What The Hell Does A Resonance knob do?

Re: What The Hell Does A Resonance knob do?

IIRC, I think T dynamics blends in more fake tube emulation. (tube dynamics) So it's like being able to vary between a solid state sound and a solid state faking a tube amp sound.

Resonance I believe takes feedback from the speaker load and adds low end resonance that's supposed to be dynamically respondent. It loosens the low end.

You get more bass response. Think of it as adding more bass resonance. Too much will sound muddy, too little will make your sound tighter or less bassier. It's different from bass in preamp.
 
Re: What The Hell Does A Resonance knob do?

I've got the same amp, and Resonance really brings out the "lows", kind of like a "tight" vs "loose" switch, the more you crank the resonance control, the looser the bass response is, if you roll it back, it tightens the bass up. In the bedroom I have it dimed, but at practice I usually roll it back to 3-5 to tighten things up. The T. Dynamics control is like a "fake tube power" control. I find that the further I turn the T. Dynamics control, the more the amp "breathes" and opens up. It's much more noticable when you crank the amp. At band practice, if I put the volume up to say 8, and the T. Dynamics at 10%, it won't cut through the mix, but dime it to 100%, and you'll notice it. Think of it like power output, your using somewhere between 10% and 100% of the amp's power. Supposedly if you take it to 10% it's supposed to have that "tube-like breakup", but that just doesn't happen with transistors.

Resonance controls the low end frequency of your power amp section. This is different to your preamp bass knob because the bass in a amp will only cut bass out where as this resonance control will boost and cut out low end and this usually boost or cut the 62hz which is important for the rumble or the huge omph that an amp needs so where you would want more or less usually comes to our different taste and sorry cant help with the T.Dynamics (Like some other people said you can made your sound more loose or tight the resonance so use it carefully to shape your sound.)
 
Re: What The Hell Does A Resonance knob do?

I've always thought of resonance as a very low end EQ adjustment - I'd say somewhere between 80 and 120 hz.
Great for making small cabs sound bigger in a room. In front of a microphone, no idea.

welcome to the forum Darkness
this thread is a bit old
and I think Astro has moved on to the Marshall tube variety

but thank you for you for your informed opinion

albeit about ten years late
 
Re: What The Hell Does A Resonance knob do?

Resonance apparently also makes threads come back to life 10 years later.
 
Re: What The Hell Does A Resonance knob do?

Oh crap, I didn't even notice.
I was kinda surprised our dear Astroboy wouldn't know about that. Forgot about necro threads. Damn.

Who Cares ? Awesome Topic ~ Resonance to Drop C is like Harmonics to EVH , just a important in many aspects ~ a Thing of Beauty

Re: What The Hell Does A Resonance knob do?

But how would cranking Resonance affect my sound?

this is an excellent question. amp makers know what touring musicians eventually learn. A loud amp cranked sounds different then an amp at low or medium volume. also noted is the number of speakers your using too. If you take an amp head-per say- and run it with the settings on that head set the same way into a single speaker vs a 4x12 cab everybody hear will tell you the 4x12 cab will add a substatial amount more of bass to the tone. Even a 2x12 cab will thicken tone and add bass- not as much as a 4x12-but it will add a certain amount of bass to the tone which some people prefer over a 4x12 because they claim it cuts through a band mix better. You can debate this all day long and there's also the hassle of hauling heavy cabs to a gig just to get a bigger tone or even just running that same amp head direct into a P.A. and simulating a different speaker cab sizes into the tone to adjust.
Most amp companies now will provide a resonance switch on the back of the amp because if you want the big 4x12 cranked loud bass sound out of-per say-a 1x12 combo at lower volume without blowing out your neighbors you can adjust your resonance tone to simply add bass to come close to that sound. You can also decrease resonance and crank up your amp to get a tighter chuga chuga tone with distortion or maybe a tighter spanky clean tone. You can also grab a 2x12 cab instead of a 4x12 cab and make up the difference by increasing your Resonance on your amp head. If you have a combo you may want to add an extension cab and adjust the resonance for what your trying to get too. Its not perfect, but it helps the amp from sounding really kinda thin and trebley at low volume when you really havent pushed your power tubes much yet at low volume.
remember too, if you gig out they will most likely mike one speaker so if you want it to sound a little fuller without diking around with all your knobs for a paticuler tune then you have the quick and easy option of just adjusting your Resonance control for the song or next group of songs in your set list. Again its not perfect but it can really help thicken your tone up or decrease it slightly to tighten up your bass tone.

I have an old 2 x 12" with even Older GM-70's that works Awesome for Low/ Deep resonance + ya dont have to crank any eq's ( we just pull-out the mids a bit <- with the Head I typically use thru it as a halfer
 
Re: What The Hell Does A Resonance knob do?

Along with " Loosen " I would have to say it Emphasizes or Enhances , as well - Frank
