[sdiy] If I'd consider making a PCB for a flanger ...

Are you talking about a real thrue zero flanger
with lfo/manual control or standard lfo sweeping type flanger?

 ... what BBD would you prefer?

I get quite a lot of requests for making pcbs for the Storm Tide flanger.

I can't do exactly that , for 3 reasons:

(1) It uses highly obsolete BBDs
(2) It's too close to Eventide
(3) I know a lot of things I'd do differently now.

But I'm (vaguely!) thinking about a "Son of Storm Tide" as a future pcb 
project.

If I'd do this, I'd obviously not use SAD1024s.

I have a favorite vintage BBD chip of which considerable stock is left, so 
I'd design it for this chip.
I'd want to have a fallback strategy in case this chip suddenly gets 
extinct, and so my plan would be to offer a pcb where you have a choice of 
two different BBD chips to solder in. (Similar as I did with the different 
transitor arrays on the tau phaser.)

Now, I know what BBD chip option #1 would be (I won't tell right now, for 
obvious reasons ...)

Please let me know what you'd prefer as option #2. (Should *not* be another 
vintage / extinct specimen, but one of the modern parts.)

Preferred length is 512 stages.
