I wonder if any of you guys have come across this same problem. I run a low z cable out of the amp, into a Peavey mixer. For two gigs in a row, a couple hours into the gig, there will be a fairly loud static like sound. Something like a neon light would do. Then it will quit. I played last night and we changed the cable because we did find a problem with it. It was fine up until the 3rd set and I could here the static again but was very faint and short lived. I played the amp for about four hours the previous day and had no problem with it, however, I was not plugged into a board. The next gig I'm going to mike it all night and see what happens. I still think it's between the mixer and amp that's causing this noise. Supposedly, this cable is ok that we changed but I think we'll put a new one on and try that also. Any input would be great. Thanks, Loren. |

Loren,
One thing to consider since everything seems to be working, are there cell phones in close proximity? I have a BlackBerry internet phone and I have to shut it off when I play. If it is close to an amp all heck can break loose in short static-y interuptions like you are describing. At first I thought it would only affect older, unshielded gear and clock radios, computers, etc. but my new Roland BluesCube "barked" at me last night when I forgot to shut the phone off...arrggghhh. Progress huh?
Anyways, consider it as another possibility. Maybe the band leader can instruct all patrons to turn of all electronic devices and cell phones while the band is in motion..heh, heh.

| I had the same problem, a guy sitting close to me in the crowd had a cell phone , it was on vibrate so I could not hear it ring, it was driving my amp crazy, which in turn drove me and the rest of the band crazy, the only time it made that sound was when it would ring, I spent all night changing cords and jacking with that amp, after the gig I turned on my phone and it rang while I was messing with my amp and presto!!! I found what was happening!!! Hope that is your problem. |

I hope I'm not hijacking the thread Loren but it does seem to affect us all. I probably should have mentioned it earlier when I got my new phone (BlackBerry). I have not found a rhyme or reason as to what and when this static-y buzz occurs but I will share what is usually affected and what isn't;
The phone doesn't need to be ringing but it does seem to happen while the phone is updating e-mail and messages. It will do it if I am near my speaker phone at work while talking on the cell phonr as well.
While within 3' of my clock radio, work HP computer (but not home HP), Marlborro practice amp, home intertainment center, Roland BluesCube (but not Fender 65 DSP), and work speaker-phone the interuption happens and CP monitors "jump". I'm not an electrician but my first thought is that the signal is affecting certain speaker installations.
I didn't notice this with my standard cell phone. The people that I work with that have the internet phones all report the same thing. May want to also keep and eye on soundmen and their groupies as well since all the equipment is connected.
I'm doing a solo gig at an internet cafe/coffee house on the 16th of September...could be fun...
