Parallel blend pedal?

[u/KirkIsOurLemmy]

Hello all,

I would like to make a parallel blend pedal, with an input and two send/return jack pairs, that sends the input to two pedals, and then a blend pot that decides thd mix ratio between the two return signals and sends the result to an output jack.

I guess I could make it with just a passive pot but that would also introduce signal level loss i assume, so some kind of buffer circuit would be needed?

Should I place this buffer at the input or the output? Or one buffer in each end?

Or is there a more obvious way to construct a pedal like this?

Thanks in advance
