Using same BTDR-2H module for two different circuits

[abakuzam]

Hello people,

I was wondering around to build a reverb for myself then i had a thought about using same belton module for 2 different reverbs, let's say ghost echo and faux spring reverb etc. Is that logical? I was thinking to build a seperate power board for the brick to not deal with "switching every pin" stuff. Am i on the right path? Is it feasable?

I hope i'm not that terribly wrong on this one

I wonder what you mean by:

build a seperate power board for the brick to not deal with "switching every pin" stuff.

ghost echo means you need some kind of delay before your brick and faux spring reverb means you need just the brick itself (maybe with some filtering after the brick).

I designed a similar pedal for the firm I work for with electronic switching for the delay path.

I was thinking about switching all 6 pins with a simple switch wiring, then I thought it would be a bad idea to switch ground and vcc in every action, possible voltage peaks that may hurt the device? That's what I mean with "switching all the pins" , sorry for my lack of explanation. I was just thinking about making two circuits ( faux and ghost echo) and mechanically switching the brick. Like hot swapping. Can you explain me the switching the delay line? If that's possible of course. Thank you for your answer

Are you proposing having both circuits in the same box, switching between the two? Meaning, you can only have one on at a time? I don't see why that wouldn't work. Keep the power pins connected and switch the input and output pins. Not sure about the signal ground, may want to tie that directly to the power jack?

Follow another path:
instead of making 2 almost identical circuits, why don't just switch the "differences" between them?

Ghost echo is the same as faux reverb except it has a delay before reverb.
If you build one delay and one reverb and put them in series you can simply bypass delay for faux mode and engage it for ghost mode.
You obviously need 1 dry path for both delay and reverb.

Yes, that's what i was asking, i should try that and see if it works.

Thank you, i understood the principle, time study on schematics.
