I actually had problems with the sounds in the video above but after I did the velcro thing it dissipated.  As far as changing strings I change em one at a time but when I put the velcro on it I did them all at once.  Its no biggie, take in mind I am not a luthier I am just a hobbyist.  I think everyone has a opinion on how to do things you just have to find you own way. I posted the picture of my bridge I used a heavy duty adhesive velcro and cut it about 1/8 of a inch wide.  Laid it across right up next to piezo.

Hi Katie,

 

Thanks for your query.   It seems to be noticable on clean tones with or without effects (but worse with delays)  and with an AC30 Preamp emulation going into my DT25.   It is especially noticable when you slide from one note to another as opposed to just lifting your fingers off of one fret and moving to another.

 

BTW do you change all your strings at once so you can put the velcro across the bridge?  If so, is that okay to do so?   I always thought strings needed to be changed one or two at a time to avoid neck problems.      I'd much rather do it all at once however.     How close should the velcro  be the little saddle thingys (very technical term) that the strings rest on?  My little saddle thingys are not in a straight line at all so I could get my intonation right.  

 

Thanks for any insight you can offer.

Oh by the way I was gonna ask have you tried just running the HD500 with headphones with out the DT25 seeing if its maybe the DT25..

@katiekerry

Everybody may change his strings by his favour, no problem. I was just smiling about the statment, that removing all strings could do any harm to the neck (and it was not your statement!).

But anyway I'm playing among other guitars a JTV-69. Due to the trem bridge it is a good way changing strings one by another. It will keep the tension on the bridge and tuning will become much easier. 

But I clean my fretboard and give a little bit of fretboard oil to maintain on the fretboard so I remove all strings first.

For the JTV-59 I don't see any benefit it changing the string one by one. But as written, it is a question of favour.

Yeah back in the nineties I had a  few floyd rose guitars that were floating.  talk about a pain to change strings, I think that's where I started one at a time.  But yeah I get your drift about the neck damage, But in his defense when you get your info from others who knows what they will tell you.  I have heard some crazy stuff in all my years.  And the sad part is allot of it comes from articles from our Idols.  I think I read once that Eddie Van Halen told a reporter that He would boil his strings in milk or some crazy thing like that..   For instance some people probable think I am an idiot for the things I say.  But enough gab for now

I have the same issue with my 69. I really don't think it has anything to do with sympathetic vibrations, since I hear the same thing when recording direct with headphones on.

 

The low strings just don't ring clearly when using alt tunings.

One of the biggest differences is the amount of cross talk is cut down ( arpeggios are much clearer and precise) when you hop between say the 6th string and the 3 string it doesn't vibrate to the other open strings.  So when your running the modeling or alt tuning there is less artifacts to process..  Also when you palm mute it sounds allot better for some reason.    But everyone has their beliefs or theories.  I would try it, worst case scenario you have to change strings again.  I would just run a thin strip ( I did about a 1/8 of a inch wide) right behind the Piezo pickups. 

 

I wonder if the problem is caused more by the pickup being "loose" in its pocket than by the free portion of the string vibrating?  In looking at some of the solutions, it seems like the foam is actually pressed up against the rear face of the transducer.

 

Another point that's always bothered me about the piezo elements is that the treble strings are free to "float" back and forth in a rather wide, curved area.  That's not at all what a properly dressed conventional bridge piece would look like.  On even mild bends, I can watch the string walk back and forth.   At a minimum that's not good for sustain.

"you had mentioned the lester model when this happens, Does it happen with all models or just the lester.  If its kinda a high pitch gliss type of sound You could change the impedance settings on the HD500 to lower the top end a little. ( you have to use the guitar input though not VDI cable) I have noticed a change in the highs when I mess with the impedance setting.  it says in the manual the lower the settings act as a attenuater for high frequencies. it may help reduce it possibly.  I really wish I could hear it though that would help allot.  is it the same sound as in this video.."

 

Sorry it took me so long to get back to you.   I have changed the impedance and it didn't seem to matter.   I have also taken the DT25 out of the equation with no change.   The only thing that improves the problem is changing the input from Variax to Variax Mags.  That seems to clear it up alot but then means I can't use any of the models and alternate tunings/capo etc.     I am not equipped to record the sounds it makes but will try to do something soon.  It seems to mainly be noticable when you do a slide from one fret to another on the E string (next to the B string).

seems to me like it could be a problem with the piezo. The best thing would be to give it to a service center, specially if you still under warranty.

I had the same problem when an update to 1.9 firmware resulted in a green light on my Model Sector knob. Here's what I discovered:

 

My magnetic pickups were ALWAYS ON.

 

So, when using alternative tunings in modelling mode, the mag pickups were adding THEIR sound to the mix, and totally screwing everything up.

 

The fix (for me):

 

Reinstall firmware 1.7, and then update to 1.9.
