Hey dg,
I know exactly the sound you're looking for. Unfortunately the envelope on the MF isn't all too adjustable/versatile. To get that Lovetone Meatball sound you'd need a faster attack and a faster release or close or filter. The Q-Wah would almost be the effect to do this, however, until Eventide kick up the tweakability on the Q-Wah, we Radiohead enthusiasts are outta luck.
Check out Lovetone's website for some neat effects.
