I was just about late for work because of watching the video this morning. One thing that I noted was Roger's take on Midrange boost.
I am just curious how you guys operate your preamp. I know a lot of ppl run bass and treble flat. But is there any of you guys that boost bass and treble on your preamp?
I run my preamp flat and sometimes boost my midrange on my amp.(depending on the room)
Roger has me rethinking or second guessing myself. I think I will try experimenting. I normally line out my amp instead of micing it. The Full Range FOH speakers do not color the tone like a Bass cabinet does. What I am hearing thru my cab may not be even close to what the crowd is hearing.
Like many, I typically boost the bass just a smidge for fatness. That setting doesn't overwhelm the nice midrange presence of the Sadowksy J's (especially with the wonderful single coils). I've never, ever used the treble boost at all, and I love a bright tone. However, my cabs are very full range, and don't need a ton of goosing.
And, as you point out, a ton of bass and treble boost would do some very nasty things IMO to your sound through a large front of house tone.
This clip is from a while back, but here is a demonstration of the Sadowsky pre I did a while back with a relatively full range and somewhat 'bright' rig. This clip also demonstrates how you can get a pretty good 'pickup solo'd' tone while still keeping the single coils hum canceled by just moving the blend control 1% or so off center.
FYI! I can't imagine boosting the treble on most full range cabs. However, if you have an old school cab with no tweeter, it can bring out a nice 'top of the driver' grind to your tone.
Probably my favorite preamp. As I say in the clip, it is not a 'transparent' pre, but it is a darn good pre!

The F500/Bargantino AE410 remains my favorite 'Sadowsky rig' for a nice punchy, grindy, articulate tone in a mix. Fabulous!
