awesome setup, which is the light blue boss pedal?
and is that an Ibanez Tube screamer i see?
as for hum....
As far as I know, you are likely to get a hum if you are feeding different electrical appliances off the same source (example running a fridge or a MAC 250 light and your pedal board , from 1 power source)
Interference could be caused by magnetic noise perhaps , dunno
Isolate your power supply , even if you have to goto extreme lengths...
there is nothing worste than a hum/buzz on a smoooth overdrive tone
kayDUB
Its a super chorus (CH1), and a maxon SD9, not tubescreamer (its more of a nasty lime green/yellow than the TS9)
Yeah, I'm not sure... I can't understand why there is no hum at home tho. I'm at a bit of a loss and not really sure how to find out what the problem is! ???
Maybe I should run the board's power off the same outlet as the fridge tonight and see if I get a hum (alltho thats prob not guarenteed ?) ... then i'll know it's a ground issue... could be interesting... ? and possibly a waste of time, we'll see!
Any suggestions on isolating my power supply?

I get a fair amount of hum at my place. Apparently the electric fencing tends to be the cause of a lot of problems. I got hum when I used my Ashdown Amp at church once. We put it down to a grounding problem. I'm no electronics expert, but a friend of mine suggested running a small UPS to supply clean, consistent power to amps and effects.

I found out that my boss OD-1's output jack was loose and when the jack was plugged in it would knock a wire around, so I tightened the jack and re-arranged the wire. The hum on my board is not as bad now as it was, but it is still there.
JoeyBones
So have you painted the board or are you sticking with the wood finish ?
kayDUB
Definately gonna paint it, but must just put some time aside to get the paint and actually do it!

Regarding the hum away from home:
If you're using extention cords check their earth wires, some only have live and neutral, and others may have been "repaired" by someone at some point.

Ouch!

I actually rewired the extension cable, but i use the same cable at home aswell... ☹
Thanks Kevin... good to see another Kevin around! represent!

Hmm, Kaydub I was hoping its was borrowed leads....
Maybe its the earthing in the wall sockets at these venues then....
JoeyBones
Have you built / bought a case for your board?
kayDUB
Nope, although I was thinking I should soon since the cape winter is around the corner....
I'll prob just build a lid type thing which will latch on.

Probably true! So I'm not the only anal-retentive type who carries a mains tester to gigs and complains to the management if there's a problem? ?

A mains tester ... Never thought of doing that.

Cheap and could save your life one day. A faulty earth can be lethal. I've used one since getting a shock from a mic at a venue years ago.

I've read stories of guys getting electricuted pretty bad. One guy got electricuted due to faulty circuitry in his amp. Beware of old or repaired amps.

So where do you get these tester goodies and how do you test them?
By the way, who's up for a section of articles relating to Gigging, buying gear, etc. All volunteered by our very own members, but organised categorically and all.
Show of hands?

Any electrical or lighting shop should have them. Many decent hardware stores too. You can get inexpensive ones which are just like a plug with a couple of lights. When you plug them in, the lights tell you if everything is OK. Something like this:

You get more pro ones too that can tell you more, but that's more for the electricians who have to track down the problems and fix them. You also get the screwdriver types - but they don't tell you enough, they are basically to check that a line is switched off before you work on it.

Groovy, thanks Alan ?
