Eventide Factory TDM confused

Hi fellow PT users wondering if someone could shed some light here on the above plugin. I've had this for quite while now but have never really used it in a session can never really seem to find anything usable. Its probably my fault but all the presets have strange names and just seem so over the top sound wise that it just seems impossible to pick one that needs tweaking for the usage I'm looking for. For years I've heard people talk about the infamous Eventide sound and how industry standard the H3000 hardware was but I could really do with some help with this plug in what presets are good to start with and tweak?? What preset is the infamous eventide sound?? I'm totally lost on this one. Thanks inadvance :)
