"5 Way Mid-Selector" on Ampeg SVT-CL

classix · #1 05-30-2009, 01:33 AM

What exactly does this do?
How does it work?
What is the difference between each position?

i looked all over the internet, and the forums, and didnt find anything.

And whenever im playing and change the selector, i cant notice any audible difference.

Thanks guys.

The selector is for selecting the mid freq you want to boost or cut. If your other mid knob is set flat, you won't hear a thing. It's only when you boost or cut you can hear it working.

8. FREQUENCY: Allows you to
select the center frequency for the
Midrange control (7), giving you a
choice of five “voices” for the
Midrange. The center frequencies
are (from left to right) 220Hz,
450Hz, 800Hz, 1.6kHz and 3kHz.

from the manual

still a little confused, but ill do some more research, thnx guys.

You won't hear the change if you have your mid knob set to 12 oclock. Rotate that one either way then move the 5 position switch to hear the changes. It just selects what pitch the your mid knob is altering. Make sense? I'm not a great communicator haha.

i see i see. so will the mid knob still alter all the mid frequencies, but the one on the selector more. or will it only alter the frequencies the mid selector is set to?

again, thnx. i love this forum because everyone is so full of bass knowledge! XD

That's a good question that I'd also like to know the answer to.

anything?

It's like a semi-parametric....... The selector sets WHAT you boost/cut, the other knob selects HOW MUCH you boost or cut.

They work together.

I noticed on my CL that the tone controls don't do much. In order to hear any pronounced difference with the 5 way switch I had to either dump or dime the mid knob. Still an awesome amp, and when I'm famous enough not to have to lug my own gear, I'll have another.

So all the mids except the selected band stay about flat?

The Mid Knob Adjusts the gain of the frequency you have selected with the 5 position mid switch. Understand?

HogieWan · #13 05-30-2009, 08:31 PM

turn the mid all the way up, then play with the selector

classix · #14 05-30-2009, 09:04 PM

kk. so the mid knob ONLY adjusts the frequencies that are selected....

i get it. thnx guys.

Jim C · #15 05-30-2009, 09:15 PM

You have to understand the basics of tone control
The width of this center point (refered to as the "Q) is not adjustable so, yes it does have some affect on surrounding frequencies; it does not create a notch at just one point. There are equalizers that have adjustments that determine the width of the center frequency; the SVT does not have this feature.

Doing extreme mid cuts/boosts are the best way to learn how the midrange "works", and how to tailor it to suit your needs.

You guys got your hands full with this one. I'll just subscribe and see how it turns out.

True haha. It is hard to explain this with words. I usually do drawings for people that have never dealt with EQ before. It seems the OP gets what we are saying sort of though. The best way to explain it is picture every frequency laid out on a horizontal line. The Mid knob is going to make a broad dip or bump in that line (not a notch), depending on how much you turn the knob to the left or the right. The selector switch changes where that apex of that bump will be along that line. Does that make more sense? So like they said above, all the surrounding frequencies will be affected but the frequency that is selected with the 5 way switch will be affected the most. Maybe that cleared things up.

FletcherML · #19 08-23-2010, 07:17 PM

Try turning your mid nob all the way down and then switch through each of the five options while playing your bass. you'll hear some crazy changes.
And for the dude who said the eq knobs don't make a difference on the CL... YOU'RE HIGH! this head has more tonal variation, without delving into stupid effects and "super" "mega" "balls" buttons and swithces than Hitler had sketchy friends.
Learn what makes a good amp a good amp. There's a reason this amp makes everything else sound like a fairy.

SwamiRob · #20 08-23-2010, 07:37 PM

That was the same guy, perhaps it's you that needs to pass the dutchie to the left hand side and all that man (on the subject of dutchies I'm pretty sure the rig down at the Leeds West Indian Centre could make an Ampeg rig sound like a fairy by the way)

He didn't hear owt different because he hadn't fiddled with the gain knob of the mid character it would seem anyway pretty straightforward.

Alex explained how the EQ actually works pretty well though, the central frequency is where is getting boosted or cut obviously, and the more you take it down the more the surrounding frequencies will begin to be cut with it. A diagram would be better really, but to be honest it's better when things are left to your ears unless you really know what your doing. Follow the advice people have given though, play around with boosting the mid control and flicking between the 5 modes. If you hear something you don't like try gradually cutting back on it and see what it's like, equally if you flick through it and hear something you like then turn the control down a bit to make it less extreme and see what kinda tone you get there. Obviously you can only either cut what you don't like or boost what you do, but play about with it and see what you like the sound of best. When your comfortable knowing what your gonna get out of that then you can mess about seeing how it interacts with the bass & treble controls and the mega bright & balls deep switches too.
