Digitech Vocalist LIve 3 Problem: My mic signal is lost when I toggle from the harmony switch back to the clean channel/ effect channel. I have had this problem on two different units....any solutions? Similar problems?

It's possible that the Harmony foot switch has become damaged or faulty. One thing you could try is to unplug the pedal from power, disconnect the footswitch from the unit, and then reconnect it to see if that resolves the issue. If that doesn't work, it could be a more serious issue that requires repair or replacement of the footswitch. You may want to try contacting Digitech customer support to see if they have any troubleshooting suggestions or if they can provide guidance on where to find a service agent in your area.

Yes it is so is every other effect you will have to plug the reciever of your wireless mic system in to the vocalist and the out of the vocalist to your mixer or amp

The buttons are probably scanned as a matrix and possibly a circuit board has been cracked causing wrong data to go to the microprocessor in it. It is unlikely this will be a DIY fix so you should contact Digitech for a repair facility.

You need to check the actual signal levels to make sure they are within the specs for the unit. The mic input is low impedance. Your mic should be like a Shure SM58 or equivalent. The output is fairly high... up to +14DB which will require you to turn down the trims on a mixer this runs into or set a -20Db pad at the input. I suspect your distortion is from the device output to the mixer input. It is VERY important that the mic does NOT "hear" the speakers as the feedback loop resulting will be mass distortion. The guitar should also not "hear" the mains.

Yeah I have an idea... It is likely static electric discharge. At this time of the year we get zapped touching metal things and it also drives electronics nuts... You don't even have to feel it to get zapped.

Try using in your bare feet and see if it fusses... We had a lady vocalist wearing those ugg boots and caused static pops in her microphone... anyway try the test and if it fixes the problem, then look up Staticide spray... You can get it at Amazon.com for example... spray floor in the area you are playing on to kill the static.

The only other thing is to check if wiggling the power input plug causes the problem. Those plugs are notorious for poor connections when they wear.

To the guy with the vocalist live 3. You need to change the FS (footswitch) setting under setup. It toggles between a true switch and working only when you hold it down.

Enter the setup menu by pressing both the up/dn arrows. In the setup menu you can change the switch mode from momentary back to toggle.

It sounds like the guitar level input to the unit is too low.

NOTE: With this product you MUST use an amplified or electric guitar that has a preamp within it.

If you have a straight guitar that does not have an amp in it, buy a preamp to first run the guitar through.

You need a directional microphone, and then it needs to be pointed away from the guitar. Another technique would be to provide some acoustic insulation between the mic and the guitar, like a wall or a partition like what is used to set up office cubicles.
