Even more on the topic, a bit of a "story".
Back it my "BR*" days, when I worked at an unnamed bass-centric retailer in a Central Florida city for a few years, I got to know a fella by the name of David Nordschow. Nice guy, not a player per se, but someone with both an interest in our fair instrument, and the knowledge to do good stuff for it. At the time, he ran a little outfit called Eden Amplification, you might have heard of it

.
Once he was visiting, and my rig was in the shop for some reason or another, and he was noticing it had 2 of his cabinets, and his excellent power amplifier, but it had "another manufacturer's" preamp in the rack (specifically, Demeter HBP-1). He questioned me as to why I didn't have the Eden Navigator in there. My response will sum up my philosophy neatly:
"Too many f***ing knobs."
I did elaborate a bit, and he listened intently, and he "got" where I was coming from - mainly my previous post that between my primary tone controls (right hand, blend knob) and my secondary tone controls (3-band preamp built into bass), I had all of the EQ I would ever want or need, and all "more knobs" would do is give me the ability to f**k up my tone, not make it better.
He then jokingly said he was going to go back to his workshop and create a preamp with an input, a volume control, the ability to take a microampere signal from the bass and raise it enough to drive the input section of a power amp, and and output jack. He was going to name it "The Gard".
I was amused by this (and quite thankful he was not serious!

).
About a year later, the newest version of his power amp showed up, and he made a point of telling me that the input level on the amp was sensitive enough to be driven with an active bass guitar - eliminating the need for a preamp if so desired. I can't claim to be the inspiration for it, but who knows. I never asked, just said "good idea!". Never bought it, sadly, because I just can't justify carrying around a 1200 watt amp these days.
"Less is more" indeed.
