I'm looking for something like an electro harmonix attack decay, or pigtronix philosopher king.
Or ideally something with the ability to get much weirder
As far as the swell/SG1 thing goes...I know the DL4 and Echo Park can do it, and so can BYOC's Slow Gear clone, the Lazy Sprocket.
In that departement I'd also go for the Guyatone though. Small and affordable, no frills. Not much extra noisy weirdness either though. Or the Malekko AD, which might be pretty similar, though I never tried one myself.
I bought a Pigtronix Attack Sustain, figured it'd be the end all be all SG1 swell machine. Really dissapointing, especially for something that pricey. Flipped it at the speed of light. As a compressor it's overkill for me, and the thing is about the size of a football field. It just sucked at the auto swell thing. I'm pretty sure it wasn't user error, and I read enough similar reports online to be sure that my unit wasn't broken or anything. The problem was that there was no way to allow notes to sustain naturally. If you'd want to let a note or chord to ring for longer than one second or so, it'd be cut off/gated completely. Really annoying, made the swell effect and the whole pedal totally useless to me.
The best I know of is the EHX (Bass) Micro Synth.
Also, Strymon Timeline and Mobius do this and lots of other weird stuff.
For the rest most of the pedals are mentioned I think.
