    Electrovibe Chorus volume

    I know you didn't design the circuit but why would stock only let 68% through, I mean why would someone want a vol drop? is that how the original worked?

    RAT squeal

    So I have a squeal on my rat at higher gain that will go away if I touch anything in the input path up until IC pin #3. I have seen something about parasitic capacitance but I honestly don't understand that, its above my head. if it is going away when I touch it is it a grounding thing?

    Electrovibe Chorus volume

    so I may sound like an idiot here but which one is R4, I couldn't find a doc with the locations. I just know its 47k

    Electrovibe Chorus volume

    so this may not really be trouble shooting, I have never had a uni-vibe and maybe this is how they work but on vibrato volume is full just with the effected signal. on Chorus I also get the effect but at a pretty decent volume drop. I have messed with the trims inside and have the volume maxed...

    double pedal voltage

    ok so I thought that I had this sorted out. voltage is good now coming in now and the Mach-1 sounds great but something is off with the SSS. getting a volume drop unless the volume is pretty high and the "drive" just sounds plain bad. I measured the J201 and here is what I have for each at...

    Must have been a joint, checking them we are good now

    double pedal voltage

    good to know that 5.5 V is wrong, at least I know I have something going on here and can start tracking it down

    double pedal voltage

    I have a double pedal that I have built, its a Mach-1 and a Six String Stinger. They sound just off, esp the SSS. When I measure the voltage coming in I get about 5.5V. It is a good power supply, 9V. is this expected on a double pedal or do I have an issue?

    Electrovibe Mockup Pedal

    not sure about others but I printed out the picture of the PCB and went one by one writing down the components marking them off as I went

    Electrovibe Mockup Pedal

    so I really want to use the paddle switch, but no experience with square holes. any pointers here before I commit to ordering that faceplate?
