Rack EQ Graphic or Parametric

[guitarobert]

I run a Boss GE-7 graphic EQ pedal always on in the effects loop of my amp and leave it at the same setting. But I want more control. With this in mind I'm considering buying a rackmounted EQ.

The question is: Which is better, graphic or parametric? I've heard it said on multiple guitar forums that a 30-band graphic EQ kills the tone of an amp. Is this true?

I was considering buying a parametric EQ (for example, a Rane PE17). I contacted the manufacturer and they recommended a 30-band graphic EQ instead for live guitar use. Now I'm confused! They suggested it would be much easier to set up.

The drawbacks I can think of for a parametric EQ are a potential limited number of bands compared to graphical EQ and more time getting it set up. But I'm not intimidated by the task. I think by using my ears it won't be difficult to set up. And I don't see the limited number of bands as a huge drawback since I currently have a smooth "curve" drawn out on my GE-7.

But are there any drawbacks to a 30-band graphic EQ? Is it true that it is a tone sucker? Also, any advice on a particular EQ unit (graphic or parametric) to use in a rack with a guitar amp?

Parametric is what I'd choose. Tone suckage depends upon the unit in question. It's like asking if a boost pedal will suck tone. It depends on the unit.

i Run 2 Ge 7 Bands in my Setup
one in the front and one in the loop since My Digitech 2101 has a Parametric EQ in it i use that too

i have to agree with Code 001 with the suckage
but over all the Rack Parametric will be Quieter then The GE 7
Try one till you find the one that works for your setup
but i belive the more you add the more Noise you Get

The problem with a gigantic graphic EQ is that you have a bazillion bands that your signal is being run through, with the chance that they are all adding noise, and you will barely be using any of them.

You don't need that for guitar. That's not what they're intended for, anyways.

parametric in the FRONT!

i just got one of the old tc electronic dpe's... if you ever see it, buy it. it's like mods in a box AND it has a killer gain boost.

 

[gary666]

I had the same TC pedal for years. Incredible box, very powerful little thing. But anyway, a parametric is way better, who needs 30 bands of eq when five totally adjustable bands will sound a lot better.
And I always ran mine in fromt of the amp. More power in the loop,but it makes a killer stop box, basically.

Lol I said the same thing at Harmony Central the other day and got my ass handed to me. That place is doomed.

Thanks for the replies! Looks like the consensus is still that parametric sounds better.

I used to think that I needed dozens of bands, but I'm realizing that even on my current 7-band Graphic EQ I'm drawing a smooth curve with it. I could probably get by with 3 or 4 parametric bands.

That being said, any suggestions on a rack unit? Looks like the Furman PQ series was popular in the past, but I don't think they're made anymore. The Rane PE-17 looks good to me as far as current production units go. Any other ideas?

If it's just an even curve, you could even get away with one band. That's the beauty of it.

I would look for a Rane on evilbay. They can go for very cheap. That stuff does not hold value at all.

Have any of you guys tried this one, I've heard it's really good;

 

[OneArmedScissor]

No, but that's not really fully parametric.

Well excuuuuuuuse me!

 

[guitarobert]

Here's another one. 4 bands, fully parametric. Any comments on this one (Rolls RPQ160)?

might sell my tc dual parametric eq. if anyone is insterested hit me up w/ an offer.

 

[guitarobert]

Update: I ordered a Rane PE-17 and it should be here by the end of the week. I'll post comments if anyone is interested.

TC eq's are the best and they're a hell of a deal when bought used.

BTW, the digitally controlled 1128 graphic eq adds no noise at all.

so what's the difference between a parametric and a graphic eq?

 

[OneArmedScissor]

Graphic EQs only have adjustable level. Parametric EQs let you set the frequency where each band is centered, and the width of the frequency range it affects, which is referred to as "Q." Some also have options for changing bands between shelving and notch filter types, typically on the lowest and highest band, primarily so you can set the lows and highs to roll off after a certain point, or switch them to a regular notch type.

If you can find one - I'd give the ART tube parametric EQ a try. It is 1U tall, but only half of a rack space (unless you find the dual EQ model). So, you'd have to put it on a shelf - or wedge it between other components (if you want to get all ghetto with it).

It is very flexible and does allow you to make some pretty precise frequency adjustments. Not to mention that the tube input is very nice to have. I've used mine extensively over the years and it has never let me down.

I don't use a rack set up any more - just the Cobra and a couple of pedals. However, when I was selling off all of my rack equipment - it is the one piece that I wouldn't even consider selling (just in case I ever go back to rack rig). Hell...I might even take it to my grave.

Hope this helps you.
