Guitar Amp trouble...... Gets power but either no sound or very little.
Hey, hope you can help me. I have a Torque guitar amplifier and the thing is just playing up and I can't afford to have it repaired so need to tackle the thing myself. It turns on as normal but just wont put out any sound. At best I get broken sound of such poor quality that it sounds more like a weak buzzing noise but that just comes at totally random intervals and then that sound will disappear. I have tried different leads so its not a lead problem and I dont think it is the actual speaker itself either as I have tried just plugging headphones into the amp only to get the exact same results.
So..... Gets power but wont produce any sound apart from random spurts of sound so bad in quality it sounds like a cheap kiddies keyboard that is running low on batteries (literally). Same result with or without headphones.
What can I do?
Your problem sounds very similar to mine. I have a Marshal that does the same thing. It gets power but either no sound comes out or it's fragmented and buzzing. I took the circuit board out and found that a fuse had pulled/been knocked loose and was hanging free. If you take your amp apart, make sure you unplug it first. You're going to be be looking for something that look likes a small lego that suspended above the circuit board by wires coming out of both ends. If ones of these wires has pulled free then that's your problem. You can temporarily fix it by pressing the wire back into the circuit board and placing electrical tape over the top of the fuse to hold it all in place. If you do this, however, you can't play loud or it will rattle loose again and you don't really get more than about 10 minutes of play time. I'm about to solder mine whenever the guns arrives, so I'll let you know if this is a DIY project or not.

Retired sound engineer here, so you're in luck. First, it depends what you're trying to do.
1. If you just want computer audio to come out of the Marshall, just get a 3.5mm male to 1/4" male cable.
2. Usually you wouldn't plug into the earphone output, but the audio line output on the back of your computer (usually green).
3. If you want the computer to create effects in real time on your guitar, instead of plugging the guitar directly into the Marshall, get a second 3.5mm to 1/4" cable and plug the guitar into the computer audio input (usually a blue jack in the back of your computer). Best of luck!
I am no expert about such things but the electric guitar pickups work with steel strings, wouldn't work if the strings weren't steel - the pickup is a coil of wire and the vibration of the steel string generates an output in the coil the amplifier can work with.
The pickups of the acoustic guitar are presumably glorified microphones that would usually work in a similar fashion to the above, by generating an output but if they are active devices they will need a power supply in order to generate an output, something a standard amplifier input will not provide.
An active device either needs an independent power supply to make the device work like a radio needs a battery or the device will create the output by varying the current flow of the voltage applied across it.
It sounds like you have NOT connected the power adapter to the box to power it. The guitar sound won't be too loud as you run the hose to your mouth and pick up the sound with a microphone such as a Shure SM57 which then goes to your amplifier. Without the power adapter the internal amplifier will not produce any output.
Hi Dan I wish I could just say what to fix, but you can not do this at home. Line 6 is a great amp and worth the time taking it down to the music shop , to be looked at an give you a repair estimate. good luck keep on rocking in the free world. DFD
Nine times out of ten, any problem with an amp having no sound coming out, it's a wiring issue. Make sure all of the wires internal to the amp are propely hooked up. Also, try switching out the quarter inch cord you are using from your guitar to your amp. Could be a bad cable. Unless you have blown the speaker completely, something is loose or not hooked up properly.
