    Hello Guys, new to the site here. Maybe you guys can help me out.
    I have a Graphic Fuzz that pops when ever I press the bypass switch. It’s not a small little pop at all. You would know when I would engage the Graphic Fuzz that I’m using it because of the loud pop when I engage the pedal. I’ve tried many different configurations with other pedals, different cables, plugging it in different places and just using the pedal by itself… and it still pops.
    Another problem I seem to be having is with the Dynamic function of the envelope. Its very inconsistent, and it has nothing to do with my attack. The overall level of the guitar fluctuates from being at the right level to having no level at all. This happens when I’m playing very hard, soft or in between This only happens when I use the dynamic slider in any position, in the off(all the way down) position the pedal works fine. It’s as if a ghost hand was turning the volume up and down at a slow and steady rate.
    Well thats about it, Any thoughts would be great! Thanks!

    For the popping, try engaging and disengaging the pedal several times before you start playing. That should help, if it doesn’t then I would say your switch is faulty. As for the Dynamics slider, where do you have the Sustain set? I’ve never experienced anything as dramatic as what you’re describing, but with the Sustain all the way down the pedal will very quickly kill your sustain (like a noise gate with the threshold set too high).

    If your switch doesn’t stop popping after a few clicks and your pedal does the same thing with the Sustain up anywhere above 50%, I would say that you got a lemon and should send it in for repairs unless the pedal is already out of warranty and you’re extremely experienced with pedal repairs.

    Even if the pedal is out of warranty, EHX is pretty cheap when it comes to repairs and the last thing you want to do with these ‘slider knob pedals’ is start messing around within the circuit, it’s a pretty awkward location to work in unless you start desoldering wires and then you wind up with a giant mess should you forget where any go…

    Believe me, 6 months ago I carefully photodocumented the entire process of me fixing a cold solder and rewiring the LED to a status indicator in my big box Micro Synth, and even with the photos showing every step I took, I’m STILL chasing around small little problems here and there.

    Thanks for the insight guys.
    Yeah the popping is pretty bad. I mean I have many True Bypass pedals and this is the first time I have encountered this loud pop. It just doesn’t sound right to me, I feel like its a faulty pedal… I don’t know.
    Then there’s this thing with the envelope function on this pedal… there must be a problem. I just don’t get how the overall level goes from no level at all to having full on level( It happens at a very slow rate, cool effect but don’t think it was meant for that). If I have the sustain and dynamic sliders down, the pedal is fine in terms of level. Anytime I raise the dynamic slider, that’s when the problem starts, and I don’t think the sustain slider is having much of an influence in whatever position I leave the slider.
    I’m not one to fix pedals, I don’t have that experience. So it might mean sending it in to EHX.
