SO when I switch off my ocd the blue LED blinks once about second later.... not every time, but quite often.

I had for a few years but only noticed this in the last month or so. I also power it via 18v Diago adaptor

Is this normal ? or is my pedal dying ? Reason ?

Everything else is working normally....

cheers

Have you tried it with a different adaptor or a battery?

Is it the tap tempo model?

Erm, no TT

I've tried without 9>18v conversion adaptor, same.... will try with batteries now.

Might email Mike Fuller.... I heard he isn't very good with aftercare though.

Would a video help ?

I reckon* that it's a capacitor discharging and nothing to worry about at all.





* based on no scientific knowledge whatsoever

Well for the short time I had the battery in it no blink...

Still the same with the power supply, after every 5-6 clicks on-off.

I dunno what bypass method he uses, but if it's Millenium based Tim Tim might be able to help you.

if it's a regular true bypass arrangement then when the pedal is off the path from the LED to ground should be broken so the LED being lit should be impossible.

Electrical current needs to flow from 9V to GND via the LED for it to light (electrons in the other way but whatevs).

DOn't know if this help but there's some blurb wank here about the OCD in particular:

I Have Lots of Questions about the OCD

Q: The OCD has the brightest LED I've ever seen, it lights up my entire pedalboard, but there is NO POPPING sound like on my other booteek effects...is the OCD true bypass?

A: Yes it is true bypass, and thanks for noticing the "no pop thing." I invented an active anti-pop circuit (not simply resistors to ground that eliminates almost all the snap, thump, and pop you're used to getting at higher volumes with true bypass pedals.

Q: The OCD is huge sounding, wide open sounding, why does it make my other Overdrives sound like there's a blanket over the speakers in comparison?

A: Because 99% of all pedals use clipping diodes to achieve their distortion, and the net result is you are lopping off the upper frequencies (harmonics) and most of the lower frequencies, leaving mostly only Midrange.

Q: You're right, but why don't I hear it with other overdrives?

A: Because your overdrives filter out (Lop off ) the upper harmonics, the upper frequencies, and mask your amp's fizziness. Just turn down the OCD"s Tone control, which only affects those upper frequencies....or better yet, fix the amp.

Q: Is it ok to run the OCD higher than 9 volts?

A: Yes, you can run 9volts DC, 12volts DC, up to 18 volts DC, just make sure that the Center Pin of the adapter is "Negative." BTW, you can't hurt the OCD by using the wrong adapter because it has special protective circuitry...if you use the wrong adapter it just won't work or it will hum, but you can't hurt it.

BTW: Thanks for the help everyone.

I've also sent Fulltone a message so we'll see what they say.
