My pedal chain is to noisy and am looking at a noise canceler/suppressor To reduce the hum and his. I don't know what to go with on this because i don't know how it will effect the decay of my reverb pedal. The big problem here is my EH holy stain pedal. It runs a bit noisy Even set to clean. i think this is because the clean setting goes through the Distortion channel. Original it has to much breakup on clean but got rid of that by turning the pickup volume down and turning the amp volume up.
Any suggestions on getting rid of the noise?

It's kind of a hiss the holy stain pedal gives off even when in bypass since its not a true bypass. The different effects on the pedal will add to it. It even cuts in and out with the tremolo and reverb and all that is added to it.
I believe its from the distortion circuit apparently the clean channel still goes through the distortion circuit. I have to turn the volume on the guitar way down to get a somewhat clean signal through the thing. I like this pedal a lot and this is the only problem. With The guitar volume up i get a lot of breakup on the low E And since this rig already has a lot a bass to it it just makes an annoying distorted rumble sound wile the rest of the strings stay relatively fine. This is with all the bass turned down and treble up. This would normally sound fine in fact the whole things minus the holy stain is completely silent wile on.

Hmmm, then it's not something that can be cured without opening it.
I'd try a noise gate on that one.
Cheers!

Well i wonder if theres anything i can do to the board to clean up the sound get rid of the buzz and maybe even clean up the effects themselves maybe a cleaner preamp.
I love those stain boxes.... I nearly impulsively ordered one off ebay after watching an online demo...
I suspect as with most pedals, looking at the pcb you will find no bypass caps at the IC power pins... a sure start down the road of noise

I do really love this pedal. I needed a reverb for my little black heart amp so i went with this. It's a bit cheaper then the holy grail and i needed the tremolo. I actualy like it more then my fender super 210s spring reverb cause you can mix the signal a lot more. The tremolo is nice but nothing beats a Leslie. The pitch shift i haven't messed with enough to really say much about. The distortion settings are crap to me cause you cant adjust them and they run alot louder then the clean. You can adjust them somewhat with the guitars volume the same way i do to get rid of the breakup on clean but its just annoying having to do so much adjusting trying to find just the right volume for each setting turning the guitar down and amp up and vise versa to keep the output the same. I actually use one of those danelectro FAB overdrives and like it just fine. Actulay being only $15 I used one as a cheap mute pedal for awhile. i found without the adapter or battery switching it on just mutted the signal And i just put the tuner right before it in my chain. Any idea where i can start to fix this noise problem without to much hacking or endangering the pedal? Or a noise gate that wont hurt the tail of the reverb?
Maybe you can unscrew the lid from the case and post a nice photo so we can see if anything obvious can be optimised..
It take a look the bottom comes out and I'm not sure what you can see on the back of the board. I will hafta try to get the rest out these things are put together nice and solid almost like someone doesn't want me to take it apart. 🙄
This is the back open as well as a pic of the front.
An externally hosted image should be here but it was not working when we last tested it.

U3 appears to be a linear regulator,AFAICT. So it's not likely to be switching noise from an SMPS PSU. Some extra bypassing there can't hurt though.
U1 appears to have an X-tal on it, X1. There may be some digital hash making it's way around the circuitry. Extra bypassing,etc around U1 probably wouldn't hurt either.
The bypass is noisy? Hmm. Look into the grounding layout,and how it bypasses the signal. It looks like it's that multi-pole switch that handles the bypassing.. Is the signal path short,or does it wander all over the PCB? Perhaps using a piece of coaxial cable for the bypass,instead of the traces on the board,might help get rid of some noise. Atleast the coax is shielded from all the digital noise,etc.

do you mean bypass those components?
The distortion settings are kinda useless to me since i use separate pedals for that and you cant really adjust these. And since the clean setting still goes through the distortion circuit would it be possible to bypass the distortion circuit completely?

not absolutely sure, but i think the chip U1 is your delay/reverb chip. U2 seems to have something to do with U1, possibly a quad op amp, and U5 is likely to be a dual op amp. looks like the whole box is lacking a power filter cap,like about 1000 or 2200uf at 25V across the input side of u3.
