ok, so i just got back from blasting through the Warp Sound.
I was trying to get that "Sometimes" tone using Shields' settings from this pic:

Setting up the Warp Sound like that and then into a Big Muff pretty much got that exact tone.
When playing chords it pumps out some heavy harmonics that seem to jump around with each strum.
i was also able to get this tone with some tweaking of the Muff:

When playing solo notes it gives sort of a buzzing fuzziness that sounds really great on bass guitar.
I also set it up after a Big Muff and was able to get all sorts of lo-fi, am radio, shoegaze type tones.
It sounds insane with slow vibrato and some reverb; you're basically in drunk tone heaven!
So I'm still getting into it, but this was a good good buy so far!
