I went to see my buddy's band tonight, and when I got home I made an impedance buffer. It takes whatever input impedance you put in (for example your looooow impedance active bass) and re-sets it to the perfect (high) impedance to run vintage fuzz circuits that have a problem with low impedance signals - like a fuzz face and derivatives.
I can now use my active bass with any fuzz pedal. "Bonza".
