Noisy Microtubes...?

[ole Jason]

How are you powering it? Have you tried to replicate the issue in a different building?

 

[Darkglass]

Yes, in my case it's still there when muting the input signal from the bass (with a TU-3 tuner for example).

That hum is very characteristic of power supply issues, but you seem to be using regulated ones so AC ripple shouldn't be an issue.
Was that test done with the effect by itself (i.e. nothing else in the chain nor power supply)? If so please write me to [email protected] so we can coordinate a check up.

in my apartement the electricity is really old school (building from the 1880's ... only god know when was the electricity was done) , and there's a GROUND problem.
with most effect i have no problems, but with my B3K/B7K i hear the same thing sometimes. I realised it was't the pedal because in other places when i plugged in (using a DC BRICK) i had no problems....

it doesn't bother me when i just practice, but for recording it's an issue... as i was already planning back then to make a smaller "can't leave the house without" nano pedestrian, i bought the pedestrian VOLTO... when i use it i have no noise

Yeah, I recommend 1spots as the most affordable option I know of, but of course we all know there are several better options out there!

As for the noise, it'd be good to see some clips, specially comparing it to the Myco on a similar drive setting (that would help determine whether the noise is within normal range or not).
Feel free to write me at doug (at) darkglass dot com. Thanks!

Hi Doug,

Clips sent to your email !

Thanks !

So fill the rest of us in. It sounds like a power issue. Have you tried the pedal elsewhere?

 

[Inertialsky]

Can anyone recommend a good small power supply that has an ON\OFF switch? Needs to be able to power my B7k and 4 other 9V pedals (5 total)

Call me lazy but I'm really sick of bending down and plugging in the one-spot every time I want to play.... I must be getting old

 

[jwr]

I must be crazy because I can't hear it?

 

[MoonQuake]

I'm gonna let Doug have a listen to the clips I sent him before reaching any conclusion.

I'll keep you guys posted as soon as things are sorted out.

Again, have you tried the pedal elsewhere? It sounds like a power supply issue. Very simple to test.

Yes, like mentioned before, I tested the pedal on my board plugged in my DC Brick and tested it appart with a Boss 9V adapter.

Same thing in both cases.

I also had the chance to test it at home, at rehearsal and on a gig and again, same thing in every location so not a matter of bad electrical either.

Would this be considered normal noise? Setting used were not too aggressive.




In this video the pedal was alone in the signal chain and had a dedicated power source. I replicated this setup in a different location with no success... until I changed the power source. I was only using dedicated power sources with input of 230V (I am in Europe) which seems this pedal does not take well (in this case a ZOOM AC ADAPTOR AD-0006E).

Soon as I tried a universal one (with a 110-230V input- in this case the old BOSS AC ADAPTOR PSA-230S)... puff! the hum was gone.


Bass_steak, I hope you'll find a solution to your problem also!


P.S. Did I mention that this pedal is awesome?

Thanks Doug for helping me sort my problem out, it was indeed a power supply issue. I hope you'll find a solution for bass_steak's problem also

Hi,
Do you have another od in the chain? I remember having issues when i stacked a vmt into my b7k.

Doug helped me understand what was going on !

Here's an update....

Doug listened to the clips and told me that the noise level is within normal range for what's considered extreme settings (level at 3 o'clock and max). Below noon, the pedal is dead silent.

So case closed as far as I'm concerned.
