Weird Ugly High Frequency


Best Answer DeanDinosaur , 12 June 2013 - 04:52 AM

Try EQ before the amp and/or after the amp or a combination of both. When using EQ before the amp, you can cut a lot of high frequecies without losing as much if you use the similar setting after the amp. Based on my experience I notice that you retain more authenticity of amp sound and character with the EQ before.

Hi, first since there are no dream rig section I don't know where to post this...

 

Guitar to hd500 to dt25 via l6 link in combo output mode.

 

Trying to replicate the sound of my dual rectifier and I'm pretty happy with my sound except an annoying high frequency that I can't name. Treble or presence dosnt seem to cut it. Now I feel like I hear that sound in all my patches, even cleans ones.

 

Anyone knows what I am talking about? Should I use an EQ to try to cut it without altering the sound? I'm afraid to use the mid EQ  boost technique cause usualy in metal sound we cut mids.

 

Thanks

probably the weird frequencies you're speaking about are the ones called "ghost notes"..
if so, they are simply part of the game..
several real amps exibite those weird frequencies expecially when cranked.. and that phenomenon is modeled as well along with other characteristics.. and by other modelers too

generally speaking about amps modeled or not, often even the small dissonances coming from our instrument are amplified as well, for example, the strings portions that are beyond the nut on the guitar headstock (or beyond the bridge) which produce dissonant frequencies.. In this case, you can put a hair elastic or something else over them to reduce the problem .. the tremolo bar springs can also contribute to this phenomeonon..

try to attack your ear to the guitar without amplifier, play some notes or chords.. any strange vibrations that may be present could be amplified, because they can affects the vibration of the strings as the instrument's body normally does..

back to the amp model another thing you can try is to reduce a little the amp model gain and add a distortion/overdrive to compensate

I doubt he's talking about ghost notes. Not all the amps have those but ghost notes  can be heard very clearly on some amps (like the Bassman and few others) specially when playing on the 3rd and fourth strings. You hear another guitar part just like a harmonizer except it's not in Harmony. I hear them all over the place using the Eleven Rack also. Line 6 and avid decided to model ghost notes, but fractal in the early AXE FX didn't model that, and I don't think they modeled hum. Unfortunately, if the high frequencies offending aren't removed or fixed by EQ, then they're just part of the modeling and the more you try to avoid hearing them, the worse it gets. Maybe a hardware pedal compressor infront of the POD might help clean that...

tx for answers. I'm currently playing with weird EQ's and reading that guy: http://foobazaar.com...uide/eq#effects

 

I'm pretty sure it's not ghost notes. Too bad they haven't modeled a pedal like mxr ten bands friendly EQ. If I have no solution in the end I already own that pedal so I'll put it in loop but I prefer selling it...

Well endless possibilities... curiously using the hi-watt cab remove the high crap and gives me more bottom. (on clean sound I hate Hi-Watt cause I feel too thin to do my pink floyd patch with it)

 

Playing with EQ's can change everything but I think it will take a while to do my sounds. The good news is that everything seem to be there and waiting for me to tweak it to my ears and taste. :)

I never heard "ugly high frequency sounds" .

My setup JTV-69, HD500 direct to Mixer (earphone at home, pa in rehearsal room and live performance).

 

What guitar you are using?

Is this sound also audible with no fx assigned to the patch?

Is this sound audible on earphones?

Checked all cables?

Checked your DT25 if no problem?

 

BTW: the mid focus eq leaves the mid untouched. It only cuts the high and the low frequency.

Keep the hi-pass filter at 0%, all low will pass the filter.

Use lo-pass Q at 60-70% to get a notch filter, then slowly dial down the freq to find the disturbing frequency.
