I seem to always get a static sound out of my Line 6 Spider Iii below 9 o'clock on the volume knob. Not only is it staticy, but the volume jumps all around and goes from whisper quite 1 second to house...


It sounds like you have a dirty pot (the volume control). Unfortunately the only way to clean the pot is to open the amp up and try to spray some Servisol Super 10 in through the small opening in the pot case.

WARNING: Tube amps contain lethal voltages even when unplugged! If you are not an experienced service engineer then take it to someone who is! It is a pretty common task in guitar amps so shouldn't cost too much.

A tube amp may take minute or two to warm up the vacuum tubes. Use CRC226 into the volume controls thru the little slot where the leads go into the pots. The pot may have been worn out and require replacement.

Hello, I own a hotrod deluxe. I take great care for it and never move it. Normally on the clean channel, the volume is regulated by the volume and the master. Today the amp sounded only half as loud as...


Do you turn on standby every time and wait for the tubes to heat up first? If you don't, it can severely damage the tubes.
But a common cause of this could be just old tubes. Like any other piece of technology, tubes get old. If you like to play your amp LOUD then they wear out a lot quicker. You have to replace tubes every now and then. Because I'm not there to check out your amp, I can't give you an exact answer but it sounds like that's the problem. This isn't always a bad thing. You can make the sound of your amp exponentially better with nicer, new tubes. Your amp has 12AX7 tubes. Very common tubes to use actually. I'm not sure what kind of music you play, I'm assuming mostly rock and blues. But here is a list of tubes and reviews on them.

This is how to replace a tube:

A note he doesn't make in the video is to dust out your amp. I use the compressed dust spray for the inside of computers.
So overall, stop turning up your amp to 11, make sure it's well ventilated and dust it out from time to time. Hope this helped.

How do I get the electronics out of the cabinet to clean the pots .Thanks Paul


DO NOT CLEAN the pots... Use CRC226 available at Home Depot nin the electrical dept in them. Use of contact cleaners destroys the resistance element and its lubrication. Typically there are screws to remove to release the chassis... AND often the handle screws are ALSO used to hold the chassis... sometimes these screws are hidden under caps at the ends opf the handle.

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

I doubt that you have checked the tubes... tube checker's are rarity now and you can't look at a tube and "tell it is alright". If you leave the footswitch out does it do the same thing?
The probllem could be many things...and you haven't mentioned how you tested the items you are exhonorating. A common problem is a noisy or broken INPUT jack. Musicians forget to loop the guitar cord through the handle and the cord gets moved and yanked sideways wearing the jack and often breaking internal parts. Yjos also goes for the cord to the footswitch as well. Cords and connectors/jacks are the common problems. Less common but frequent are damaged volume control pots due to damage when handling... including broken solder where these attach to the circuit boards.

Output jack


Have you tried another cable between amp and guitar? Usually the cable goes bad first. Have you tried another amp or possibly tried another guitar on your rig? If this still indicates that your guitar's Standard 1/4" TS Jack is noisy, remove the oval cover over the jack and check the solder joints for the wiring. Follow the wires back to the tone and volume pots and check those solder joints. If everything is secure...Plug in, power up and check for noise while turning the volume pots stop to stop. If the pots make a scratching noise, shut down rig and unplug the guitar. Get a can of spray contact cleaner with a small extension tube (available at electronic shops) to spray in the pots while turning them. (May have to remove pots fom the guitar to get at small openings on side of pot can.) Spray jack and test for noise. Jack STILL
noisy...If you can solder...unwire old jack, remove from guitar, take to electronic shop, match to Standard 1/4" TS Jack, install in guitar, resolder wire connections and test. If you cannot solder...take guitar to
a reputable shop or dealer that does this repair. Good Luck! P.S. The
spray contact cleaner can be used on the amp jack, pots and switches
too...just make sure the amp is unplugged from the power supply before
doing any spraying.

Dirty high switch on a Crate practice amp


NEVER use switch cleaner such as DeOxit on pots !!!!!

I have used CRC226 available at Home Depot electrical dept.

I SUSPECT that the resistance element in that pot is cracked. This is common if the knob sustained a hit. Replacing the pot is the only cure if the element is cracked.

Reviewing the schematic, ALL audio passes through the wiper on the HIGH tone pots. If the wiper is intermittent, so will be the sound.

If your unit is solid state amp, the pot looks like a 10K ohm LINEAR taper.
If you have a tube type, then the pot is a 250K ohm LINEAR.

Note that the other tone pots in the units are AUDIO tapers, but the high is a linear taper.

Get repair parts from either DigiKey.com or Mouser.com

No clean tone - no volume


First thing I'd check is if the valves / tubes are plugged in properly (it doesn't take much to loosen them) Unplug the amp then take out all of the valves and put them back in again.

If that doesn't work, try swapping the preamp valves (the little ones) around (let them cool down first) that'll tell you if one of them is worn.

Failing that I'd try cleaning the gain and volume pots with some switch cleaner, and if that didn't work I'd bite the bullet and buy a new set of valves.

Hope that helps

Electric Guitar wont play through Amp


the buzzing is indicative of an open ground connection, check the cord by substitution or with an ohm meter, if the cord is good look at the connections to the jack inside the amp ( im guessing you built the amp from a kit). Is this a solid state amplifier? Tube amps have lethal votages and should not be experimented on without knowledge of electronic safety. Also if there is more than one input to the amp try plugging the guitar into another one and see if its still the same.
