I think the tone in Smoothie Song is the best example of an effected upright sound.
I used to think it was an envelope filter but the sweep at the end of the intro is making me think it's a wah.
Does anyone have insight on how they got this tone or have gotten close to replicating it? There was probably plenty of studio processing going on but you must be able to get close with pedals.
Im guessing the bassist was Byron House but it could have been Edgar Meyer
