Line 6 Variax 700 6 String Modeling Guitar with Tremolo 99 280 0105 - Answered Questions & Fixed issues

I don't have a Variax but it sounds like an IC (integrated circuit) inside the guitar is getting hot and until it cools down, it does not function properly. Try the Line 6 website to find the nearest repair center. Good Luck!

If your strings are old try replacing them, or cleaning them. You can clean them by boiling them or soaking them in denatured alchahol.

Check your battery. A weak battery will recover a bit when you power down for a brief period. Strumming hard will overcome the weak amplification when battery is down. Check that your battery is at LEAST 8 volts.

Also verify your plug into the guitar is clean. The barrel of the plug shorts to the ring contact to connect the internal battery. Do NOT use a balanced TRS cable for your intrument as this will lead to a marginal condition.

The variax models the sound of the pickups or microphone sound of various instruments. You should be able to hear the sound changing as you rotate the model knob. To get the best out of it you should try it with a line 6 floor unit which matches the pickup sounds with the right amp sounds. I think it could be quite subtle, but have a listen to the acoustic guitar sound then compare with the strat sound and the banjo sound and you should be able to hear the difference. I would love to have one of these guitars by the way!!! I have worked in the studio with a Danish pro guitarist who now only takes this on a session.

The frequency of the A string when in tune is 110Hz.

What you are hearing is actually 120Hz which is the second harmonic of the 60Hz power frequency. It would be hard for you to distinguish between 110 an 120.

Try this test: Bring something that produces a reasonable magnetic field such as a wall wart power adapter that is powered near your pickup... Then you will be able to see that you are picking up stray magnetic fields from your environment.

Humbucker pickups attempt to quash such pickup by winding the pickup so stray magnetic fields cancel in adjacent coils.

Some pickup CAN occur on your cord and also in an amp.

If you leave your cable unplugged from teh guitar you are LIKELY to pick up some of this hum... The second harmonic pickup is COMMON when devces like full wave rectifiers are driven by transformers in the area.

The hissing is caused by a bad connection, most likely at the cable jack. Try replacing it and while you're doing that check the rest of the components - especially the potentiometers, used ones generate a lot of static.

You should be able to get one at any good electronics parts store. Take the old one with you and they can sell you the exact match. Make sure you take note of the wiring connections when you unsolder the old one. Take pictures if you have a digital camera.

Your answer looks like it can be found here:http://line6.com/community/community/support/instruments/variax Hope this helps. There are similar problems to yours listed and also factory reset procedures under Variax Troubleshooting Tips.

Go to the Line 6 website <line6.com> and go to support, downloads. The manual is available in pdf format there.

Make sure the volume and master volume are turned up. Try the amp with a different cabinet and a known good speaker cable. If you get sound, it's your speakers or your speaker cable. If still no sound, you need your amp serviced.

First of all, it is never a good idea to post your full address online. At most, your Zip Code should be more than enough information for people to help find things like a service center.But, to answer your question, according to line6.com/service_centers, the closest shop to you is:Field Services4215 North 16th Street Building BPhoenix Arizona, 85016

Someone posted that removing the white plastic cover on the board-mounted momentary switches exposes the contacts for cleaning; I chose to drill a 1mm hole with a pin vise, as the cover is held by melted plastic tabs, then spray some DeOxit solution into the hole. It has worked for each switch I've tried on my 2 FB's (just found one in the trash today, w/the same prob). Good luck!

Protective circuits kicking in. You may be overdriving the preamp to a clipping condition the amp sees as a problem. If it is under warranty, contact Line 6 and see if this is normal for this amp. It should not be, but you never can be sure.

Thes switches are LIKELY "switched dry" meaning they have very little current to burn off oxidation. The usual cure is to use gold plated contacts, but they usually don't due to cost.

You have two choices: replace the switch or if you can get to the switch, try getting some CRC226 into the guts of it. You can get the CRC226 at Home Depot in the electrical department. Blue can about $2.70. Make sure to only use this product as there are other CRC products there.

You have analyzed the problem... with the strings muted, the unit is quiet... that means the problem is with the guitar or cable picking up the noise. Move the guitar around near other things to search out the source which is probably magnetic fields... orient the guitar differently to sniff for the source. OFTEN lamp dimmers generate higher frequency components that can couple into the guitar pickups. The problem is fairly common.

You likely are in an area that has magnetic fields. Also you may have the settings on the amp that accentuates the noise. Eliminating this noise, especially at low levels, can be difficult if you have devices like flourescent lights that have magnetic ballasts.

You might also try running a different source into the amp such as a walkman player to verify the audio can be cleanly amplified. If that works, then the amp is OK.

Hi, befarms. The line 6 FBV Express allows you to select the A B C D in the existing/current bank. You will not be able to change the current bank, disable or enable the effects.
What you can do is, save the preset on the bank number that you desire by holding down the channel button on your amp whether it is A B C or D. Then when the button flashes, you can reinsert or rename the preset and save it to the channel(or bank) that you wish for by scrolling to the bank number and pushing the button on the amp (A B Cor D).
Therefore, you will be able to save your personal setting to a specific bank and channel.

Hope it helps you.

Sounds like it is overheating and protection circuit cuts it out.

Try putting a fan on it or driving it less hard.

Is it still under warranty?

If so take it to your local Line 6 service center. http://line6.com/service_centers/

Before doing any of this you may want to try another Line 6 amp. Could be a problem with the amp itself.
