SOUND ON SOUND

[joelonsdale]

That's very true - then it has to be equipment related and you should exclude one piece of equipment at a time from the recording until the noise disappears.

[Sam Spoons]

Yup, :thumbup:

Just sat down in studio (I use that term loosely...lol). Will report back after some investigation. I bet it's a bad pre.

...or phantom circuit. Can't be the guitars...but I swear I hear the resonance in my Larivee but maybe I'm trying too hard to hear it if you know what I mean.

Nope, wasn't preamp or phantom circuit.

12" on axis off 14th fret. Exaggerated picking attack to bring out the ringing resonance. Seems to really like C. No EQing.

Well I stripped down recording chain to Sennheiser MK4 > Steinberg UR44 > Reaper with no input plugins or track plugins > Laptop and Desktop. Monitoring through Paradigm Monitor 3 and Shure SRH840 headphones. I tried various rooms, mics, preamps, computers, cables and the resonance has not changed. I even tried changing guitars! Lol.

As odd as it seems, I've concluded that the resonance is coming from the guitars. Even when strummed acoustically (not recording), I can hear it. I can hear it especially well in the treated room but I can hear it in any room now that I know what to listen for. The open C chord makes it pop. Am I crazy? The offending frequencies are close but not identical in the two guitars. 1kHz plus or minus and other harmonics.

Thanks for the sample. The open G string sound after the strum is quite prominent.

There's also a beating sound. In the open C chord, there might be two G's, one from the open G string, plus a G harmonic from the C note on the A string. Maybe they are beating due to be slightly out of tune.

[Generic Moniker]

Thanks for listening! Yes, tuning is a bit duff. Do you hear the lasting resonance in 1 kHz range after fundamental G dissipates?

I suppose that's the G harmonic from C fretted on A string? Thanks for this, Tim.

Google tells me that 1046.6 Hz is C6. That roughly corresponds with the offending frequency I am hearing.

Do you get the same ring when playing a different chord (i.e. one that it is not in tune with)?

[CS70]

A different angle - have u tried a different room, chair, clothes ? :-D

There may be something that gets excited and start vibrating at a certain frequency someplace else... and it fools you in thinking it's the instrument.

I once spent lot of time getting crazy chasing a very odd sound, only to discover it was something completely independent vibrating near my desk only when I was playing a specific note on the guitar.

[shufflebeat]

If it's identical in two different guitars it almost certainly isn't the guitars that are causing it (what are the odds?)

Often the truth has already been spoken, Grasshopper:

Only commonality between the guitars is the strings - Elixer Nanoweb.

[Tomás Mulcahy]

Sounds like Elixers doing their thing. Adding extra harmonics (compared to, say, Martin strings) that sound like brightness to the ear, but come out as metallic harmonics on mic. I've found it's not really a problem in a mix, but I still don't like them.

This is a good call. Sympathetic vibrations. Any drums in the room? other stringed instruments?
