Pedals can add a bit of noise.

Hum can be hard to avoid; mostly, we just deal with it.

More than likely it's nothing a noise gate can't fix.

I thought you had a hum bucker?

Noisegate brah!

He doesn't have any crystal lettuce tone noob, I would be willing to bet that it's the mojo that your hearing. Mojo does what it does, whether you like it or not.

I have an ISP Decimator but I just got a Boss NS-2 for $50 on ebay. Pick one up. I think the Decimator kills more noise but the NS-2 is cool for fx loops.

the mxr smart gate doesn't affect your tone at all. once you get it dialed in, you won't have any loss of tone or dynamic response.

I had a MXR Smart Gate and got rid of it. In some applications it was completely transparent but for the most part I felt tone suckage.


As others have said, tube amps have some hum to them. No denying that. Question is whether or not it is enough to bother you over time or get in the way of gigging/recording.

Lots of things can induce hum too....sometimes it is just a matter of finding out what it is.

One of the greatest amp testing methods known to man is turning off all other electrical devices around you, turn off the lights, and observe your amp

I don't really have any trouble with my ISP affecting tone or cutting off notes. Maybe it's just me. I run it in the FX loop.

^+1 to other devices inducing hum. TVs and computer moniters do it pretty bad sometimes. And I've even had situations where the location I was standing relative to the amp or the way the guitar was facing affected hum.

In my opinion hum is "OK" buzzing isn't.
If I get too close to electronics with my guitar my amp starts buzzing.

This.
Some of us mod our amps to reduce hum but there's always some. The thing to see is, "does the amp hum with nothing plugged into it?"
If not then the problem will most likely be the guitar and/or cable picking up hum from outside sources. If that's the case you have to look into modding the guitar and/or using better quality cables.

If the electronics you're by aren't on does that affect it? For example, if you're by a computer but it's in standby mode, will that affect it?

My Jet City has quite a bit of hum when the post is above 5 on the crunch channel. I think its just part of the amp as I can't alleviate it

EDIT: You were right Cath, I've had that longplate JJ in V2 for about 2 months now and it's already starting to crackle. Bumming, it sounded so good there too.

Lots of things cause hum. A bad pickup, bad grounding, electric devices in the room that are on, high gain on an amp....

It's pretty much normal. But like 311 said, it really just boils down to what you feel like dealing with. Some people don't like hum, others (like me) just deal with it.

Hell, I happen to like my 60-cycle hum in my Strat, thank you

Try cleaning the socket before you give up on it. They are a very nice sounding tube, I have a few of them kicking around here. I stocked up a bit when I knew my supplier had some old stock of them. Grabbed a few EL84's while I was at it.

Oh it'll drive me insane. Literally I think some dude invented humbuckers cause he heard insanity in the hum. They sound thick as shit too.

Televisions too. Turn it off please. If the amp is on, play the ****er or turn it on off thanks.
