5 from 5 Amazing low pass and high pass filter.

Very simple build, few components, and the results are impressive.

Someone said on a forum that low pass filters are very useful on bass, they help shaping the low end, and get a sharper tone. By suppressing some of the lowest frequencies, the bass sound is easier to mix with other instruments, and feels less muddy with gain.

I was curious to try, thinking that any Bass knob on a bass pedal would do the trick in a similar way, but i was wrong. This effect does a much better job, it allows to dial lots of interesting tones from any bass dirt effect.

Its quite surprising and addictive, i am tempted to use it all the time on my bass.

Here is my build report :

All my thanks to musikding and PPCB !
