I'm mainly playing a Fender American Deluxe Jazz 5 w/onboard Sadowski preamp in front of the Noble. I'm preferring to dial back the Sadowski's treble to about 10-20% on and rely more on Noble's treble, which sounds a bit richer and more natural. But the Sadowski pre's bass signal boosted to about 50% with the Noble's bass boosted to same or even higher sound terrific together -- especially with the HPF engaged. It's funny how a few years ago everything (for me) was about the lower mids. Lower mids, lower mids, lower mids. Ridiculous obsession. And now I don't even have a lower mid adjuster - nor do I miss it!
