Noisy Bypassed Models

[Drybonz]

I just picked up an HX Stomp, and I'm noticing that bypassed models (effects) are introducing a bunch of noise while they are bypassed.  Any way to fix this?  Thanks for the help.

If a bypassed block seems to introduce noise, it's because it is set up in a way that attenuates the signal when it's engaged.

Thanks for the reply... my main question is how do I prevent this?

What models do you notice this with, and what is your setup?

Quite a few... most recently the auto-swell is really bad... also the mutron clone.  My setup is pretty straightforward... some pedals into the HX stomp into an Alto speaker (or sometimes Mesa amp, but not since I've had the HX yet).  Let me know if you need other details, but really it's just some bypassed effects that are a problem... nothing else is causing problems.  For instance, if I bypass that noisy auto swell, it's very noisy... then if I turn it back on it's really quiet.  I don't want to just remove the auto swell because it works fine when it's on... it's just the bypass causing the problems.

 

Thanks again.

It's basically what @Schmalle said above. The noise is there normally, but the blocks are hiding it. Both of those blocks you mentioned are envelope controlled, meaning their output depends on the level of the input signal. So they act like a noise gate with low level noise - they're blocking it. You could turn the noise gate on in the input block if you want. I'm not a huge fan of noise gates, personally, but they have their place. If you're using a high gain amp model, it makes sense.

If you want to be really fancy you could set up a noise gate that turns on when the effect turns off and vice versa.

I had some general noise problems I'm working on, which should help some.  Thanks for the advice, guys.
