A HUGE surprise to me is that passive mode sounds significantly different than active mode. My Fender has the same preamp (Bartolini NTMB 4.7A/P) and there didn't seem to be much difference but I guess with fretless everything really jumps out at you. Passive mode has more mid growl and a more natural top end while the active mode pulls the mids back a bit, boosts the bass a bit and has a more hi-fi sound overall. I like active for the bridge pup and passive for everything else which is totally weird for me because I'm a self-proclaimed active kinda guy.
Definitely digging the sound though after I threw some nickel roundwounds on. flatwounds are just not for me, haha.
Glad to hear your enjoying your "honeymoon".
I have that Bart NTMB 4.7a/p as well in my fretted Clement and I had it previously in a Modulus Q5. I always used the active with the Modulus but I have been playing a lot of passive with the Clement. Getting some great sounds. I Love that configuration on the fretted... may have to go with it on a fretless someday!
Looking forward to hearing yours!
