What really is the difference practically between the Line In vs FX Return??
For example, I see that you can run the FM3 into either with the big difference being volume achieved. Is that the real difference? That the FX Return is looking for a lower line volume (pedal level line) so it’s increasing it more than the Line In (which is looking for line level?)
…and a related question…I’ve found that running a JHS PowerDrive distortion pedal directly into the Line In sounds fantactic!..which has me more confused because the JHS PowerDrive isn’t specifically labeled as a preamp. I guess this pedal just happens to boost the output enough to be used as a preamp into the Line In?
Many thanks in advance!!!
