From the vendor

id="tab-description" role="tabpanel" aria-labelledby="tab-title-description">

The Big Bass Drive is the first Bass specific project available from JMK PCBs! This monster of an overdrive is perfectly suited for the low end of a Bass Guitar signal, and provides lots of nasty grit and sustain, along with a healthy dash of volume boost and tone control. Check it out, even if you’re just going to build it for the Bass player in your band! Please note that while this effect is awesome for Bass, it has a really unique sound that can be used with guitars as well. If you play detuned or baritone, consider trying this circuit out as well.
