Will amp still work after third prong is broke

There is no other fix than to replace the volume pot. if you are not familar with working on electronics, it will require a trip to the repair shop. Unfortunately, the repair charges will most likely be more than the cost of just replaceing the amp.

I would never use a fender amp without the ground plug as I have been electrocuted by doing this and could not let go. I will be wireless from now on.

Incorrect connections or volume settings.

• In powering up, mixer first then amp

• In turning off , amp first then mixer


If hum still persist, without the mixer connected

then speaker amp may need servicing.

Greetings! Ok, your amp has an XLR (3-prong) Low-Impedance input on Channel 1 for a Mic. All the other inputs are 1/4" High Impedance inputs, which are for instruments and/or other High Impedance items including low quality High Impedance Microphones. The SM48S is a high quality Low Impedance microphone, so if you use it with a 1/4" plug, it will be in a High Impedance channel, and will be very LOW in volume in comparison with everything else. So, you must use an XLR (3 prong) cable from the Mic to the Channel 1 input on your amp. That will do the trick. Good Luck with your new amp and Mic!

Amazing guitar!

Unfortunately, I have not been able to find the specialized plug you need. Being 1 out of less than 400, it is doubtful that they are still being made. However; any decent music shop will be able to repair your old plug.

First and foremost make absolutely sure you know what you are doing. If the amp is in good working order you should be O.K. The biggest safety check you can do is make sure that no one has removed the ground prong from the power cord. If it doesn't have one then you should take the amp to your nearest qualified amp repairman who can do a certified repair on your amp. For instance if it is a Marshall product, take it to a Marshall dealer. This type of repairman not only has the training, tools and schematics to work on your amp he will also be able to tell if someone has done a safe mod to your amp. Not only that he can be held contractually responsible if you are injured through the correct use of the amp after he has done the repair. Read your service agreement carefully before allowing the work. Amplifiers can kill you.

You can buy new connector and replace broken one. You need skill at soldering and of course have to open the unit to access the broken connector.

I have a soloution that will work as long as you still have the metal shaft on it?
if it does go to your local electrical store and buy a new knob.
then all you have to do is screwthe knob back on to the amp.
please reply and tell me if that helps.

I'm pretty sure t6hat the output jack is a sealed unit(contacts inside soldered to the surface of the circuit board. You may be able to grasp the center shaft of the plug with a thin jawed hemostat or really skinny long nosed pliers and pull it out that way. Make sure the amp is off and unplugged from the wall. If that doesn't work you will either have to get it removed at a shop or disassemble the amp to remove the circuit board and unsolder the jack and replace it or get the broken plug out of the jack once it is unsoldered. I've never had a Line6 apart yet but thats probably the type of jack they used. Thats because it has to be electronically isolated from the chassis. Hope this helps.

You might have a ground problem. Does it do it in different outlets or when you take it to someone else's house? One easy solution to ground problems can be running a three prong to two prong adapter on the power cable. Give that a try and see if it helps.
