Question/Comment on the use of Y-Adapters:
It was my understanding that Y adapters were fine for splitting signal — you’d basically get half the signal to each down-chain pedal provided they were both buffered inputs. However, for merging signals, Y-adapters are not sufficient, because you’re shorting two zero-impedance output buffers together into a high-impedance input? You could still merge them together without a mixer using a passive circuit (such as a 5k Ohm resistor on each input wired to a common output).
Now, you’ve obviously gotten great results, so now I’m wondering if this is in fact not the case, or if it only matters in certain situations (noisy signal, high volumes, etc). Hopefully someone at EHX who knows more about electronics than I do can comment on this
