I go for a VERY tight and chunky defined rhythm sound mixed between old Anthrax, Lamb of God, old Exodus, Metallica, Iced Earth..etc.
I understand that the widebody is geared to be voiced for more of a vintage or open loose kinda sound, but in my opinion, if I didn't have a 2x12 recto cab to play it through, I'd still be completely happy playing through the 1x12 C90 for tight chunky rhythms even with the open back!
But there's 3 other things to consider: Technique, guitar and amount of gain/drive.
You should have a really good feel for the sweet spot between the bridge and the strings to get that chunk. Pressing a little harder with the palm will bring it out.
When I play my stock Ibanez Prestige, I do NOT get the tight sound I'm after, close but no cigar. When I play my Les Paul Custom with a Dimarzio Super Distortion, I completely GET it. So keep in mind wood and pickups. I will try new pickups in the Prestige and see how much of a difference it makes, but the wood is truly important.
Also, you don't want over saturation, it gets worse from there. Work your way up from a really dry sound while testing your sounds 1 notch at a time. You'll find when you have enough of saturation, you may want to pull BACK a notch on the drive/gain then pump the volume a bit and put the tubes to work. That's when it all starts to come together.
One last note, I used to live by putting a ts-808 tube screamer in front of all my older amps to tighten it up (low drive, high tone, low level) -- that always pissed me off because if I buy an amp, I want to use it for the sound it gives, not to always say "oh it will sound even better once I put my tube screamer in front of it" -- but ever since I got the Mark IV, I don't need it anymore, so to make it official, I sold the tube screamer. I'm weird like that.
Anyways, these are things that I've noticed that really helped me and others and hope it can help you in some way. Good luck!!!!!!
