Petrucci 5-Band EQ Settings

Hello Everybody!

I know it's hard to get the right 5-band eq settings for Mesa Boogie Mark series, so I have calculated the Gain and Q-setting, taken from the original Mesa Boogie drawings.

The original EQ have a Gain setting +/- 12dB.

Since the Kemper don't have a EQ finished with these freq, it's easy to put one EQ in Slot X (80Hz - 2200 Hz) and another in Slot MOD with 6600Hz.

Classic V-Curve:
80Hz = +10dB, Q = 1.17
240Hz = +3dB, Q = 1.937
750Hz = -10dB, Q = 2.12
2200Hz = +3dB, Q = 0.673
6600Hz = +9dB, Q = 1.0

Here are some Petrucci settings, the Q is the same as above.

Petrucci 1:
80Hz = +7dB
240Hz = +6dB
750Hz = -11dB
2200Hz = +5dB
6600Hz = +6dB

Petrucci 2:
80Hz = +10dB
240Hz = +3dB
750Hz = -11dB
2200Hz = +4dB
6600Hz = +7dB

Petrucci 3 (Mark IV):
80Hz = +3dB
240Hz = +1dB
750Hz = -3dB
2200Hz = 0dB
6600Hz = -2dB

Petrucci 4 (Mark IIC+):
80Hz = +3dB
240Hz = +2dB
750Hz = -7dB
2200Hz = -3dB
6600Hz = +0.1dB

Petrucci 5:
80Hz = +11dB
240Hz = +6dB
750Hz = -6dB
2200Hz = +10dB
6600Hz = +4.5dB

The last one is settings for a MXR 10-band settings:

Petrucci :
31.25Hz = +11dB, 62.5Hz = +6dB, 125Hz = +6dB, 250Hz = 0dB, 500Hz = -10dB, 1kHz = -10dB, 2kHz = -4.5dB, 4kHz = +5dB,
8kHz = +2dB, 16kHz = -1dB

Hope you all enloy this.

Hello!

This is the actual settings in Mesa Boogie Mark series. If you find a profile that have the EQ in the amp in OFF mode, then you can apply these settings.

I have tried these settings with some profiles of Mesa Boogie and I must say that the EQ settings "warm up" the sound. It depends what profile you choose and how it sounds, but if you take a profile and apply these settings, perhaps you have to tweak the volume of the EQ's.

I forgot that you have to use Studio EQs for these settings.

Hello Viabcroce!

How the Dynamic Voice is working is a little bit tricky. As you increase the Dynamic Voice, the function becomes more and more a V-curve setting. You can read more in the manual on the preamp how this function works.

You should be able to either turn this knob all the way down, or switch off this completly.

Hello Sledge!

Sorry, perhaps I didn't was clearly about how to set up these EQ's.

First you choose a Studio EQ for Slot X.
Set the Lo Gain at 80Hz, gain setting and Q.
Set Midgain 1 for 240Hz, gain setting and Q.
Set Midgain 2 for 750Hz, gain setting and Q.
Set the Hi Gain at 0.0dB and turn the freq all the way up.

Now select another Studio Eq for Slot MOD.
Set the Lo Gain at 0.0dB and turn the freq all the way down.
Set Midgain 1 for 2200Hz, gain setting and Q.
Set Midgain 2 for 6600Hz, gain setting and Q.
Set the Hi Gain at 0.0dB and turn the freq all the way up.

The Q setting for 80Hz isn't so important, so I did it like this. I think this works very well.

Yes I know, but since haven't done a 5-band EQ, this was the only way I could did it.
For the most time when you hear a guitar sound, it's only reverb or/and delay on the sound.

You mean how did I come up with the result for the Freq, Gain and the Q?
I used a RLC calculator for the frequencies for the eq online. Which freq bands, you can see on the amp itself, the Q setting you have to calculate.

I took the value from the resistor, inductor and capacitor for each band from the actual drawing from MB Mark IV series and calculated. Then I got the Freq and Q for each band.
