Yes, when playing with a band, sometimes the frequencies that you dial out can sound like there's a hole there. That CAN be a good thing if it meshes with the frequencies your bandmates are using. That low-mid control effects the 'main body' of your sound (stolen from Bob Gallien)....dialing that down too much leaves you with...not much.
Totally true! That lo-mid is key! Truth is, for a solid slap tone, the frequency I like to scoop is usually 400-500hz which is right in between the lo and hi mids on the MB210.
A couple of things: 1) I definitely have my lo-mid the opposite of scooped now. It's at 1 or 2 o'clock and adds some legit punch to my sound.
2) I've been playing around with the hi-mid and I think I like it at around 1 o'clock as well
here's my question. By raising the lo and hi mids, am I essentially scooping the frequencies in between them? So, the lo-mid controls 250 hz, hi-mid controls 1k hz. To scoop at around 400-500 hz like I like it, I just boost the two mids a bit.
Essentially I'm finding that if I want some more low end from my amp, I need to crank the lo-mid, not the bass knob and likewise, if I need more high-end, then crank the hi-mid up, not the treble.
So my bass stays permanently at 10/11 o'clock and treble permanently at 1 o'clock.
Lo-mid ranges between 1 o'clock and 2:30
Hi-mid ranges between 12 o'clock and 1 o'clock
Bass ranges between 10 and 11 o'clock
Treble at 1 o'clock
Definitely would have to agree that the Lo-Mid is the life-force of that amp. Just putting that out there for anybody else struggling to dial in a good tone.
I'm sure you're all getting tired of my postings... just trying to help.
