Yep, for me in my last band the bass sound, which included some gain/drive, was an integral part of the bands sound so to us it was essential to have it constant, hence the preamp - not all amps could do that sound, some couldn’t get anywhere near.
Whereas in my current band the bass is being a - what I call proper - bass so I’m less precious about the sound, I can get what I need from pretty much most amps.
And if I have to use my own amp I’ve found that my Ashdown RM500 seems to suit the band better than my ABM600.
