Heh heh heh... Hey I think I've asked before, but what do you use in lieu of 
BBD's? Springs, phase-shifters and digital stuff? I confess I have a 
fondness for spring reverbs - I just wish I did before I got rid of my Ampeg 
VT-40 *sob*.

I have 2 phasers: One a digital Boss PH-3 and and analog DOD FX20B (which is 
a six-stage OTA deisgn, the -C is a 4-stage so lookout) and though I tend to 
prefer them better than a BBD-based flanger, damned if I can get a decent 
FET-type flanger sound like a Phase-90. I wonder if the EH Bad Stone would 
measure up. I have a 4009UB just waiting... The PH-3 is always on the verge 
of promising, but comes short of delivering every time. It's great for 
screwing around though, the step and the rise and fal settings have 
potential for great weirdness...

But I digress...

What's in your gear, Harry?
