    OK. I was confused by your post. You are right. Problem is not Piezo. Sounds like you have a noisy channel in the main board.
  2. Charlie_Watt
    No. If the noise moved when you swapped cables, then the noise is before the cables - at the bridge / piezo.
  3. Charlie_Watt
    The problem followed the piezo from your explanation. I suspect you have a bad piezo element.

    I use a package called Transcribe on my PC to do this and it works great! You can shift the pitch of a song or the tempo or both. It also has a spectrum analyzer that tells you what notes are being played.

    Nothing bugs me more than a speaker cab or amp that buzzes. If there is a mechanical buzz that is not acceptable period.

    Hey - these companies want to do the right thing. What makes you think they don't?
  7. Charlie_Watt
    I have not removed one but I think I saw somewhere way back that it was just pressed on.
  8. Charlie_Watt
    It should not do that! There is something wrong if it does.

    If Monkey sees your Variax than the interface is talking. What version of Workbench are you using???
  10. Charlie_Watt
    I would not recommend changing the USB chip yourself unless you have done this before. It's easy to ruin the board. Changing the connector is not that hard as it is through hole. You need a good soldering iron and a solder sucker to remove the solder from the holes.

    You need to find a place to connect all of the ground wires. They are required by the Graphtech pickups. On my 500 I had to attach to the Flex circuit that was under the bridge. I scraped insulation away from the ground pad that was connected to the bridge itself and soldered all of the ground wires to this ground that is part of the flex circuit. There has to be a ground on your bridge so you can do the same thing.

    Sounds like it's defective.

    The piezos themselves will not do any compressing. They respond to acceleration input (from the string vibration)
  14. Charlie_Watt
    Higher gain piezos does not mean more crosstalk. It means hotter signal, yes but if you reduce the gain, the crosstalk is reduced also. Crosstalk is much more a function of the mechanical design. (I do this for a living too but for Hard Disk Drives) I have used piezo elements for measuring acceleration disturbances. I would feel comfortable modifying the input gain stage if I had to. I would first put a scope on the analog signals going into the A/D and see what they look like when I strum hard. If they are clipping there or exceeding the input parameters for the A/D, then the gain is too high and there is no way adjusting the string volume in Workbench will fix that. I have no idea how much headroom Line 6 designed into this circuit. That is always a Signal / Noise and resolution tradeoff.

    The good news is that the only change they need to make is to thread the other side. One problem with this side thing is that the string tension is going to try to pull the saddle sideways. There is nothing to keep it from being pulled sideways slightly. That may be fine but it's not an ideal mechanical solution. They did it because of the way the strings are held on that kind of trem bridge. The fixed bridge on my old 500 has the adjustment screw in the middle of the back of the saddle. The strings go all the way through the body. Being a fixed bridge makes all of that a much easier mechanical design.

    It will be fine. You will probably need to boost the output to line levels to get enough volume. If you have a good sound system it will sound great! I have done it with my previous pods.
  17. Charlie_Watt
    Make sure that they did not thread both sides. Maybe they did and you can move the screw.

    I had trouble downloading them with Windows Explorer but it worked fine with Google Chrome.

    If you are using the XLR out for recording, I would not plug in the USB cable.
  20. Charlie_Watt
    Don't know about you guys but I don't like bad language in these forums. Not necessary and serves no purpose.

    I run with my second input set to "aux" as it seems to be slightly quieter than Mic. Mic has more gain. Having second input set to "Same" will clip with a hot guitar input. I use my JTV VDI input so I set my input 1 to guitar and variax and input 2 to aux and I mad it global.
  22. Charlie_Watt
    For Acoustic Amp just use no amp and add effects. An acoustic is only going to sound good through full range speakers no matter what you put in the path.
  23. Charlie_Watt
    If you have a DVM measure the DC on your guitar cable (when the other end is plugged into your guitar with EMG pickups) You should not have any DC there. My guitars with EMG pickups (I have two) work fine with my pods. Their output is not all that much hotter than passives and there is zero noise pickup. That's why I use them. Much less noise pickup than my single coil pickups.

    The 300 guts are different than the ones shown in the above build. That was based on an original 500. That build was done many years ago if I recall correctly. You used to be able to get routing templates to do the 500 transplants and Warmouth did make a Variax body.
  25. Charlie_Watt
    Sounds like you have a bad connection. Make sure it isn't the power plug. If not it's something inside that is getting stressed when you push hard forward on the expression pedal.
