morgano Posted October 7, 2013 Share Posted October 7, 2013 Has anyone who owns a Zoom MS60-B noticed any background noise using it? I don't mean the usual white noise (hiss) that you get with all effects to some degree ( usually dependent on the amount of gain etc.). This instead is a continuous high pitched whine - I've measured it at about 5.5kHz. It's present all the time, it seems, the level varying depending on the FX selected. It's there even when my unit is running on batteries. It's there in various rooms (i.e. at home, at rehearsal etc), and it's there even with a just shorted jack plug in the input (to eliminate noise pickup from the bass). I'm wondering if I have a faulty unit, or whether this is just due to the budget nature of the device, and I'm expecting too much? BTW, you would need to have a bass cab with a tweeter to hear it, or feed it directly into a P.A. system or PC. Here a link to a short sound clip (again, it's not the hiss, but the high-pitched whine I am referring to): [url="https://dl.dropboxusercontent.com/u/1313046/Music/Zoom%20MS60-B%20high-pitched%20whine.wav"]https://dl.dropboxusercontent.com/u/1313046/Music/Zoom%20MS60-B%20high-pitched%20whine.wav[/url] Quote Link to comment Share on other sites More sharing options...
Jellyfish Posted October 7, 2013 Share Posted October 7, 2013 Sounds like a faulty unit, to me at least. I've just sold mine, but it was completely silent when running on batteries and from mains power. Quote Link to comment Share on other sites More sharing options...
funkle Posted October 20, 2013 Share Posted October 20, 2013 I've definitely noticed it, but only when using the amp sims, and even then you have to have the gain turned up high and the cab mix high too. Once I was able to reduce the gain, it got better, even when I mixed cab simulation back into the amp sim. This may be a fault in my unit...I may replace it with another one for comparison.

ratman Posted October 21, 2013 Share Posted October 21, 2013 I just recieved mine today. I spent a couple of hours playing it so far and I've had no noise/whining issues. I'd get yours replaced ASAP. Quote Link to comment Share on other sites More sharing options...

ratman Posted October 22, 2013 Share Posted October 22, 2013 Best of luck getting that sorted. Quote Link to comment Share on other sites More sharing options...
rainbowreality Posted October 29, 2013 Share Posted October 29, 2013 (edited) I think I may have a similar problem with a zoom b3. Silly question but what is a shorted Jack? I'd like to eliminate the guitar out of the problem! Edited October 29, 2013 by rainbowreality Quote Link to comment Share on other sites More sharing options...
dannybuoy Posted November 3, 2013 Share Posted November 3, 2013 I've had a B2 and B3, and both buzzed when being used in a daisy chain shared with other pedals, but fine when on their own isolated power supply. If yours is noisy with the bundled power supply and it's not daisy chained to other pedals then perhaps something is up, do you have another 9v supply you can try?

funkle Posted November 12, 2013 Share Posted November 12, 2013 Sorted my noise problem - turns out using the Zoom power supply as opposed to 2 other generic ones (both of which are meant to supply more power) was helpful. Quote Link to comment Share on other sites More sharing options...
