Could someone please tell me what effect cutting or boosting the following frequencies has on bass tone/sound.....2.1 Hz, 3.5Hz, 4.5Hz, 7.0 Hz ?
It makes those frequencies quieter or louder. Sorry. They're all high mid / treble frequencies (assuming you meant Khz - I can't imagine any EQ providing a 2hz adjustment). If you've got dead strings and/or a woolly-sounding cab you might not hear anything. The lower end should make your tone more nasal.
Haha tes..I meant KHZ....what I asked was what (if any)discernable difference will cutting or boosting any of those frequencies have on overall sound....I always take out everything over 1000Khz anyway...these frequencies are selectable in my bass (schecter elite5)
Oh. Well if you're cutting everything above 1Khz at your bass, then boosting those frequencies later on will do nothing. It's like asking what is 0 x 10, it's still zero.
Honestly- you have the bass, right? You have an amp or some headphones, right? You have fingers too? You should be the one telling us what effect it has on the sound.
http://www.unitconversion.org/unit_converter/frequency-wavelength.html The frequencies you've listed(Khz I assume) cover what I'd call the upper midrange(2.1kHz is grindy) to the very highest treble(7kHz is sizzly).
Noooooooooooooo....those frequencies are in my bass treble control...I only cut everything over 1000khz on the amp......so does it matter?
YOU listen and TELL US. Seriously. What, are we using your exact same bass and exact same amp? EQ's on different basses and different amps do not all cut or boost on the exact same slopes, or to the same degree.
I understand your point....but I only wanted to know..in general how those frequencies affect the tone of the bass
well 1000k cant be heard by human ears so i think you mean 1k if you're going for a low, dubby sound, then those frequencies are of no use to you. leave it flat on the pedal if you dont need them.
Please understand I am not saying any of this to be rude to you- but if you understood my point, you would understand that the only real way to know how those frequencies affect the tone of the bass is to experiment and listen. We can type all day, words like "bright" or "growl" etc., but they really mean nothing compared to personal listening to the real sound.
Not to mention the point (that you already made) that your rig is probably not giving you a completely flat response anyway, so you might already be hearing peaks or troughs around those frequencies. Just tweak the EQ until you get the sound you want, then stop. Tweak it again when you take your rig to another room, or if you find it doesn't sit well with the other instruments in your band. Sooner or later you'll know which sliders do what.
