My active NS Design Radius CR5 has an 18V preamp and actually has lower output when dimed than my AmStd J5 unless I crank up the bass and treble controls.
A Sadowsky preamp has 0dB of gain until you turn up the tone controls. Set them full CCW and toggle from passive to active and the level stays the same.
I guess people just use a lot of EQ boost on their active basses. Most onboard preamps can boost each band 12-15dB.
If that's the case then the OP is only correct in that it lacks a pad function. They are not correct that it's not an easily resolved concern that anyone can easily address using only the volume knob on their bass with no additional purchases or gear to connect. I don't have access to a gen 1 or 2 Scarlett 2i2, but if anyone wants to send one to me I will happily demonstrate just how simple this really is.
Yeah, I dunno, I tend to defer to y'all on these matters as I'm certainly no expert, I'm just saying I had the same experience as OP - I couldn't get my active basses to not clip on a 2i2 unless the gain on the interface and the volume on the bass were at near zero and I played with a very light touch. Didn't have that problem with the 2i4 or any other interface I've had. Google suggests a lot of bass players have this issue with the 2i2 which is possibly part of why it's been tweaked in software, etc, since the third gen (as suggested in the linked comment from Focusrite in the original post).
but sharing my experience that you might consider.
