A few things can cause it. Bad ground\bad power supply filter capacitor\bad low level op amp IC. You most likely have a bad power supply or trouble at your input jack. Good luck!

Hi, i just bought a gnx-3 guitar processor and it hums loudly.


Normal 0 false false false MicrosoftInternetExplorer4 /* Style Definitions */ table.MsoNormalTable {mso-style-name:"Table Normal"; mso-tstyle-rowband-size:0; mso-tstyle-colband-size:0; mso-style-noshow:yes; mso-style-parent:""; mso-padding-alt:0in 5.4pt 0in 5.4pt; mso-para-margin:0in; mso-para-margin-bottom:.0001pt; mso-pagination:widow-orphan; font-size:10.0pt; font-family:"Times New Roman"; mso-ansi-language:#0400; mso-fareast-language:#0400; mso-bidi-language:#0400;} Sounds like a bad cable or pickup. Set the volume to a level that you can tolerate. You may want to turn off the amp between each of these steps. Unplug the cable from the amp; if the hum does not go away you have problems with the amp. If it does then plug the cable into the amp and short the end that plugs into the instrument. If the hum goes away it is the pick system in the instrument, if not you have a bad cable.
Good Luck

Feedback issues during live band performances


This is clearly a microphone problem. You need to review your mics and use a suitable type. Ensure the speakers are not aimed at the mics too.

My amp wont turn on


I have heard this problem occurs often with the vypyr I have heard to try and turn it oun without your guitar cable plugged in and it should work fine. If not try wiggling the guitar cable out a little and and should turn on and try and get the update for it.

I turn on the amp and there is loud feedback but no sound from guitar. there is a red wire a white wire then a black wire connected to the two but is open on other end?


Hi

It very much sounds like you have a broken guitar lead if I understand what you are describing and there is no connection at the other end. Can you borrow a lead from someone elese to check to see if it is.

What sort of feedback do you get, is it like a humming sound?

I was playing guitar through my fender 85 amp and the volume suddenly cut out to almost nothing and I couldn't make it loud again?


The speaker could be blown. Try touching a 9volt battery to the terminals on the speaker. If the speaker makes a popping sound its not blown. The other culprit could be the input jack of the amp. If its soldered directly to the board. The retaining nut may have come loose and the jack wiggle around with the cord tension. resulting in a solder connection breaking at the board. But that usualy will give a ground hum or no sound at all. So im leaning towards a blown speaker. (providing its a solid state amp) If it's a tube amp. it could be that one or more of the power tubes are bad or have a vacuum leak and may need to be replaced. ( you have to replace all the power tubes at the same time and have the amp biased.

PEAVEY TRANSTUBE AUDITION 110. PLUG UNIT IN POWERS UP . SITS THERE AND HUMS LOUDLY. SPEAKER WORKS. plug guitar in can hear it faintly, push lead chanel button in , hum gets super loud. HUM IS IN PROPORTION...


There should be an 8 pin IC close to the input jack that will be marked 4558 or 4560. This is an Op-amp Ic that is the most likely cause of the problem. Replace that IC and report the results here.

A HUMMING Peavey Classic 30


I repaired a classic 50 recently and the problem was a bad solder connection on the main input jack. You may also want to have the tubes tested.

If the unit is over 20+ years have it recapped.

I do this stuff but Vermont might be to far.

I don't know why you'd set the Peavey to 2 ohm to drive 8 ohm speakers??? My other thought is... I wonder if the phase is correct. try reversing one of the speaker wires Left or right side.
