This is right on. IME, these basic concepts are not put into practice very well. The volume and tone knobs on our guitars are there for a reason and they actually work. Low cut is a great tool and 170Hz is not brutal in any way. The majority of guitarists employ too much low end. I really dislike playing bass with those guys. Invariably, it is a muddy mess. Many musicians don't know how to allow space in the room. For me, it all starts with the drummer. The drummer sets the basic level in most cases. I love it when I ask the drummer to play louder, but it almost never happens. How to achieve a dynamic, balanced mix with space is different in every band, but it is almost always a combination of the points Don(and others) mentioned. YMMV...
I was a newbie to it all until recently & honestly was surprised at some of the advice & opinion that circulates. I was getting super frustrated... Got kemper expecting (I know... Wrongly) a use out of box experience but I was waaaay short in live setting with both Kones & cab. I've probably spent way more than needed to get there but hey it was fun & good experience.
Most online articles say cut under 100 Hz. One said "some players even go up as far as 150 to 180" hence my post wording.
I play with a very hard hitting drummer plus a lead guitarist who sets his level very high, esp on leads, and it took me a while to figure out that I was as near as dammit to "good live tone" but he was a major part of the equation. That might sound "duh" on here but it is a hobby & not a job for me. Playing live certainly. 20 years of bedroom noodling then a late in life band join isn't great schooling.
My point was, that for users like me, just saying "get the right profile" isn't wrong but it risks frustration with an inexperienced user. I'm now using a profile I have had for 2 years with frustrating results & now crushing it. The only variables there are 1) having the chat about band dynamics & 2) EQ.
Post I'm replying to confirms that. Tone knobs, low cut, dynamics. You guys might think that's a no brainer but to a relative newbie, it isn't.
