virtual capo and natural resonance

I've searched around the forums a bit and found some postings that are somehwat related to this, but I didn't find exactly what I am loking for.  Hopefully someone here can provide some feedback.  Speaking of feedback , that's part of my question.  I'm wondering if my guitar would be as responsive in the respect of positive feedback from the amplifier causing the the string to keep resonating at the frequency that the amp is amplifying.  Since I am using virtual capo, the string isn't actually vibrating at that frequency so I might not get the cool feedback or even extra sustain I would get at stage volume normally.  Have any of you found that to be the case or have thought about that?  I know this wouldn't be particular to the JTV, but that's what I am considering buying, so that's where I'll pose the question .

 

Along the same lines, the normal sympathetic vibration of strings wouldn't be the same if I were using, for instance, an open D virtual capo tuning.  Depending on what I was playing, the actual string vibrations might get pretty dissonant to each other and negate sustain and normal harmonic "interaction."  If I'm playing something full bore distortion metal, that may not be a big deal (and I wouldn't be playing in open D either), but playing clean arpeggiations that ring together the problem might rear its ugly head..  This would only be an issue with open tunings as opposed to when all of the strings are still at the same relative intervals.

 

Am I just a worry wart?

    Hi Grimm26 - I don't think you are a worry-wart at all if you are not familiar with any of the Variax guitars available.

     

    I can...and will only...speak from my personal experience using a Variax Electric Model 700 (I have 2 in different colors & want to get a third for spare parts, etc.)  In other words, please do not chisel anything I'm about to write in stone. Others may write different experiences based on their Vax knowledge and what amp they use.  I'm 99.99999% certain that this is the same or better based on how the modeling works in both the older models and any of the new JTV models coming to retail soon.

     

    I use my 700s through a Vetta combo for both live and studio.  The first thing I would recommend you to do is stop thinking in the conventional way.  Any model Vax in their modeling mode are exactly that.  Models of any guitar you've chosen, plus any alt tunings you've chosen and the strings respond in the manner closet to the real guitar you are emulating with any of the Vax computer based models.

     

    I understand what you are driving at with your concern about phase cancellation if you have a modeled tuning that differs from the actual string tuning.  Amazingly enough - when the Vax's are modeling in alt tunings of any kind - they respond nearly exactly as whatever "real" guitar you've chosen and alt tuning you've chosen even if this clashes, is dissonant, or most likely seem like it would phase cancel due to the physical string tuning not being in sympathetic resonance with the alt tuning.  Yes, this seems like it would be a problem, but as I said preciously - amazingly it is not!!  It seems that once you've chosen a guitar model, then an alt tuning, the modeled combination responds, sustains, feeds back, or whatever you wish it to do as if the physical strings were being tuned in an alt tuning with mag pups.

     

    Some additional bits of info on how to go about getting a good clean sound with or without a Line 6 Amp/Pedalboard.

     

    The amp, or effects board, or whatever you use, etc. also plays a huge role in the end result.  For example, if you want to get a sound something like The Edge gets...Using Workbench...Choose the Firebird body, put a LP Deluxe pup in the bridge position with a 5 to 10 degree angle counter-clockwise which will accentuate the B & E strings , then add IN SERIES, a P90 in the Neck slot pulled down to mid body, then slide it back up about the width of the pup closer to the fretboard with no angle.  Leave them IN PHASE, then change the volume pot to 250K ohm and the tone to 100K ohm resistance.  If this is not clean of twangy enough for you - change the P90 to a Tele Neck or Strat Neck pup in the same position long with all of the other settings as already stated.  +2db gain on the Bridge pup. 0 gain on the Neck pup, and 0 Gain on the overall Vax output.  Then change your tuning to Open D.

     

    The following is if you have a Line 6 modelling amp or something similar...The amp settings should be something like a Fender Blackface or Twin, Matchless, Roland Jazz, or even the NO AMP setting.  Use the optional SM-57 mic set very close or if you prefer a bit fuller overall sound - the 67 condensor mic, OFF AXIS.

     

    If you have a standard non-modeling amp or effects board, then just fiddle with the gain first with all tone knobs on the amp set to the middle, or 0db if using plus/minus settings, then once you've gotten the initial clean tone you are looking for, then tweak it AT LIVE STAGE VOLUME if you are setting this up to play live.  Big - yet common mistake - by most players is that they do not set up their amp at live stage volume settings and although it might sound great at home, it will certainly not sound the same when turned up even a little bit from how you had when tweaking your patches.

     

    I'll apologize now if you already knew most of this stuff, but I'm just trying to be thorough in my answer to your question in the hopes it might get you the desired results as quickly and simply as possible, no matter how complex this might read.

     

    You will certainly get much more punch from any amp when it is running at a reasonable (not deafening) stage volume.  And you'll find that this clean Vax patch will work very well for squeaky clean to slight growl based on your use of the volume knob while performing as well as the tone.

     

    Lastly - non-modeling solid state amps will punch much quicker than tube amps, but they are also almost always more brittle sounding, so just tweak at stage volume accordingly based on your amp if 100% Solid State or Valvestate.  Tube amps will REALLY punch when the mid/high mid is brought up a notch or two while playing with your stage volume.  And of course they WILL break-up/get gritty much faster than Solid State.

     

    Sorry this is so long to read...but I hope it makes sense and give you or anyone else who reads this some insight on your question and how one of the many ways a very good clean to gritty sound can be achieved using Workbench with whatever amp you happen to have.

     

    All the best,

    Neal

        Thanks the the lengthy reply, Neal.  I have a POD X3 Live that I've been using fior the past 2 years and that I would, of course, continue using with a JTV.  I've always gone straight into the PA with the X3L when playing out or rehearsing with the band and I run it straight into my IEM's when practicing at home, so I pretty much live inside the X3L .  The JTV looks impressive enough but its potential can really be unlocked with the X3L I think which is what tempts me even more towards trhe JTV.

         

        I really like the guitars that I have now, though .

        Sorry it was such a long response, but I did wish to make certain my ideas, etc were explained to the best of my ability to anyone who might not be as familiar with all of the things you can do with any Vax model guitar.

         

        I also agree that some of the new features offered with the X3L were available as an update for the Vetta combo.  Mainly - just the dual input independent routing. That is the single thing I will miss out on the most unless I can figure out a work-around way to use the 1/4" input as well as the VD input I currently use since they do work at the same time.

      Re: virtual capo and natural resonance

      Wait a minute...are you saying if you have your variax say tuned down a whole step, fret an A on the g string (which would sound a g) and hold it up to your speaker that it would feedback a G? I haven't tried this since I can't play at the volume it would take to create feedback in my place (boy, do I miss that!), but I find this hard to believe, since feedback is created by the speaker's vibrations causing the string to vibrate sympathetically. That string has no idea it's sounding a whole step lower, therefore it can't vibrate on the frequency returned from the speaker. Have you actually done this?

        Re: virtual capo and natural resonance

        Though it might not feedback exactly the same as it would, as the overtones would be different, it seems like it could lead to some very interesting sounds.  I haven't been in a band that used much controlled feedback in over a decade, but I used to use it a lot, so I'll be excited to fool with it.

        Yep - strange as the physics of this might seem...yes, you would get feedback of the note you are playing.

         

        If I get a chance, I'll post a demo of just that type of thing on YouTube and link it here as well.  Of course, this is not the same as the kind of thing you can get from a properly set up full blown Sustainiac or the other Fernandes version.  But what the current Vax models can do would certainly keep Ted Nugent happy and I don't even have to play a giant hollow body guitar to do it.  :-)

          Yeah, I forgot to suggest if you can do it to post it on youtube with your others. I gotta hear it to believe it!

          Re: virtual capo and natural resonance

          I respectfully disagree here. You can get feedback, but its not the level of intensity/ease that you would get from a non-pitch altered string. The reason is that its much easier to get the ringing string to vibrate as a result of amp produced sound wave energy if its the SAME frequency which the string is vibrating. This is what the previous poster was driving at. Additionally, you are much less likely with a digitally induced altered tuning to get harmonic feedback which triggers higher order even harmonics for the same reasons.

            Well - there is no point in discussing this further since I KNOW the physics, but I KNOW that it can be done.  I KNOW both of these facts.  They are not speculation, they are not wishful thinking on my part, but facts that I have been proving true every week when I perform live.

             

            So, as I wrote previously - I will find the time in the near future and create a demo showing exactly what I've been saying is possible and then after everyone sees and hears that demo - they will know that what I said was possible, is possible.  And if any other player can not get the same response from their guitar and amp - I'll do my best to assist in getting the same or similar results I get from my equipment.  Fair enough?

              Re: virtual capo and natural resonance

              Please reread what I wrote . I did not say there wont be feedback, in fact I said there WOULD be feedback, but that it would not have the intensity as if the string was not alternately tuned.

               

              It comes down to whether or not it makes a difference if the resonance frequency of the string (as determined by string length, width, tension) is different from the incoming sound wave frequency.

    Am I just a worry wart?

    Well, I will tell you this. It will feedback in any tuning, but here is the deal. It will only feedback and go into harmonics in standard tuning. If you are a half step down, it will feedback but not pop to the harmonic, it will just hold hard as if it is on the edge of popping into the harmonic without going there.
