Filtering extreme frequencies on gtr D.I.s ?

[okgb]

A friend records d.i. trks on all gtr for easier editing over the over driven reamped gtrs
but some of the inaudible frequencies cause clipping
Passive filters are limited in the steepness of the slope ?  is it possible to make steep HPF / LPF
passively ? or what solutions work for you ? tia!

Where is the clipping? Is it from the guitar into the DI for the original recording? Or was that DI'ed guitar recorded too hot?

Seems to be " sub sonic " low frequencies that you can see clip on the daw but don't hear them, so
looking to filter before the recorder , HPF is something I think all mic preamps should have, but
wondering if this can be done before that even.

I see this with the majority of bass DI tracks.  Anything percussive spikes non-musical subsonic frequencies.  Amplitude is usually so high a 1st order filter wouldn't do much for you.  I either record low and without compression and filter later, or use a filter set before any tracking compression.

You could build any filter you want inside an active DI (I think they call them instrument preamps.)

I won't name drop but back in the 80's a well known bass player used a parametric EQ I designed (Loft 401) for his bass preamp.  I had tweaked the input gain so it could provide up to 20dB of input gain, and the input Z at full gain was >100K so it wouldn't load down a bass pickup.

With the parametric you can do plenty of filtering/sound shaping.
