I thought I had a good deal a whyle back on a used Electro Harmonix Poly Chorus pedal.

The trouble is the more you turn up the Rate, the faster a weird clicking sound comes up.

Does any one have any idea what this could be, or what to do about it?

I am using the original, correct power supply.

(Voor eventuele Nederlanders hier, ik heb dus problemen met mijn reet :D)
 
Polychoruses are great little boxes with some very usable settings, but they've always had notorious clock noise at higher settings. Don't know if it's changed since they started housing them in the die cast chassis.

EHX stuff is always kind of a crapshoot.

That's normal? I don't understand this kind of stuff, my brother has that Big Muff pedal. Sounds great, appart from that wall of hum behind the effect which makes it unusable as far as I'm concerned.

Is there a mod to do something about this clock noise?

if you're talking about what i think you're talking about.....

It's possible that a trimpot alignment could help, but you need an oscilloscope, tone generator, a good schematic, and most importantly the know-how. You could potentially make it a lot worse if you don't know exactly what you're doing.

Or, if you're really bent on using the Polychorus at those settings, have Howard Davis fix it for you. He designed it.
