
It's easier to read music on the sax than the guitar, but it's much easier to transpose keys on the guitar. Each instrument has it's easier and harder features. Voice is the instrument that took me the longest to learn well enough to perform on-stage without embarrassing myself or getting the band fired.
My screen name is "Notes" because back in the Jurassic era of the Internet, when we discussed things on usenet/newsgroups instead of these forums, there were already 3 people with my name on alt.saxophone (but I'm the genuine one). One called himself Bob, another Robert, and a third Bobby so I chose the nickname my sister's business partner called me, "Notes" and it stuck. (Stuck notes?)
So this Notes likes to play notes past the 12th fret, sometimes two notes at a time, especially if the guitar has a 25.5" scale because the notes are too close together on shorter scale guitars and Notes has a hard time those playing notes without fretting out or hitting the wrong note. This might be noteworthy to some and others will hardly notice.
