Looking for any other bands that either use synths or Halloween styled synths and are doomy like Acid Witch or are Doom Metal-ish and have psychedelic sounding guitars. There's gotta be some out there (or at least you'd think). Harsh vocals aren't a must but it'd be ideal. Thank you in advance

Abysmal Grief come to mind. it's a mandatory listen, when it comes to Hammer-like Goth Doom:

And this lesser-known band too, Satori Junk
The synths come hafway. It's still quite somber, there's no tongue-in cheek attitude in there...

Veteran Italian Jacula are certainly recommendable in this dark liturgical vein, it's more proggy and baroque. Not so doom per se:

Thank you! all super solid!

You're Welcome. They're all Italian btw, I didn't know Satori Junk were, but there's definitely something in this particular scene that leans towards the grotesque. You should check it more deeply.
