If the third prong is the round one, then that is the ground to your amp. It will still work, however, the amplifier will not be properly grounded. So in a pinch you can use it, but you need to get the cable replaced. The ground wire is there for your safety, in case you plug your amp into a mis-wired outlet or if you are plugging in another instrument like a keyboard, mixer etc. that may be mis-wired. This could lead to a bad shock or worse. You have been warned.
The pot is generating noise. Some noise is unavoidable from pots. Using excess gain in the amp that that follows it will worsen the problem. If ypu can get to the pot and it has a way to squirt some CRC226 in it would help. You would have to use the spout on the can to squirt into the slot where the leads go into the pot. You can get CRC226 at Home Depot in the electrical dept.
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.
When you are changing the DSP effect on the fly, static or noise is NORMAL !!! The DSP is changing the data and having to recalculate on the fly and doesn't mute itself while doing so which results in "garbage sounds out".
The bypass setting should NOT get any tone UNLESS you have feedback going on. If your guitar can "hear" the speakers in the amp, the strings can vibrate and get feedback going.
Unplug the guitar and see if high freq tone is still there on bypass. If the tone is in the musical range, then there is a problem if nothing is plugged in. If it is a VERY weak, very high frequency tone, this may be the digitizing noise from the DSP. On bypass, the audio is likely to still go through the DSP, just not be modified by it.
Assuming that the amplifier is functioning properly, I suspect that the problem is either in the cord, the plug socket on the bass, or the volume control potentiometer. First, I would try another cord that is known to be in good condition (ALWAYS plug the cord into the instrument FIRST). Second, carefully remove the cord receptacle plug from the bass and examine the solder joints (check for loose wires). Third, carefully remove the plate that holds the volume and tone pots. Examine these controls for loose wires or faulty solder joints. CAUTION: If solder joints are found to be the culprit, care must be taken to correct this problem. If too much heat enters the pot, it can be ruined!
First off how long have you owned the unit? Bose has pretty good manufacturer warranties. Usually several years up to 5 or 10 sometimes. Once I have more information I will assist you further. It sounds like either the amp or something else may be defective inside the unit. Thanks, Lee
try a corded phone and unplug your cordless. see if that helps. If not go outside to your power meter and near it you should see a box labeled telephone. open it and you "should" see a spot to plug in a corded phone. you first have to unplug the little cord thats already in it then plug in you phone. If no static, then prob is in your house wiring or in a defective old jack or possibly another device plugged into your phone line (computer, answering machine, caller ID box, etc. ) .
If you do have static while outside & plugged into the "test jack" , then prob is in the phone companies regulated facilities and they will come out and fix no charge to you.
This is a very common problem that I have repaired for many friends. Sometimes the guitar jack becomes loose and gets rotated to the point where the wire breaks and/or touches the cord plug when it's inserted into the jack. You need to remove the access plate/panel at the back of the guitar body and see if the wire is broke or twisted. You may only have to loosen the jack retaining nut and rotate the jack to get the twist out or you may have to remove the jack and resolder the wire back in place. If its broke make sure to solder back on the proper terminal--the one with solder already on it and not the one that the cord plug touches when its inserted. Retighten the jack nut by firmly holding the jack from access side so it doesn't rotate again and cause that undesirable STATIC sound. Hope this helps.
