Martingitdave is right. There is a lowcut filter. And the lows.also go through a limiter/compression stage

It is written in lr baggs patent. Here is what is written in the Lyric patent:



* The high-pass filter is set around 70Hz (box 10).
* Frequencies between 20 Hz and 250 Hz are sent to a soft knew limiter (12).
* Frequencies between 20-200 Hz goes to a RMS compressor (14)
* Theire is a notch filter at 60 Hz
It is a way to control the bass. Keep it tight.

patent "US2014/0205106A1"

I own both dpa4099g and lyric and I confirm that tons of bass are cut. it enables.to prevent feedback and gain some dynamic.

The only known cure is IR convolution like Tonedexter.
Here are samples



1) DPA 4099G
2) Lyric alone
3) Lyric + IR pedal (simple process)
4) Lyric + IR pedal (Tonedexter patent inspired process)

If you can't hear any difference between 1) and 2) then you should buy the lyric.
