cruisinon2 Posted February 27, 2014 Share Posted February 27, 2014 OK...I'll apologize for the length of this post up front. The only nagging issue I have with my JTV69 is as follows: Problem is limited to all the drop D tunings (drop D, drop Db, DADGAD, open D). Basically, when palm muting the open A string, and some fretted notes as well, with a high gain amp setting, I get some odd overtone(s) coming through...almost sounds like more than one string is being played...horribly muddy. Easiest way to hear it is crank up the gain, and just do some palm-muted chugging on the open A string...if I toggle back and forth with the alt tuning wheel between standard tuning and drop D while chugging away on the A string, its terribly obvious. I can work around it under certain circumstances by positioning my picking hand so that there's no contact at all with the low E string (which I kinda discovered by accident), but for some tunes contorting like that just doesn't work. Initially I had suspected that since avoiding the low E string seemed to fix it, that perhaps it had something to do with the piezo's sensitivity, picking up accidental noises just from resting my palm on the E string while playing. It never happens in standard tuning, or any of the other alt tunings...and this is what was nagging at me. Why some tunings, and not others??? And why only the various drop D tunings? I figured an overtly specific problem must have a specific cause. So I went into Workbench to do a little experiment.... I pulled up Lester-1, and I brought the A string volume all the way to zero. I then played just that string, carefully muting all the other strings down by the nut so nothing else would start ringing, also being careful not to touch anything with my picking hand but the A string. As expected, total silence. BUT...as soon as I layed the palm of my picking hand across the rest of the strings, (normal palm-mute, "chugging" position) playing the A string now produced clearly audible notes. With that string's output at zero, the only possibility that I can see is that enough vibration is being transfered through my friggin' hand that is then propagating along the low E string to that piezo saddle (possibly others as well?). I suspect it's mostly by the low E saddle, because one's hand will rest mostly on that string almost by default, when palm-muting anything...mine does anyway. It explains why this is only happening in the drop D tunings...when I palm mute and play the open A string, any resonance being grabbed by the low E saddle is then being detuned, and this has to be what's bleeding through. It also explains why it does not occur in any of the other tunings...in those cases, the low E piezo saddle is probably still picking up resonance from the A string, but since its not being detuned, is passes through unnoticed as the same pitch. I'm no engineer, but I'm pretty sure that this is what's going on...the quesiton is, is there a fix? Do I have absurdly sensitive piezo(s)? Or is my right hand too dense? :P Any thoughts would be appreciated....and thanks for reading if you managed to stay awake through all that!!
