Digitech gnx3 makes cracking noise and the clip indicator comes on when it does


Hi Chris,
This is a discontinued product for the work station. Digitech does have a firmware update on their website. Have you tried that? Other then that, usually a bad guitar cord, dirty input jack or faulty input jack caused the cracking sound. These units sit on the floor where dirt and dust collect. Try spraying the input jack with a good quality conduct cleaner. (Radio Shack?) Make sure your guitar jack is also clean and then "exercise" the input by plugging the cord in and out several times. I am assuming this may help since it is the most simple approach. Otherwise, it may be a component issue and that cannot be addressed via email.

External Speaker hookup problem. I hooked up 2 external speakers (8 ohm, 160 watt) into my Marshall AVT 50 amp (tag on back says 4 ohm minimum). Everything worked fine, then I shut it down and now (next...


If you are competent with electronics, open it up and check the fuse(s). Especially if no lights come on. If you get voltage, then check the jacks you plugged into- they may have dirty interrupt contacts. When you plug the jack in- it opens those contacts that otherwise are closed making the circuit to the cabinet's built in speaker. Contact cleaner should clean them up if that is the issue.

While it is possible there is a power supply issue, you can see that quick with a voltmeter, it is not likely you did much more than blow a fuse.- very possible if you unplugged speakers with the amp operating..

If you think you killed it- you usually still get distorted noise.

FRONTMAN LEAD CRACKLES


5 possible causes-
1) dirty controls- you can clean them up with a shot of LPS1 through the vent of the control or from the gap under the terminals and work the control back and forth.
2) dirty tube contacts, Wipe the tube pins with a product named "Rail Zip" from a hobby shop.
3) dirty jacks- Use the LPS1 on the jack and the plug and plug the jack in a few times to clear the contact points.
4) cold solder joint on any of those items- reflow solder with a dab of new and make sure the contact is fully flowed.
5-broken wire- at any of those places mentioned.

While there is a remote chance you are developing static electricity and it is discharging into the instrument and getting amplified, if the ground connections are sound- that should not happen.

If it continues to make noise- check the guitar itself for the same issues of dirty contacts, dirty controls, bad solder connections, and broken wires as described for the amp.

My Marshall Guitar amplifier Makes Noise From Dirty Nobs. How do I Take the amp apart and clean the nobs?


the "nobs" that have the noise is what we call a "dirty pot" Some can be cleaned others are to far gone to ever work well again. To clean a "dirty pot" you need to get into the internal area of the amplifier. Most amps have screws in the bottom that hold the unit into the wood frame. unplug everthing from the amp. turn the unit upside down and remove the retaining screws. that should allow the guts" of the unit to slide out. don't force anything. then you should be able to see the "pot" from the top. If you can you get electric contact cleaner (I use the NAPA brand) and the spray stick (red tube) that comes with the can of contact cleaner. In a safe area (no flame or heat) you spray the contact cleaner on the top and sides of the "pot" then work the knob back and forth all the w ay to each end of the allowable movement but never try to go beyond where the knob wants to stop. repeat this at least three times. take care not to let the contact cleaner drip onto anything as it could leave a stain. I usually try to use a lot of newspaper under the unit and be careful not to use any more spray than you need. You should feel the pot getting easy to move as it gets cleaner. Let everytthing dry off before you reinstall the amp into the outside frame. Move slowly and take your time. If it works it will save you a lot of repair cost as changing out the pots is not fun and could cost almost as much as the amp is worth

One of my keyboard black keys is playing louder than usual what can i do?


One of the two contacts of that key is dirty. This cause the key velocity to be read as maximum making it loud. The keyboard contacts are conductive rubber pills that press across circuit traces on a board under the keys. CLean the pills and the traces GENTLY with ONLY 99% isoprophyl alcohol and Q tips. Getting at the contacts requires a lot of careful disassembly of the keyboard to get at the contacts.

My westfield e4000 les paul when plugged into anything doesnt work unless its switched to my bridge pickup and turned to 8 volume or lower


chances are that the contacts in the pick up switch and or volume / tone controls have got dirty over time and are not making good contacts.
The 3 position toggle switches in most budget Les Paul copies are prone to failure - only making contact on one position as the springs get weaker - you could try unscrewing the back plate and examining what is happening in the switch.
Try rotating the volume and tone knobs vigourously to and fro - if this produces a crackling sound the contacts are dirty - further rotation will clean them a bit but a little squirt of switch cleaning spray will help too.
Other than that it could be dry solder joints anywhere on the back of the switches and knobs or poor contact inside the jack socket

Nord keys not making sound


This will have the weighted keys.

The contacts for the dead keys are dirty and have to be cleaned. This type keyboard is NOT DIY unless you are adept at electronics. The actual contacts are accessable after a lot of dis-assembly.
They are conductive rubber that is pressed against circuit traces on circuit board.

Use ONLY 99% isoprophyl alcohol and QTips to clean both the contact and the circuit traces they press against. Clean ALL the contacts when you have the unit open as others are sure to become inoperative as well.

I have a triton le keyboard. i have three keys that are not sounding when pressed


You probably need to clean the contacts underneath those keys that are not sounding, otherwise check the components (diodes, resistors, etc..?) that are connected to those contacts , also check the wires and/or the connector that goes from the contact plate to the main board, see if there are broken wires and resolder, check if the connector pins are dirty or badly soldered and clean/resolder if necessary.

if all of the above fails then It is not a bad thing to check other connectors too, also any ICs that are plugged into sockets as there may be some oxydation so cleaning the connectors and unplugging and reinstalling the ICs could help somewhat.

Hope you can fix it.

Sound only coming out opf left channel


Probably there are dirty contacts inside the assign switch, also it could be a bad solder contact on the switch or there around.

The switch can either be removed and cleaned or replaced.

Cleaning is a bit delicate procedure, but can actually be done, you need to take the switch apart, taking care not to damage any of the parts, then you need to clean the inner contacts and the contact making clamps with some fine sandpaper.

Be sure to put everything back together as it was otherwise the switch may not work properly or it may not work at all (be gentle with the contact making clamps, they can easily be damaged / squashed).

It could also be a problem with faders or preamps, but i would take a look at the switch first.
