Default Metal mixing. Low frequencies to mono

Hi,

Is good idea to take from drums and bass all rumble frequencies to mono?

Bass tracks (low+mids) are in mono, but BUSS track has little room reverbs to create some space for bass and this create stereo image.

I'd put a high pass filter on the reverb return

Try it - if it sounds good it is good
There's a free vst here
https://www.gvst.co.uk/downloads.htm
(I think it's the 'Bass stereo imaging effect')

Depending on what you are going for, perhaps use a (small amount!) of chorus on the bass instead of reverb.

There is also JS Effect included with Reaper that will monoize frequencies below the specific frequency. And it is:
"Stereo Enhancer".

It has settings for crossover (split) frequency and then for width of Low and High parts separately. So you can set frequency to 150Hz and the lows to 0 or 20% of width and the upper rest keep at 100% or even make it wider ..e.g. 115% if you think it needs to

Thanks for answers. I made this simple as possible with no JS plugins. Bass folder has two tracks: low and high. "High" track include signal from microphone (cab and amp with overdrive) and this track goes to stereo reverb to simulate room. "Low" track is signal from line which goes to small room reverb but pins in this plugin are set to mono.

If you're looking for that big, thunderous bass guitar sound (assuming you have a clean DI), give this a try:

Duplicate the DI track, and label it "High." Label the original "Low." Add your favorite EQ (ReaEQ works a treat for this) and on the "high" track, add a high-pass filter (24dB/8ve works a treat!) somewhere between 125-160Hz. On the "low" track, add the same EQ (slope and knee frequency) but set it to low-pass. On the low track, add a comp, somehwere around 8:1, fast attack, slow release, dial it up for around 8-12dB of gain reduction, and normalize the volume. That should give you a REALLY solid, thick low-end on the bass. Adjust the knee frequencies on the two -pass filters to taste. On the high track, drop on an overdrive (TSE's "BOD" is a free emulation of the SansAmp bass driver and works pretty well for this), then a comp, 2.5:1-ish (medium-slow attack), max 6dB GR (leaves some dynamic life in the bass), EQ to taste, then drop on a stereo chorus to widen the bass out. The net result is that you have a juicy, wide, punchy mid and high with a nice growl to it, and an absolutely rock-solid low end that will just sit there against the kicks.

If you decide you need verb, I would leave the DI tracks alone, and just add it to the "amp" track.

And in answer to your original question, yes, it is best practice to keep the LF stuff in mono. The human ear is remarkably insensitive to directionality of low-frequency sound, to the point that below ~100Hz, you really can't tell where it's coming from. That's why mono subwoofers can be just about anywhere without affecting the stereo image. And that includes behind you! The LF content is also very sensitive to any sort of phase anomalies that stereo processing may introduce.

Thanks SoundGuyDave! My bass track is pretty much the same like you describe.

Where do you suggest chorus? On BUSS or "high" track?

Insert on the "high" track. Most chorus units have a "mix" or "Blend" control to dial in the intensity that you want. The TAL Chorus-60 is a freebie that I really like on bass, if that helps.
