Hello folks,

Can someone explain the difference between hi/lo cut and bass/treble control?

Thanks

Phil

High or low cut is (like) super decreasing or eliminating the highest and lowest freq.s.

Bass/treble control sound like amp eq to me, is this about a gear or program you're using?

Thanks for replying Mertay

In Helix, cabs and IRs have high cut and low cut, amps have bass and treble, I'm confused blink.gif

The "CUT" removes part of the signal. E.G. Bass Cut, removes part of the bass frequencies. Then the bass and trebble controls allow you boost bass and treble. Some cabs are a bit boomy/bass heavy and benefit from a pinch of bass cut even though you might later add some bass boost smile.gif

Ah ok here's in use description,

Low-cut; Clean any sort of sub-bass rumble you hear with this (check with headphobes, play mutes powerchords even on clean to check such rumble). There are other uses for this but lets talk that later.

High-cut; You probably won't use this so much since you have ir's. But if your guitar tone ever turns out to be too bright/sharp for a backing track try it first before reaching to amp eq's.

Hi Phil - I am guessing this relates to my comment about too much bass in your REC sound.

Usually all you need to do is turn the bass knob down. And remember a nice and bassy sound which sounds large on its own - is usually way too bassy for a mix. Best is if you try to tweak your sound while the backing track is playing - you should notice how it's easier to balance the levels (backing vs guitar sound) when you turn the bass knob down.

Thanks Mertay and Kris,

You are right Kris, it does relate to your comment, see I do listen wink.gif And thanks Mertay, you last comment helped a lot.

Cheers

Low Cut


Hi cut


An amps mid control will be a fixed frequency Peak with a certain width (Q) The knob will affect the amound of boost or cut (depending on the amp design) this frequency peak gets.

So is turning a high cut knob fully clockwise, the same as turning a treble control fully anti-clockwise?

Thanks smile.gif

Nope, high-cut only removes frequencys while treble increase or decreases them.

Best way to learn is by ear, always experiment with such knobs and try to remember by ear what they do to the sound.

Thanks,

I could hear a difference but I wanted to know technically what happens. That's me, I can't just accept things, like when I asked a friend what chord he was playing and he said "A7" I asked what the 7 meant, he just said it's the name of it. I can't do that, I have to know why rolleyes.gif

Cheers

Generally, yes. A high-cut filter, which is more commonly called a low pass filter, when turned all the way open, will allow the sound through unmodified.

Unlike a lowpass filter, there is no universally accepted definition of a "treble" control. On guitar amps with passive tone stacks, the treble control is often a low pass filter. So, yes, a treble control is often a low pass filter and should function the same. Tone stacks on guitar amps have various designs though, so this comment applies to many, but not all amps.

In any case, filters, especially on guitar amps, often color the sound slightly when all the way open. So, comparing a particular highcut control to a particular treble control may sound different when wide open.

This might help. Think of HIGH and LOW "Cut" as using scissors to actually "cut" either HIGH (treble) or LOW (Bass) sounds out of a given signal.

HIGH PASS and LOW PASS filters, let either HIGHS or LOWS "PASS" much like Gandolf stood on the bridge and said "none shall pass", if he was a "HIGH PASS" filter, only "HIGH" (treble) sound could get by him, if he was a "LOW PASS" filter, only LOW (BASS) sound could get by him smile.gif

Lord of the Rings Analogy! smile.gif

With Guitar amps, usually the bass and treble are at "fixed" frequency. They can't be changed. All you can do is choose how much or how little of each you want by turning each knob. The bass and treble frequency has been chosen by the builder. With a PARAMETRIC EQ, the user can determine what frequency (high/treble or low bass, or mid range) is being impacted and how much and how severe. The "Q" determines if the cut/boost is a large smile curve or a sharp spike type curve.

Hope this helps smile.gif

Kris has a point with bass. Usually if it sounds good by itself, it may be too bass heavy for a mix and won't "cut through". Usually you can "pre eq" (e.g. put in your equalization before your gain stage) your signal to reduce bass before it gets turned to mudd by the distortion / gain. Reducing bass on input like that can make a guitar sound "tight" where adding too much bass on input can result in a boomy sound that cuts through poorly. The easy thing to do is just turn down the bass on the amp head in your sim.

Does the age restriction at a pub mean you have to be above a certain age to get in? Or does it mean if you're below a certain age you're not permitted to enter? smile.gif.
