[Ghost Hip]

I just use the one on my amp.

That's plenty for most people!

That's what I meant. I've never felt a need for using shelving EQ, but I guess it can be useful in some situations.

Logic's EQ is so damn useful though.

Right on. I feel the same way about shelving EQ's. I guess apple introduced 64-bit Logic Pro 9.1 at NAMM so that should make those EQ's sound even better!

I vote paramentric EQ.

[Dr. Sherman Sticks M.D.]

i just picked up an old mxr dual 15 band graphic on ebay for next to nothing!

im thinkin a parametric would be more useful tho. i dunno.

we'll see how it works out.

Sweet. 15 bands should be plenty for guitar EQ applications.

yea it looks pretty righteous, im pretty stoked about it.

i'm actually lookin to use it to liven up whole mixes n stuff. boost certain freqs when needed. sometimes shit gets lost by the final mix.

I thought MXR just made a 5 and 10 band pedal. What's the model number for the 15 band one?

[Dr. Sherman Sticks M.D.]

model 124. its a rack piece. they had a 31 bander as well which i believe is model 125.

Nice! I didn't know MXR made rack mount effects. Looks like you got it for a sweet price too! Let us know how you like it.

me neither! i was just lookin at EQs on ebay and stumbled upon it. the rack ears are pretty beat up but i dont really care/might try to replace them if i can.
i love those blue faces.

Let us know how you like it.

will do! thanks again for the help!

No problem.

EQs generally have three parameters. Frequency, amount of neighbouring frequencies affected (known as Q), boost/cut amount

Parametric EQ will let you choose the frequency, choose the Q, and choose the boost/cut amount

graphic EQ only lets you change the boost/cut amount... but the frequency & Q amount are already selected in the design.
the more bands on your graphic EQ, the narrower each band is.
their Q is pre-set to overlap the neighbouring bands just a bit, but not too much.
you could use a graphic EQ to make wide band boost/cuts by combining bands.
it's harder to make notches, but a 30 notch eq will have each band narrow enough that they're effective notches.
i don't know of many people who would need a notch option in a pedal. (and studio grade graphic eq typically have 30 bands)
guitar amps are not parametric
bass/mid/treble knobs are just like a 3 band graphic eq. but with knobs instead of a up/down slider like in a graphic eq.


there's no reason to hate graphic eq's so much. there isn't one build equal.
ever come across a parametric eq that had Q linear weighted?

[Dr. Sherman Sticks M.D.]

what does this mean?

very nice description too btw.

[oinkbanana]

typically the Q is log weighted & you have equal octaves on each side of the selected frequency (fraction octaves if you want)
eg: you select 440hz, and a Q of 2 octaves wide... so you affect 220hz to 880hz

but if it's linear weighted it'll have equal frequency on each side of
you select 440hz, with a Q of 2 octaves wide you affect 176Hz to 704Hz.
so the centre frequency changes as you change the Q.
(I'd say this is an example of a very poorly designed parametric EQ)
they'll never tell you in the manual either.

i just use the tone knob on my guitar
