Title: EQ pedal recommendations
Post by: SineHacker on June 22, 2012, 03:33:19 PM
I need an EQ pedal to do one thing, cut at around 200 - 220hz for a bent keyboard that loves to churn out muddyness at that frequency. This keyboard is one of my main instruments that I practice and perform with, sometimes when I play live the in-house mixing desk will be able to do it, but my entire output for everything I use is a single mono signal so it effects everything. Still, for me it makes or breaks a gig if I can have that little dip.

So I only need 1-band, will probably be good if it is adjustable freq, and for it to be able to cut (which I'm sure most do). preferably with no hiss, cuz I deal with a mountain of that already!

how about

assuming the sweep covers the frequencies you want.

if you want a very precise cut that you can sweep i'd definately go for a parametric EQ rather than a graphic one.

If it's a narrow range of frequencies you want to take out, you could try a notch filter.  A simple passive twin-T circuit will have a pretty shallow notch, and if it's not particularly well-balanced the notch will be quite broad - more like a shallow bandstop filter than an proper notch.

It may be worth a go, for the sake of three resistors and three capacitors.  If you want to sharpen it up, make an active notch and choose the components carefully ;-)

I think I have some good twin-T circuits in a Forrest Mimms book, so will check it out -

yeah I saw the Artec pedal, seems like there are lots of cheap eq pedals listed on ebay, I just wasn't sure what any would sound like in that price range! any ideas on Artec?

I just need it to be as clean as possible so it doesn't interfere with my noisey sludge!

i just found this:

interesting! (though slightly off-topic)

i'm liking the 'throw words at it and see what sticks' technique of writing in english on that listing.

'Knob 0; leads your pickup sound more rich, fatty and worm by boosting the gain in a mid-range and reduce the low and high frequency range'

I'm not sure i want my pickups sounding fatty and worm!  :o

I got the Artec SE-PEQ pedal, it works a treat! I've only listened to the difference through headphones so far - but good studio quality headphones and it has a decent range - I will be able to test it out on a big soundsystem next week which is where the problem really started in the first place

came in a nice box with a battery as well - £35 seems a bargain so far (i'm a sucker for nice boxes)
