Equalizer help

Hello Im new, This is probably the wrong place to ask tho Im assuming most equalizer adjustments are fairly similar across all models. My buddy is trying to get me to sell his RP6 and Im having a lot of trouble figuring out the equalizer.

Ive tried for well over 3 hours now to understand how it works, my rp7 is a lot simpler, but so far it seems if I set all 3 frequencys at 5.00 and all gains at 5 it produces an ok distortion, far from what Im looking for and anything I adjust from there just makes it worse.

Can anyone explain to me or divert me to a link as to what each frequency is, which one is bass middle and treble? and how exactly the frequency parameters work? Ive checked the manual but it was far from helpful.

I tried using the winamp equalizer to locate the bass middle and treble frequencies that most effect the sound of an old metallica song and then applied those to the digitech they were 310 Hz, 1Khz, and 3 Khz respectively, but that just gave me an old timey radio sound were all gain adjustments did exactly the same thing.

Im a Noob when it comes to frequency, Any help is appreciated :) Thanks

  • Depends on the amp settings, but generally a mid-boost around 1.5-3k will improve the tonal qualities of the distortion. That's where a lot of the harmonic squeal is generated. Also depends on the band width, but I'm guessing you can't adjust that.
  • the amp has no eg settings I had a great sound on my rp7 before with this amp its only 15 watts but the rp7 has no bass frequency parameter. The RP6 has freq 1 2 and 3 it doesnt say which is bass middle or treble I dont know what Im supposed to do with it.
  • The Parametric EQ in the RP6 is quite different.

    There are 3 adjustments you can assign to individual ranges of frequencies. You may select the range of the freq from 20hz to 16K IIRC.

    Settings have points called Q which represents bandwidth. Higher Q results in narrower bands of freq affected by the FREQ amount you select. Gains then adjust the boost or cut of the selected band.

    EX: If you have freq 1 set at 500hz. That is the middle reference so frequencies above and below 500hz would be boost or cut depending on the GAIN amount. Neg gain means cut and POS no GAIN means Boost.

    So if you had a setting like Q=2, Freq = 1Khz and Gain = -8 you would be cutting midband frequencies.

    If you had a Q of .5, Freq 1Khz, and Gain of +8, you are now boosting frequencies with a wider bandwidth while affecting more frequencies of boost above and below the center frequency of 1khz. IOW, you have a much wider slope of affected frequencies boosted ( with gain setting) above and below 1khz. If the Q was set to 2, you have a narrower boost above and below 1khz.

    Think of it as a mountain that has variable width to its slopes. Higher Q means a narrow slope and steeper peak. Lower Q would mean a much wider slope.

    The peak is the center FREQ you select and that center freq can be moved from Low freq (.02khz) on up to higher treble frequencies. ( 16k)

    The GAIN amount determines the peak and valley created in the eq curve.
    With gain at 0, it's pretty much flat ( no boost or cut). You can go from -15 to +15 on this setting. Neg no's create a valley and pos no's create a peak where the center freq is selected.

    This type of parametric eq is common on sequencer plugin's for recording daw applications.
  • Thanks its making some sense now, but is it fair to say that the RP6 equalizer is limited then?

    The manual states, freq1 Q= 0.5, freq2 Q = 1.0, freq3 Q = 2.0

    Im assuming I can create then a simple low frequency boost by setting freq1 at 0.02 to create a shallower slope across a wide band of low frequencies. Is that right?

    But I can only use freq 1 for 1 frequency, I can't adjust the Q setting, so I could never create 2 identical slopes for the low and high frequencies?

    Which freq parameter should I desinate for low mid and treble? or do I still have the wrong end of the stick?

    Thanks for the help.
  • Ok tell me If ive understood the idea of this now.

    I desginated freq1 (Q0.5) as treble by setting it to 10 kHz to cover a wide width of high frequencies , freq2(Q1.0) is now Bass, I set it at 200Hz. And freq3(Q2.0) at 1 Khz to cover the mids with the steepest slope.

    Its not perfect but its not too bad, does that sound like Ive got the right idea of how this works now?

    Thanks for the help.
