Sonuus guitar to midi converter ..or something else? Boosting Bass signal

[RAY AGAINST THE MACHINE]

I would like to boost the signal from Bass Guitar ,so that I can plug it in to the input of My Moog Grandmother or Moog Minitaur. 
Apparently I need something to boost the bass guitar signal so that it can actually be heard in the mix ! Apparently sonuus might be the solution!
It is said a preamp would be sufficient to boost the signal from my bass guitar ! 
I do have a Zoom B3 , but not sure if that is a powerful enough signal boost ! 
 

Fwiw I do know how to control the synths in question to accept the signal from my bass guitar.. This is done by turning the oscillators all the way down ,and messing around with the rest of the knobs etc . With the moog Grandmother I also have to have it on the Drone setting for it to work . As for the Minitaur,a key from the midi  keyboard has to be permanently pushed down/ engaged . A lot of faffing around ..

 

I do have cheap mini distortion and overdrive pedals but doubt they’d be powerful enough to boost signal . The problem is the bass signal is too low in the inputs of the synths !

 

Please could someone recommend something to do the job . 
 

Thanks in advance 🙂
