Hybrid reverb (two different chips)?

Just a thought: Making reverbs with the PT2399 has the problem that it doesn´t allow short enough delay times to avoid "echo-y" verbs. But how about making the earliest reflections with a BBD chip, and letting the 2399 handle the "later" echoes? Yes, i know, an extra chip, also a clock chip, risk of heterodyning, more complicated grounding, etc etc. But...

Genius idea or should I go get more reading done before posting dumb stuff? You decide...

Ok, I see that my idea was so revolutionary and clever that I left you all speechless...

What kind of delay time are you after on the short?

I had once contemplated a 3-BBD reverb that involved a variety of feedback paths and different clock times, but once I saw the recently posted Equinox, thought better of it.

The dual PT2399 Equinox seems to be the more elegant solution, both from a clock noise and cost perspective.  The PT2399 is cheap, and the clock frequency is high enough that it doesn't have byproducts as audible as a BBD does.  It also doesn't require a separate clock generator chip.

Your idea is not a "dumb" one, but it really falls into the category of interesting experiments moreso than practical solutions.

PT2399 can go as low as 35ms delay without latchup, or down to 25ms delay with a latchup protection circuit. That's more than short enough for reverb applications- even for the early reflections.
