My band BigRoom are a mix of Americana, Country, Folk, Blues, Jazz & anything else old school & I find myself using the 2 Moog pedals & the chorus a lot (depending on the song for the way I use the Murf or bypass it).
My suggestion for a pedal would be a Low Pass Filter with a pedal.
It's good having control over how much top end is coming out. You can have a very muffled sound during quieter sections & open it up to fetch out a fuller sound for choruses or buildups in bridges.
Try one first, see if it's what you're looking for.
