![]() The safety ground on your power supply (if it has one) doesn't count, since it doesn't connect to the signal ground. So unless you have a mains-powered pedal (with safety ground connected) and is powering it from a different outlet than the amp, there's nothing there to form a ground loop. Also, power conditioners might help, although the cheaper ones mainly only helps with spikes and surges - to get one that will effectively clean up really dirty power, you need to start looking at the pro range.Ī word on ground loops - they will only occur when there are more than one path to ground. Hunting round the venue with a really long (one or more 100 footers) extension lead can help find a power circuit that is less affected. Most often, those are caused by light dimmers dirtying up the power in that circuit. If the amp hums on its own, and it doesn't do that at other venues (ruling out any internal issues in the amp itself) you're definitely looking at a dirty power issue. Again, turning the guitar volume off will let you hear just the amp (and any noise generated in it). Next step is skipping the pedalboard - plugging the guitar straight to amp will let you know what (if any) noise is picked up or generated at the pedalboard. That will rule out any noise entering the signal via the guitar. Wild rider motorcycle parts, Intervalworld promotion code 2016, How to remove. First thing to try is simply turning the guitar volume off. Editor de videos sony vegas pro 11, Fatmagul part 35, Tmx finance linkedin. So finding the spot where the noise is generated is vital. Only thing that killed it was putting amp on standby, which was a pain. Couldn't spend too much time trying to isolate it. Kind of distracting during quite moments. It lessened, but didn't go away completely, when we tried different power sockets. But nothing is going to stop hum WHILE you're playing, because the noise gate has to open to let the music thru and the hum will sneak in with it!Ĭlick to expand.Like drbob1 said, a noise gate (or any other noise busting device placed in the signal chain) can only deal with noise in the signal chain. 1 Playing in church last night and had what seemed like 60 cycle hum. So would a volume pedal or tuner last in the chain-turn things off at that end and it's quiet in between songs. ![]() Lots of this stuff in church, unfortunately.Ī noise gate would help if the problem is guitar/cable/pedalboard. Poor quality patch cables and sound cables will also create a hum. Nasty interference in the room: lights, other powered equipment, computers and so on. Dirty power-power conditioners can help but something like the Ebtech Humbugger which is an isolation transformer for power to your amp, might help.Ħ. Amp-particularly poorly biased power tubes (they drift) or preamp tubes going microphonic, but dirty jacks or pots can contribute as can bad solder joints.ĥ. Pedalboard-power supply issues (especially if you're daisy chaining or using one without isolated taps), bad cable, dirty jack.Ĥ. Cables-they go bad, test a few different ones.ģ. Guitar problem-cold solder joint, pickup going bad, dirty jack or pots-try it in another place and see how it sounds.Ģ. Unfortunately that's a bugbear that's going to take some sorting out (I almost said a demon that's going to take some exorcising but maybe that wouldn't be funny?).
