Why would a pedal suddenly not like to be daisy-chained???

    After years of good use, out of the blue...makes all kinds of low volume crazy noise when not engaged (ticking, whooshing...it's a chorus pedal) unless it's on battery or isolated. :confused:

    Thanks for any insight.

    What pedals are in the signal chain besides the chorus? Any new additions?

    are the pots dirty? corrosion/ oxydization can cause this anaomally,

    Maybe. I will give them a good dousing. But, they're not currently scratchy.

    also may be clean the contacts of the power input as well and supply as well

    I have 3 pedals that sound great on their own wallwart but noisey up to unusable if I put them on a multi power block , it could be a current draw thing , I dont know , as a course of action check the power supply or wallwart to see if it is an issue , what about the battery , does it do the same thing with a battery?

    Does it have power supply bypass caps? Are they leaking?

    Don't know. That's a bit above my paygrade.

    But, if they were, wouldn't the problem exist both if the pedal was being run in a chain or isolated? Currently, the problem only exists when daisy-chained, fine when isolated.

    If your power supply has good filtering, you probably won't notice any difference. The pedals filter should take care of it, so long as it is working.
    Sometimes chorus pedals start to tick when they get old due to poor internal filtering of the clock.

    Thanks. Don't know if it sheds any light, or not, but the the noises change when the SPEED knob is turned, even when the effect is not engaged.

    Maybe it's just time to put this one out to pasture.

    What about the wall socket? Could there be an issue there?

    Maybe, but the power is pretty clean here. And, it used to be fine on the same outlet (I have also confirmed that it is wired correctly).

    Sounds like the clock filter. A good tech can fix that.

    Tried swapping the power supply or using battery?

    Eliminate/swap each bit

    I would first be suspicious of a ground connection, then maybe a bad pot or switch, after that maybe a cap headed to that big components warehouse in the sky.

    Yeah, something wrong with the power supply plug on the pedal.

    Is there a 20 year old battery still in there and you've been running it on a wall wart for 20 years?

    It sounds like the bypass switching in this series of pedals (which would include the Vibratrem and Guv'nor 2) was prone to issues, and no, they don't have true bypass.

    So my best guess is that something has malfunctioned within the electronic switching itself, and when the pedal shares power with others, it's screwing up the switching so that it doesn't completely fully bypass. It uses a CD4066 CMOS switching chip that has four electronic switches in conjunction with the mechanical DPDT (basically two switches in one) switch.

    The pedals haven't changed, but what about your power supply?

    It hasn't changed. It's still the same supply that came with the BOSS board.

    I'm starting to suspect it's my house. I played away from the house last weekend but only had it going on isolated power. Forgot to try it daisy chained while I was out. :confused: Need to remember to do that next time, I guess.
