Variax 700 with graphtechs.Problem (again)

Hallo everyone, I recently upgrade the variax piezos with graphtecs, and all seemed good until...I started played dynamically..

The wounded strings (E,A,D) sounded loud, pretty loud even with a very soft picking, while the unwounded strings (G,B,E) didn't sound at all.

I used the workbench to adjust the volume, but even with settings of 10% for the wounded and 100% for the unwounded didn't solve the problem.

I reflash, but again, nothing.

 

When I installed the piezos, I cut the wires, separate them, put the silver on the pcb possitions that was the variax before, and the ground (blue), put them all together, and solder them together with the green one.

 

I have a variax 700 with tremolo.Any help / suggestion?

        what i would  do  is  loosen  the trem block  mounting  screws..   slip a   piece  of   stripped  wire  between the  block  and   the  bridge  plate.. retighten    the screws.  this  will give  you  something   to  solder to.   now  youlll be grounding  to the  bridge  plate  like  my 300 is.  ive  had  no problems  with  mine.  the  other  thing is  check for  a ground  wire  at the  tremelo claw. if it  has  a ground  wire  you can attatch  to that.. also  check the  pcb isnt  touching  anything  like  the  trem block. theres  supposed  to be  a double  sided  tape  insulating  and attatching  the pcb.  if its   not  and the pcb is  touching  anything  .. you could be  shorting the board..

         

        seems  to me  that  if  3  pickups  are  loud  and   3  are  mute...   you  may  have   a short  or  have  done  something  wrong.  also  that one   may have a ribbon cable . if  so   reseat both  ends  in the connector.  when i did  mine  all volumes  were  equal. your  the  first  one  ive  heard  of  who  has  had  trouble  with this  so most  likely  you need  to check over   what you  did..
