Switch pop

[Luke Drifter]

I've got a lovely pre-LED Voodoo Lab Chorus (a CE-1 clone I believe) which sounds great and works great, except

for a switch pop everytime I turn it off or on

I've tried it with with different amps, and Im pretty confident its not DC leakage from any amps input

I've switched in on/off/on/off/on/off to try and make the pop go away but that doesn't
work

Does anyone have any tips for me to determine whats wrong with it before i go and spend 100 bucks on it (what it costs to get a pedal even opened by a tech these days)

Its probably worth spending 100 bucks on, as its a really nice (and rare) pedal, but if all it needs is a $1.50 resistor it would be nice to know that before I do. I'm handy with a multimeter, but not with a soldering iron

Is it true bypass? Some of those pop more than Orville Redenbacher.

[Luke Drifter]

supposedly, yes true bypass

but some pedals (T-Rex) describe themselves as TB, but are not exactly, they have some funny circuit thing in there

I somehow always imagined VL were the same, but i wouldnt know. The blurbs say true bypass

Found this. So not 3PDT.

Pop could be from a messed up opto-coupler?

Thanks for that Laurie - I will study it. It is a very old (pre-LED) version
(doesnt have "Made in the USA" stamped on the front of it)

I might have to try a battery in it (I have had it on a Cioks power supply, and a wall wart)

quote: "I bought and sold this pedal 3 times. I can't live without it. In some instances it will have an apparent volume jump. Can be annoyting and rig dependant. It certainly has a phasey chorus thing going on. In the vein of a CE-1 (which I have). Can also be noisy and chirpy. Use a dedicated powersupply or battery. chirps in a power daisy chain. It will have white noise on top but for me its liveable. Get one. They are cheap."

Same deal with the battery. Its not so much a "pop" as it is like the sound of a stylus dropping onto a record and finding its groove, more of a click
