Yeah man, not changing the tone is my main concern. I was fortunate that throwing the Audere Classic preamp on it didn’t mess the tone up. Trial and error.
I am also going back to passive basses. If I need a little extra, I can eq what I need and not have to worry about batteries but I can generally get the tone I am looking for without an eq. The first B-50 had Basslines in it but it had some major wiring problems when I got it so it had to go back. I really never got to know what they sounded like. From what I have heard they are really good pickups.
