But, the solution is to just use a gate. You end up using a gate on the rack stuff, too. If you try to turn off the gate on those units, you'll hear just as much noise (probably even more) than with pedals.
A couple of points:
1. "Just use a gate". A noise gate is the absolute sledgehammer of signal management; it is essentially a capitulation against your sound, where you say "everything below this level is complete crap, and thus I shut it out". So, noise gates in and themselves are a bad sign and should never be taken lightly.
2. "
If you try to turn off the gate on those units, you'll hear just as much noise (probably even more) than with pedals." Sorry, but what a nonsense statement. What causes the noise in the signal chain are A/D converters. In a multi-effect unit there are 2, one for input, the other for output. In-between everything is digital and thus suffers no signal degradation. In pedal world,
each pedal has 2 A/D converters, which means you're stacking up noise over noise the more pedals you concatenate. Sure, if you use 3 really high-end pedals and compare it against one really shitty multi-effect you might end up with less noise with the pedals, but in general the multi-effects are better with signal degradation.
The problem of multi-effects
used to be that they tried to Jack of all trades, master of none. That's essentially the only valid reason for going for pedals, since they focus on doing one thing right. But, I think that criticism against multi-effect is no longer really valid either, since units like the Axe-FX have phenomenal effects, and on top you get software updates that continuously improve the sound.
