Practical uses for the 4 Band Shift EQ

Can someone help me understand how I might use this EQ? I'm not sure what the Shift knob in this amp models does. In the meantime I'm going to try to use it in hopes to find out how it works. Thanks in advance for any help.

iv. 4 Band Shift EQ

Honestly, I never use this EQ. It's not that it's unusable; it's just that you never really know what you're going to get. Read the description below and see if you could say, "Oh that's exactly what my patch needs!"

It provides 4 peak/dip band EQ's with gain denoted in db's already.

  • Lo freq - centered around 90 HZ with shift at 50%, about 2 octaves wide. Use to boost/cut thump.
  • Low mid - centered around 180 HZ with shift at 50%, about 2 octaves wide. Use to boost/cut punch.
  • Hi mid - centered around 1 kHZ with shift at 50%, about 6 octaves wide. Use make the tone more or less midsy across the whole tone.
  • High - centered around 4 kHZ with shift at 50%, about 5 octaves wide. Use like a treble control.
  • Shift - causes the low and low mids bands to shift from higher to lower center frequencies, while causing the high and high mids bands to shift from lower to higher center frequencies, as shift moves from 0 to 100%. Shift move the center frequency of each band about 1 octave from its min to max setting.

so this is a 4 band parametric EQ with fixed Q, and variable gain.  The shift knob moves all four center frequencies simultaneously either closer together at 0% or farther apart at 100%.  This one is poorly explained but one we should probably use more often...  good info in the video above too...

I had the exact same problem. What the heck is this? It started me off on a project to measure the frequency response of ALL the EQs available in the HD500. You can find plots here. Hopefully it'll answer your question on what it is (but not how to use it).

I know you've done a lot to clear the fog with EQ's and Thanks again. I remember most of your posts about them. Very Very helpful for sure.

I have an idea about usage of the Shift EQ. I'm not a pro, so I don't know if it will work... Probably, if you have 2 or more guitars in the mix, you could use Shift EQ to put one guitar more to the center of the spectrum, and shift another guitar to the edge(s) of the spectrum, so they won't fight for the same frequencies.

 

I'd love to hear from pros about that, though :)

That sounds like a good idea. Thanks for the reply and idea. I'm going to to try layering some tracks like this to see what happens.

not sure there is enough real spread to effectively separate two guitars.  What it is really good for is tweaking 4 separate parametric bands at the same time using only one FX slot.  The shift knob is essentially the Frequency knob on a regular parametric EQ moving all 4 at the same time.  Not the greatest idea but very useful.  I have been using it a lot since this thread got me to look at it again and it is really easy to use once you understand what it is doing.  You can also use it to find those harsh freq's to dial out by cranking the gain on them one at a time and sweeping the shift till you find the offender and then dialing the gain back down.  Now fine tune the other gains to get the tone you need.  It works wonders with the new 5150 by the way...

Thanks radatats. Using it to dial out offending tones the way you described sounds like a good way of using too. I'm going to try some stuff with but won't zone out on it, lol.
