Here is a great bass overdrive by Zorg Effects.
Gabriel, its creator, shared its schematic on FSB for everyone to use.

Original info:
How many times have you plugged your bass into an overdrive pedal and being deceived by the output sound : no more bass, too compressed, loss of precision, not violent enough, too muddy... The glorious basstar can fix all these problems.
The Glorious Basstar is a 3 bands overdrive: it cuts the signal in three frequencies bands : bass/mids/trebles. Each band can then be saturated independently and mixed according to your taste. One can get a very large choices of sounds with a bass guitar. By choosing to saturate one band or another and then mix them with cleans band you can get back your bass, attack, precision and grain. It's the ultimate bass overdrive, but it's all up to you:
By saturating the bass, you'll get acid fuzz distortion.
By saturating the mids, you'll get vintage overdrive tones.
By saturating the trebles, you'll get more modern overdrive.
By adding clean bass, you'll get back subs in your tone.
By adding clean mids, you'll get back bite.
By adding clean trebles, you'll get back attack.
But you can choose to overdrive more or less each band, it's up to you to choose what fits you best...
Lastly, the Glorious Basstar can also be used as a 3 bands equalizer or a booster if you don't overdrive any band.
Here is the original video of his pedals (the Glorious Basstar is at 1:50)
