Members fenderBOYroy Posted April 16, 2007 Members Share Posted April 16, 2007 Why does my Vox Wah pick up radio signals, when turned on?... and how do I fix it.? please help. Thanks. I REALLY just wanna sell it so I can get a Budda Bud Wah, but I'm not tryin't to get over on anybody and sell them a crap vox wah... Link to comment Share on other sites More sharing options...
Members hilikus8 Posted April 16, 2007 Members Share Posted April 16, 2007 It'd probably is a combination of your pickups, pedals, cables and amp alltogether than the pedal itself. Try plugging/unpluggin things gradually and see if the problem still appears. Link to comment Share on other sites More sharing options...

Members analogmike Posted April 16, 2007 Members Share Posted April 16, 2007 Radio Frequency Interference (RF IF) is a tough one, mostgain pedals like Fuzzes and even some wahs have a lot of RF problems.Since we cannot duplicate the problem here (it has no noise here)it's not something we can fix at our shop. Gain is amplifying the RF from the air like a radio, it is tunedto the local station. Sometimes shortening wires or adding ferrite beadswill help but since we dont have the problem here we would onlybe guessing. If you have a good tech he can try shortening the internalwires one by one and test to see if that helps, or he can try adding more and more ferrite beads and see if that stops the noise. Also you can try to add a small capacitor on the input of the boardor the input jack to ground, that often kills the noise. Try somethingsmall like 100pF then go bigger up to .01uF if needed. We oftenput a small cap right on the switch from the TO BOARD wire connection(gets connected to input jack when ON) to the GROUND connection. Also dirty jacks can cause RF interference, try cleaning themwith a swab and some contact cleaner. A customer wrote :"One thing I did was to uncoil all the power leads in the back of the rack. I had them coiled up pretty tight and then cable tied. This immediately helped, but I wasn't completely satisfied. At this point, I noticed that to make the radio signal be it's worst, touching the audio plugs on the back of the power amp (Metal sleeves) would do it. So next I soldered some 4.7pf capacitors across the DC connectors on my pedals. " another customer with RF problems with a sunface wrote: "Thanks for the note, Mike. After applying an, ahem, no-to-low-tech technique it seems that the RF IF problem is gone. Get this: after reading your reply I got to fiddling with the guitar cables in the chain, which includes a Framptone Amp Switcher in front of two amps. Anyway, I just swung the guitar-out cable from the Strat around from the front and behind my body and presto/change-o, the RF IF disappeared. No contact cleaner, no screwdriver, no solder. No BS." Hope that helps, good luck! Link to comment Share on other sites More sharing options...

I have another Wah and several pedals but only the Vox has this issue. At least it has the good taste to pick up the local AM station that runs SF Giants games, nothing like a hot wah solo over a Barry Bonds steroid induced home run.

Actually, it appears Mike pulled the exact text from his own site; hence, saving me the trouble of posting this useful info for you. I did this to my V847 and at first it didn't seem to help. However, I noticed that my input plug was lose-fitting in the wah jack (3 prong: tip, ring, sleeve). I would nudge it with my toe and the RF was intermitant. I think Vox could be cutting costs on jacks. What I did is replace it with a tight fitting one (good ground return) and this has solved my problem...along with the cap fix, of course. good luck Link to comment Share on other sites More sharing options...
