Need an experienced user of GNX to enlighten me

Hello all, anyone with a deeper understanding of this GNX modeling thing help me out here. Are the amp models that come with whatever unit you may be working with, dedicated models, or are they conjured up from the basic controls built into the units themselves?

I've just recently purchased a GNX 4 for my son and I also picked up a Genesis 3 for myself to mess with and well, I'm a bit confused. :? Guitar 3456 has those cds with a gazzillion amp models that the manufacturer doesnt have the resources to research and produce. Question is, did he take an existing amp model, and modify it to acheive new ones? It does seem to be what Digitech advertises. :idea: Through repeated amplifier saves, is it possible to turn a weak model into a high gain model? Hasnt worked for me yet. I have noticed that when you start out with a stock model, the tone controls are at 0. Mess with it and save it as a new amp and the new amp comes up with the tone controls set at what you left them at. I haven't figured out what I did with one amp that I created from the Rectifier model, but when I started with the first model I couldnt get the highs as high as I wanted. When I got it close I saved it as a new amp. Now I bring it back up to mess with the new model and I can drive the highs up much higher. What gives? :?

I haven't tried to make a Hypermodel with the warp thing yet so I'm speaking from inexperience. With two amps and cabs \"warped\", what are the settings going to default to on the new HYPRmodel? Maybe Guitar 3456 could shed some light on what is possible with these things from a \"start from scratch\" point of veiw. I find Digitechs aproach to modeling unique, but is it really as moldable as it seems?

I'm gonna go and play with myG3 now and see if I cant answer my own questions before someone else does.

  • To quickly answer your question, you need to save the hypermodel, not the preset to be able to warp multiple times. That's how you can get a bluesy model to be of higher gain, by warping your blues amp with say a rectifier. You actually change the clipping characteristic, indeed creating a new model.


    For the technically inclined:

    That doesn't directly answer your question but yes, the algorithm in the GNX4 has 5 basic building blocks which take some parameters (basically some numbers). These numbers for each of the building blocks are stored within the patches and they are what make the \"Amp/cabinet model\".

    The amp portion is modeled by a pre-distortion eq, a cubic-spline clipping section, post-distortion eq (NOT the tone controls, this is separate).

    The cabinet is modeled with a digital filter.
    The last stage is the Tone controls, the bass, mid-range, treble, presence, gain and level controls.

    By using warp you combine these numbers for each block (by averaging them at a ratio determined by the warp control) and therefore, once can say you have indeed created another \"amp/cabinet model\" being that the algorithm is being fed different parameters as the ones you started with.
  • Thanks AlbertA for the information. The link is quite interesting, but alas, me not understand too good.

    So, if I understand correctly, I need to use both amp channels to achieve a new amp stage to work with. Just modifying and saving a single amp wont do the trick huh?

    Also, a while back I asked for an honest review of the G3 vs the GNX 4.
    The consensus was that the two were worlds apart. Now that I have both side by side I can say that they aint too different soundwise to me. The G3 is definitely lacking in features as compared to the GNX's but I find that it is compareable (to me at least) to the 4. I've been a Boss user up to now and in fact purchased this G3 to use in the FX loop of my GT 5 and/or 3. There are just so many great effects capabilities in the GT's, but the modeling is just so WEENIEEEEE! :roll: Fizz! Garble! :evil:

    I'm still finding \"my\" amps in this thing but if I were to just go with say the rectifier and my GT, Man! What a difference! It sounds like theres an amp in the room! I forgot what thats like! :lol: So much life to the sound! I just wish I could hit upon a cabinet that was more transparent sounding. I find myself using the direct setting for the cabinets. Yeah its sharp sounding but it sounds clearer. Thanks again for the info.
  • Probably factory patches wise, they are not too different sounding.

    But you can do alot more with the GNX4 patches.

    tonedog, check this link out it explains how to build a custom cab model for YOUR amp needs.


    or you could always get the Eminence Modeling 12's they're seriously GREAT STUFF
