I like the way your band does things. Bravo to you and your band for being "old school" in this way. To me, "old school" is the way live performance should be.
Nowadays, due to overly aggressive sound techs and general laziness like nobody wanting to transport amps, there is way too much use of IEMs and ampless gigs. Ampless gigs don't sound like live music to me, it sounds like someone trying to recreate a studio session in a live venue. It sounds like sound guys striving for perfection when live music is not a perfect art form. Musicians need to create sound from their instruments, and for bass, that should mean an amp is part of the bass guitar sound. It shouldn't be separated from the instrument- it is part of the instrument. An upright bass has a body which is a sound box. A trumpet has a voice, a violin has a voice. When you put bass guitar directly into a sound system without an amp, it becomes just a signal - it's not a voice, not something that is heard and affects the air in a room directly, from the instrument and the sound source, and it's coming from another location than the musician is performing. We should want to be heard from where we are playing, and directly affect the ears of the listeners. We bass players should always be heard in the room from our amps- with the tonality that we choose. It may not be what the sound guy wants to hear, but they are paid to work with us, not to dictate to us what our bass playing should sound like.
I like my Genzler 110 combo. It naturally produces the sound of the bass I'm playing and so sounds very integrated to my ears- a true extension of my bass. I think it's artificial to separate the bass from the amp and run it direct only. The combination of the two IS the instrument.
JJK, when we have to work with sound engineers, I prefer the ones like you are describing- the ones that celebrate the sound of your instrument, including your amp, and appreciate good bass tone from the bass/amp instrument.
