Fx Loop Noise

why fx loop makes so much noise? i try to run my wha cry baby on it but the noise is too loud

Check the position of the little switch on the back of the HD500, make sure it's set to "stomp" and NOT to "line"

 

The most likely answer is the problem is with your cry baby wah. Unless there is some hardware problem with your HD500, or possibly an issue with how you are setting the levels before / after the FX loop.

 

I am guessing your wah is not 'true bypass'? Do you notice noise when the wah is switched off?

 

The wah should be the *first* thing in your signal chain. One trick you could try, if you have to place the wah into the FX loop (example, if you are using a JTV using VDI to the HD500) would be place a noise gate right after the FX loop.

 

The second link has info on which Cry Baby models are which type of bypass wiring :

-H = hardwire bypass

-T = true hardwire

-B = buffered

-HR = hardwire relay

-TR = true hardwire relay

For example, if you have a "vintage" effect pedal that only sounds awesome when it's ON, but sucks the life out of your tone, or induces a bunch of noise while off, or does other problematic negative things to your sound, you could use a "true bypass" effects loop pedal, something like the Keeley effects loop pedal. The problem pedal would be ON all the time, and you would switch it in or out of your signal path by switching the FX loop pedal on and off - when it's off your signal would remain "true" bypass, and when on, the effect pedal would be engaged. Something like that might help with your wah issue. Here is a link: (it's showing as $99 on the Keeley website, but Sweetwater, and various online vendors have them for $85. I bought one of these for use with a Memory Man delay pedal; haven't had a chance to try it out yet, but I think that it will help *alot* with a non-true bypass pedal situation.

"Connect any effect to this unit that is "old school" and not true-bypass. In particular Vintage wahs, echoes, phasers, fuzz face type pedals, or even new effects that might have a weak bypass system. These elderly effects rob tone when they are off. Now you can make them truly bypassed when off with this little box."

thanks , yes, the wha comes first in chain, I dont know if it is true by pass ,but the problem is not my unit, cause I had another unity, pod hd 500 and had the same problem and not just with the wha, any pedal that  put on fx loop cause noise , i tried before my ocd and my suhr riot, and I have the same problem.And I dont use noise gate ona cleans patchs
