No sound through the amp. Other guitars work fine . This happened right after I got it . Then it just started working right. Now no sound through amp again?

Have you checked a different cable?. Also, when you plug in the unit, there should be a "pop" if everything is turned on. If there isn't, the connection is bad someplace.

It sounds like you have a dead guitar cable or the preamp section of the amp is blown. It needs to go to the shop. It's way cheaper in the long run to just take an amp in. If you try poking around without knowing what you're doing you can fry something more expensive or worse yet yourself! There are leathal voltages in a guitar amp!

Sounds like a problem with the channel itself, if the clean channel works then its not the lead, input, guitar or the drivers. You have to be careful when opening up amps as some can hold a residual charge and there can be danger of electrocution.

I would recommend getting it looked at by a pro, it doesn't sound like an expensive fix.

First thing would be try another guitar with the amp. This will eliminate if it's a problem with the guitar or the amp itself. If the guitar is working properly then check all the tubes to be sure they are all seated into there slots completely. Depending on how much use they have been played it may be a good suggestion to then replace your tube's. Occationally the tubes will start loosing power, making sound fluctuate up and down or distortion sounding static in background noise. You will notice a big difference with newer tube. But remember the bias must be set correctly to match the new tubes so they won't over heat. You can check out youtube for setting the bias. Anyway this is my suggestion and I wish you good luck.

Since this is a brand new amp right out of the box, I would recommend returning it immediately to the dealer you bought it from. If it can't be repaired under warranty they might replace it with a new one.

First of all I suggest that you try your guitar through another amp you know works without the feedback. There is a very slim chance there is something wrong with your guitar but I would say no. You didn't mention what kind of amp you have: solid state, tube or hybrid. It would help if you tell us what brand and model number your amp is. Try setting your amps controls the way you usually have them and using a long cord that works properly, isolate your guitar by putting it in a room with the door closed by running the cord under the door. Is the feedback still there? Try playing with your back to the amplifier. Is the feedback still there? You need to identify the problem. Is it your guitar or is it the amp? Here is a link to tube amp troubleshooting:http://www.geofex.com/ampdbug/ampdebug.htm Here is a link to guitar feedback causes:http://www.guitarsite.com/discussion/messages/23765.shtml If you decide it is your guitar you can have a look for broken solder joints etc. There are wiring diagrams on the internet. If it is your amplifier, you should take it in to be serviced. Take it to a dealer that carries and services that brand. Unless you have all the tools, a schematic and electronic troubleshooting experience you are in danger of injuring or killing yourself or making the problem worse. Hope this helps.

The next time it stops, unplug the cable from the guitar and touch the tip of the connector with your finger. If the amp hums, then the amp is still working and the problem is in the guitar. If there is no hum from doing this, then the amp has am intermittent.

Try this before it fails to see what to expect in the way of the hum from this test.

Common problems with the amp are OFTEN with a broken input connector or bad switch on the preamp output jack if it has one.

There are MANY other things and without troubleshooting it is hard to steer you to a fix.

Hi,

It's not your pickups. It would be nearly impossible to loosen a wire inside of your guitar by having even heavier than your amp head drop on it. It is most likely your volume pot. The post, if hit hard enough, can virtually distroy your pots. Another possibility could be your jack, al though considering where it's located on your guitar, it would be very hard to damage it by having something drop onto it.

There is little else that could be the problem. Hopefully you didn't damage your guitar too badly. If the guitar was in front of me, it would be a relatively easy diagnosis.

Fortunately, volume and tone pots are inexpensive, and if you're handy with a soldering iron (or you have a friend that is) it is an easy install with four to six solder points, depending on your configuration. I don't want to assume it's a stock setup, but when you take off the rear electronics cover, you will immediately see what configuration you have.

If you have possibly damaged the pickup bobbins (assuming you have the stock humbuckers in your guitar), you would be able to see the damage, It would either look damaged,or work correctly. As you know bobbuns are simply wound wire, and that's not easy to damage. Plus your strings provide a minimal amount of protection, unless your amp head slammed it very hard. Start by replacing the volume pot. Cheapest parts first. There is no way to test the pot with anything like a potentiometer, because there is virtually no voltage that passes through the pot. Additionally, unless you have active pickups, your pickups cannot be either. If you do have to replace your electronics, you can find a large variety and even upgrade your parts by searching eBay. The good thing is that you havce a guitar, and guitar parts are abundant, relatively cheap, and most people change out electronics just to achieve a different sound.

If you are so inclined, most good guitar shops will diagnose your problem for cheap and apply the cost of the diagnosis to the cost of the repair. Good luck, and I hope I have given you some information to work with.

Thank you for using FixYa

there is an open connection, most likely right off the input jack ,causing this issue. Resolder it or retension the jack connection.
