    Hey y'all!

    I was wondering if there is a notch filter in pedal form or if it would be difficult to make? I know I can't do it, but I have friends who can wield a soldering iron.

    See, I have a problem with our rehearsal space. It has standing waves at around 120Hz. Really head splitting stuff! Now I'm using my fDeck HPF to get rid of it, but as you can imagine I'm taking away a whole lot with it.

    If it's only for the rehearsal space. Behringer makes a Graphic EQ pedal for Bass @ $25 in the states. Has a band right at 120hz. I'd do that for the pricepoint.

    I have the WMD parametric 3-band eq. Works great, but it's $200.

    the quality of your pedal chain depends on your weakest pedal. you may know it, anyway.

    Are you saying having a behringer pedal will some how mess up the chain?

    They may be a bit notorious but they do have some quality budget stuff as well.

    If the pedal sucks tone, then yeah, it might be an issue. Though, if it's only for rehearsal and won't be used live, it's probably mot much of an issue.

    Yeah, cheap GEQ might work. If you need a tighter EQ band, the Source Audio BEF Pro has some notch setting - I use this for a static cut at 300hz sometimes, but the notch can be moved.

    An EWS BMC should nip that right in the bud on the cheap.

    Plenty of random pedals from other obscure and more name brand companies suck tone to varying degrees.

    All I am saying is you shouldn't judge based on brand alone, I haven't used much behringer stuff but they have some well reviewed budget gear.

    Likewise many name brand companies have put out mediocre overpriced gear over the years.

    The BMC has a rather wide Q, which makes it the opposite of a notch filter.

    One great answer would be the Empress Paraeq, with the switch selecting the lowest q setting.

    The MXR ten band is also great and has a band at 125hz. A graphic eq pedal is in a sense a whole series of notch filters.

  10. You might try a used or inexpensive 31 band eq for that, it will have the right point and narrow.
