Ok, I've done a bunch of research on this, both here and elsewhere on the web, and now I need you all to chime in with your suggestions. I'm looking for a dirty rhythm overdrive pedal to leave on pretty much all the time. I'm using a Dr. Z Z28 primarily, and would like a pedal with a nice thick bottom, singing mids, and sparkly-but-not-shrill high end, and sounds very 'open'. I don't really want a pedal that will compress at all really. (That's a lot to ask, I know!). Any and all suggestions welcome. I have a few ideas myself, but I'm really interested in any opinions you all might have for this. Thanks!
