Hi. This is a noob question I think, but since there’s some fine experts here I’m not afraid to ask a stupid question, since I want to understand better what I’m doing.
I’m prototyping the 4xDecay by Barton Musical Circuit. Simple, efficient. It’s working great.
I want to add an amount control at the output so I change the original circuit from this …
To this …
So a few questions :
- Can I replace my 10k resistor before the output variable resistor by a 1k? I think I’m understanding that the purpose of this resistor and the one before the LED are too “split” the signal between the LED and the output?
- Putting a variable resistor at the output is it enough to make this “amount control”? Should I add an op-amp to buffer it and a 1k resistor right after?
Thanks by the way. I hope I post in the right section of this forum.
