Suppressing cold/unwanted overtones

I recently recorded a track with a kalimba in it. The instrument produces a tone not unlike a marimba, but also a metallic, percussive sound that isn't in tune. On my recording, the low notes sound wrong because the overtones sound louder in the mix.

I've found I can suppress a lot of guitar scritching with a cabinet simulator, so I decided to run the kalimba tracks through a cab sim. This helps somewhat, but I'm not crazy about this solution.

Assuming different instruments can produce unwanted tonal byproducts, is there a way to either suppress or re-tune these frequencies?

Have you tried EQ'ing it?

Cab sim could be a good start.Maybe you could use EQ to tame those overtones from the impulse file itself, before running the kalimba through it (or something along these lines, as a starting point)? Convolution offers a lot of creative editing potential, a bit beyond just emulating cabs and spaces.

You could also try something like ReaFir

Just btw: Marimba is wood, vibraphone & xylophone are metal & all should be in tune.

"Spectral editing" is what you need.

CoolEditPro could do that...

This is a job for some sharp eq notches. It will come at the cost of some phase oddness in the sound, though. Be willing to compromise between removing this tone and maintaining overall sound quality.

xylophone is wood, xylos refers to wood :)
