Live guitar EQ issues

i use an Alesis DEQ in my guitar rack. i noticed last night while playing a show that i couldn't hear certain parts of our songs, but then other parts were very audible. i am boosting what i thought where the usual freqs for guitar, but i am wondering if not boosting mids at all is the cause of this. when i say boost, i mean maybe 4db max, and talking freqs from 200-600 and 1.6-6k.

i am very new to EQ, so any input would help and be greatly appreciated.

hey buddy, what style do you play? what amp? i would say that yes maybe having the mids way down in your boost pedal may be the issue. i know that alot of hardcore, metal, emo, and rock guitarists really like the scooped mid sound or like to have the bass and the highs way up with the mids way down. - i used to do that (basically because that's what i thought everybody else did). but i found that upped mids can add alot of tone and clarity to a nice overdriven / distorted guitar. it will help you cut right through the mix. if you have the bass and highs way up, the low end will be masked with the bass guitar and the highs hardly have any tone. that's why you need those mids up.
sooo don't be afraid to turn that classic metal V-shape in the EQ upside-down!

i am currently playing death metal/hardcore. basically some sweeps, tremolo picking and break downs, nothing new :p. both me and the other guitarist play rhythm and lead, just depends on the part. my guitar rig is very unconventional....

gt 8 used as pre amp going to
alesis deq230 EQ going to
bbe482i sonic maxi going to
200 watt solid state PA and out to

i know this is by no means the typical guitar rig/sound. but i love the set up, if only i could get this EQ issue figured out

thanks al ot for the info so far, keep it coming :)

If you have drums and bass and nothing else, then you could try a boost at 150Hz (no much deeper, or you will kill the bass) or something around 800 Hz. 1k can be nasty if boosted too much. I wouldn't boost the highs. You will fatigue your listeners.

I don't think I understood this right:

Are you using a PA speaker as a cabinet? or just a PA amplifier as a head? Is the gt 8 providing your distortion? and do you have a cab sim on your sound?

OK that makes scene. I was imagining a PA speaker with the tweeters blaring. :lol: Maybe a little boost at 10k, but not over 12k. Leave some room for the cymbals. They are supposed to fry ears.

In the end it's all about how it sounds. Doing it by the numbers like this hardly ever ends up making the final cut, but I hope it offers a starting place.
