The day I learned this was the day everything changed for me.My Neptunium arrived, and the first thing I did was start playing around was the HPF switch. With the bass/trebel knobs at zero, I immediately hated the sound. Made my bass sound like a damn guitar! Then I turned the bass knob up and at about 10 o'clock all of the bass tone was back but without the excessive boom.
I'm curious how it works in more of a performance setting, but for trying it out at home, the HPF plus some bass boost lets me play a bit louder, keep the bass tone, but not vibrate the nails out of the studs. This is fun.
It works beautifully in a band setting.
