Without the other instruments, it actually sounded somewhat close to my natural sound. But then when we all played, I felt like it wasn't quite as sharp and it might've been just a touch mid-muddy. I was also getting some chimey-ness or overtones that I don't know how to clean up. My problem is that I don't have enough experience with EQ'ing other than lots of fiddling and no one else on our team does either. Any thoughts?
Sounds like you're on the right road ...well done! A few thoughts, since ya asked

1. This is a biggie: make NO sonic assessments based on your wedge! All tonal changes you make are to benefit your
house tone; this is what truly counts, right? You wedge really is just so you can hear yourself; sound quality is "welcomed" but not truly a must (I know, that sounds like heresy). If you want better tone for
you, you can get a better floor monitor, or perhaps first try EQing for solely
your monitor send (which you can do with your X32). But make all sonic judgments and adjustments listening to the house PA.
2. Try your best/favorite Venue settings with the guitar's bass control dialed back, try around 10:00. On my ES2 this helps attenuate that boomy bass, reducing some of the "mush" at the bottom end.
3. The pick noise on strings is both playing style as well as pick dependent. To the former, think about the angle of your pick to the strings, and of course your attack. This is no indictment of how you play, mind you! It's just that some things we do are tonally subtle or even indiscernible when playing unplugged, but introduce amplification and that which was insignificant suddenly raises its ugly head. It is no wonder why creating a genuinely good-sounding
recording of an acoustic guit requires skills acquired over years. You can try a thicker pick, but that may require adjustment on your part, so that may or may not be a change you're willing to make, but it's worth a try. Also, pick noise is akin to siblant "sss" and "tss" sounds when one sings: that's upper frequencies. So judicious attenuating of 10k will mitigate some of that. But
all EQ is a compromise: attenuating 10k to reduce pick noise may also lose some of the "sparkle" and note definition. Finding the spot that works best for you is your goal.
4. Anyone who's played live for any length of time knows there is the tone they like, and then there is the tone that
works with the band. Don't be surprised that the tone you like when playing alone gets buried as soon as the band kicks in. You'll hear the phrase "lost in the mix" commonly attributed to this bugaboo. It's normal. Each instrument occupies a sonic footprint. So when alone, you're diggin your sound. Then the bass, drums, keys come in and you've now got lots of "feet" overlapping and overstepping each other on the dance floor, so to speak: yeah, it can get messy! Which is also why some live mixes sound like a wall of indiscernible mush, so a guy turns one channel up to "hear him better" and things just get progressively worse! Mixing for an acoustic guitar within a full ensemble (the FOH guy's responsibility if ya have one) is a whole nuther ball game as your guitar's tone now must be "narrowed down" so as not to conflict with other instruments, as well as shaped to punch through the ensemble. It's a skill that gets you heard without turning up the volume. Same with the bass, keys, etc.; same with multiple singers. Once you learn this (or the FOH guy nails it), you sound like a proper acoustic guitar. Then take the band away and you'll likely think your guitar's tone is thin and harsh. Welcome to playing and mixing live.

So while there is
lots of nuance here, may I share one basic truth:
cutting bass frequencies
adds clarity. I'd be willing to bet that touch of "mid-muddiness" you're hearing is that 500-800Hz mid-bass that is getting layered with each instrument. Even the singers. Visualize a Venn diagram: keep adding circles and those intersections are gonna get awfully crowded! Fwiw, my standard go-to move is drop some 600 on vocalists, a little bit on some mics, a lot on others, but rarely do I leave the 600 flat when there's a
full band. But one singer and piano is a world of difference since these two instruments each occupy a larger space than each individual in a full band whose voices get summed.
5. The "chimey-ness and overtones" you mention has me a bit confused as to what, exactly, you're referring to. Too "glassy" at the very top end, maybe? If so, that is not unlike the pick noise you're getting. Again, that's higher frequencies so that's 10k (and up, really) so maybe this will sound better as you think through #3 above.
Hope that gives you a few things to think about and try. Chime back and report yer findings!
