bad Tremolo noise from Amp(?): answer inside

[crankyrayhanky]

hey

my rm100KH has a warbling sound on the high E string it is most apparent- sounds like a tremelo effect. I imagine I should just go ahead and replace all the tubes, but curious as to which one is the most likely culprit?

 

[crankyrayhanky]

Bueller?

I had bad trem noises. I ended up shoving a piece of old tshirt in it to help suppress it. With my short run with the Hush Ultra, the noise went away, but the Ultra did nothing for my lead channel which I use the XL for.

That's a really odd issue. Have you ruled out the setup on the guitar with another one? If so, try tube rolling with a new tube starting at V1 until you find the culprit.
Hope that helps and let me know how you make out.

IDK...To me it's a classic case of the amp desiring a tremelo effect....It's trying to make its own....Feed the MTS monster.....

Check the PIs too....

 

[crankyrayhanky]

I've tried a few axes, all recently setup by a pro, all have a strange tremolo

Same axe direct into my 11R>headphones, no issue (?)
I am a bit disturbed that this surprised JF, I hoped this was a typical effect of dying tubes...I'll keep you all everybody posted

This is a very strange problem. Are you able to record it? Can you email the recording to me a [email protected]?

 

[Jaded Faith]

It's might be something I have encountered before, but it would be easier to tell if it was in front of me or if you had a good audio clip of the issue.

Because you describe it as a tremolo effect, it makes me think it's impacting one side of the wave. Something like a bad PI of pair of power tubes (that's odd though, they rarely fail in pairs!) would be my first thought. Tube rolling starting at V1 would be the best starting point.

Does it happen on any/all channels at any volume? Nothing in the loop of course. Just guitar straight into the input. Is there a fan on in the room? Sounds silly but it happened to me once long ago....and it was the fan.

 

[kc2eeb]

Or, do you have an electronic air filter in the room?

 

[crankyrayhanky]

I did have a ceiling fan installed recently...lol, I'll have to do some testing and report back.....thanks for the support!

 

[crankyrayhanky]

A funny and happy ending:

:shock: :lol: :lol: :shock:
The ceiling fan was the culprit! Lol, now I'm hot!

Thanks Bruce and everyone else!

 

[bruce egnater]

That's really funny because I just made that up!! Kidding, it really did happen to me. Glad that was it.

haha...Had me for a moment....I thought perhaps there was a placebo effect on Ray considering the mighty source of the info.... :lol:

You do realize this was not an electrical phenomenon. It was simply the fan disrupting the air in the room which affected what you hear.

Yes, pretty wild, it had me going there for a few months wondering if it was guitar setup/tubes, etc
It's actually a pretty cool effect...the room is a medium sized 3rd bedroom, high ceilings, tile floor- sounds killer for vocals and acoustic guitar. A bit much for hi gain metal, so I put a small rug down.

The fan oscillation at different speed gives a tremelo effect...I love creating authentic real world effects in lieu of digital, this will be fun, now that I know what's going on!

This thread has been really cool. It went from possibly being an unknown electrical issue to being an acoustic one. Cool. Bruce knows his amps. Thanks Bruce!! What a class act!! 8) 8) 8)

This is 100% true. I have a killer floor fan that I place in front of me at practice. If it hits my pickups straight on the force of the air flow will cause some noise on a high gain channel and it will also impact the way sound hits my ears. But it's the dog days of summer and it feel fantastic!
