HT-40 : Another weird noise

[Vhalara]

Hey guys !

I did nothing special with my HT-40, but somehow since yesterday I got that weird noise : http://picosong.com/8Ccm/
Do you know where's the problem coming from ? Is it from the amp, or my guitar mics are f*cked up ?
It's not doing it everytime but it freaking annoying.

Thanks !

It sounds like you have a bad ground someplace. First thing would be to try another guitar.

I don't have another electric guitar... Can try with my electro-classic though. What does ground problem means ? If it's a problem is it coming from the amp, or maybe cause it's plugged in a multi-socket?

By ground problem, I mean multiple paths to ground. When you have multiple paths to ground, it can form a loop that picks up stray current from induction and causes noise.

Typically, the problem is usually the wiring in the guitar. The fact is that guitar builders are not electricians. So you can spend $4000 on a guitar that is very well thought out, made of great materials and meticulously assembled....but it might as well have been wired by a mentally impaired chimp who's blind in one eye.

There could also be something microphonic...whether it's a pickup or a tube is unknown. The only way to narrow it down is to try another guitar...

I can't try another guitar now, but I figured out something interesting today, might help.

It also does it when the amp is on, and the jack isn't plugged in completely.
And I SWEAR the noise wasn't here before.

It's me again, sorry !
It doesn't do it when I plug just the jack, but it does when I plug the jack and the guitar. I'm still gonna try whenever I can with another guitar but it might be coming from it, the thing is that it really wasn't doing it at all before...

Annnnnd sorry for the triple post. Tried it with my electro-acoustic guitar and the sound is clean as possible, no bizarre sound. So it must come from my guitar I guess.

Just would like to have an update from you guys, is it still possible that it's coming from the amp and not from the guitar ? Like I said I tried with my electro-acoustic so it's not an electric guitar...

If it's only happening with the one guitar, it's most likely that guitar.
