Question about Line 6 Spider Iii 30

My spider III amp has no sound.. lights on but no sound

I have changed all cables and still not a sound. The amp was working one day.. then I plugged into the large headphone/record out jack on the right side by accident with my guitar and then turned on the amp. I dont think that has anything to do with my problem.. but thats what happened. I then plugged into the guitar jack and no sound. I have the Spider III Amp 30amp. Will a fuse do this?

First, do a reset on the amp by turning it off, then hold down the A (or clean) button as you turn on the power and hold the button for 5-8 seconds then release. If that doesn't fix it, I'd suspect the headphone jack itself. If it's rarely used, dust and crud can develop on the contacts over time and when you plugged into it the residue may have fallen into the shorting contacts and is now not allowing them to go back to their original position to route the signal back to the power amp/speaker. Try spraying the inside of the jack with a good electronic cleaner (don't go hog wild with it) then insert a plug into the jack a nuber of times. If that doesn't fix it, take it to the shop for a replacement.

No, probably NOT a fuse issue here (still lights up, etc.). Are you using the foot-pedal accessory? If so, then unplug it and go direct into amp. Try some headphone via the output jack (sound?) Yes -> GOOD. NO? -> Not so good. May require servicing. Also, check the guitar cord you're using. While unlikely, somehow it might have gotten damaged. Good luck!

SOURCE: my spider III 15 watt buzzes whenever i have a cable plugged in.

MAKE sure you have it connected to a three wire circuit that has the ground. A lot of these style amps will buzz if they are left ungrounded.

Also search for sources of buzzing light light dimmers.

Further, power supply electrolytic filter caps are suspect.

SOURCE: Spider III amp stopped making sound

After making sure your guitar cable is OK (they often cause the problem) check the inout jack on the amp. They often get broken by yanking cable sideways.

SOURCE: my line 6 spider III 15 watt amp isnt working

While it could be true that you're having a problem with the guitar or cable as the previouse expert suggested, to say that it can't be anything else is false. It could be a jack problem...it would only be apparant when the jack is making contact with a cable. I do think you should test it with another guitar and another cable but if that is not solving the problem then I bet it's a problem with the input jack of the amo itself or even one of the ionternal components (this is a digital amp and there are MANY components and settings that can trigger a problem like this) If the problem is not solved with a new cable/guitar configuration then it's time to take it to the shop.

Test the amp by touching the tip of the cord you unplug from the guitar and preferably try it with a second cable as well. If at high gain you don't get a loud hum, best to take unit for service. If it hums, then check battery in your guitar. The battery in the guitar is enabled when a cable is plugged in and MANY forget to unplug the cable from the guitar and have a dead battery within a day and blame the amp. This applies to most guitars that have preamps in them... there are some that are "passive" that do not have a battery.

When i power up my line 6 spider 3 ( i think it has two 75 watt speakers) all the lights work but no sound at all no static or speaker sound even at full volume. cable checks out, but even with a bad cable...


A pilot light means almost nothing other than the power cord is plugged in and hot and the switch is on. In this case, other lights run from various DC supplies so the inout fuse is presumed to be good... NEVER replace a fuse without knowing what caused it to blow or you will usually do more damage within a unit. There are several power supplies and you will typiclly find +/-15 volts on the op amps and 3.3 volts on the processor logic. Unless something simple like the speaker cable falling off this will NOT be a DIY repair. I would look to see if this speaker cable might have fallen off and ALSO check if you get any sound using headphones.

Spider III makes a high pitch sound when I plug my cable into the input slot. It won't stop and it keeps echoing.


If your guitar is not connected and the cable alone causes the oscillation, I would certainly question the QUALITY of that cable.

Poorly sheilded cables can pick up ground loops.

If you short the contacts of the cable at the guitar end and that stops the oscillation, I would try a higher quality instrument cable. MAKE SURE the cable you are using is an INSTRUMENT cable and not a SPEAKER cable which I can guarantee would cause the problem.

The Line 6 amps are NOT noted for reliability so I would NOT let that oscillating conditipon persist for any length of time.

Do NOT use excessive gain at the front end,,, use higher master volume and less front end gain if you are having ground loops.

I have a spider III 15W amp that has worked for a year. plugged in last night and it's getting power but no sound. Not even a hum from the speaker. checked everything and it's definitely the amp....


Try disconnecting the speaker from the amp with the amp unplugged from your power. Never work on an amp when its plugged in unless you know how dangerous it is. Check for resistance across the speaker terminals with a volt ohm meter to see if you have a blown speaker. Thats the first thing to look for. You should here a hiss or a low hum when your amp is on and you plug a guitar cord into the input without the guitar. Check those two things first.
