After my last board build I noticed I was getting a lot more noise than I had before.
Granted, it is a long chain, but had not heard this prior (hiss).
After some very methodical testing, I found three pedals to be the culprits, and they were all culprits IN BYPASS mode.
Gamechanger Light (reverb) and Bigsby - I had not noticed the noise prior in either but man it is there, even in isolation (tuner and it in the chain). Annoying but workable. I emailed them but since they are mostly guitar pedals I suspect they can be noisy and those guys donât care.
Here is the really bad offender - Walrus Audio Lore - and here is the weird thingâŚ
Plug it in power everything up - noisey hiss. Engage pedal, loads of noise////disengage pedal, the âloads of noiseâ from when it was engaged stays! argh! In doing some research this is a complaint of many Walrus Audio pedals I guess.
I have emails into both to see that is what.
But shouldnât a bypass be just that?
Shoudnât it add nothing (nor take away for that matter)?
Is there some sort of noise gate pedal I could get to drop out this hiss?
no, all are powered from Pedal Power Plus 3 or X8.
Hiss is only from the pedals listed above, all other pedals (even in the long long chain) are noise free.
I am ok with some noise when you engage a pedal, but bypass----- no thanks.
PS - yes, any USB plugged in to any pedal seems to make for a noisy mess, learned that one a while ago. The USB cables are landed just off to the right of the board in case I want to program the ones that use USB.
This happens even with just one of these pedals in isolation, with the Peterson tuner before it. Tuner is in buffered monitor mode (always on). Also happens if each is the only pedal (without tuner).
My delay and reverb from Walrus produce some slight white noise (this is normal). Not sure with bypass since I use a loop switcher.
For some reason my reverb gave a terrible hiss too this weekend. Apparently I had too many pedals daisy chained. I just ordered a decent power adapter to fix this issue.
The weird thing is that the chain was completely fine before.
This could be because the Bigsby is never truly bypassed (sorry I was misleading here). Itâs an always on pedal. This one I just chalk up to being noisy.
Ugh. Well, unless you find yourself frequently wanting a pitch-shifting expression pedal, you can probably just lose that one. Cool looking pedal but Iâd kick it to the curb if it were adding noise.
Itâs the least offending of the three, just canât keep it in the chain all the time, which is fine. Iâm more concerned with the other two. The light pedal has been in my chain for a long time and fine, and I use it a lot.
The Lore I had big plans for, and itâs past return window. Hoping they can correct the issue.
@howard - here are the videos I just made to send to the manufacturers.
Note, hiss in âclean modeâ with just tuner sounds really loud, it isnât.
The iphone apparently has an inner talent to pick up high pitched noises very well, lol.
hey @John_E , sorry I havenât read the whole thread but two ideas comes to me :
one pedal can have some sort of bad design and it makes it prone to capture and enhance the ambiant noise. not a good choice.
you could have a ground loop in your power supply. itâs very possibly this. in my experience, this kind of problem is often a ground loop. (but not always)
Same happens when powered on a One-Spot by itself.
So unless the ground loop is in the house outlet and not effecting anything elseâŚâŚI am still going to lean towards a faulty bypass circuit.
The Walrus Audio folks are agreeing with the theory, at least at this point.
On the Gamechanger Light pedal, this is pedal #2. When I got it in the very beginning they had a bad batch of pedals that wouldnât latch on / off on the bypass switch.
My hunch is that their âfixâ was duct tape and not solving the real issue.
