EHX repair?

    Well, my Black Finger has bit the dust.

    A couple of months after I bought it, it started crackling from time to time, and then the footswitch stopped working. I assumed that the crackling was related to the bad footswitch, because it crackled when I clicked it.

    I put the pedal in a loop by itself on my loooper, and just left it on all of the time. As long as I didn't mess with the footswitch, it worked fine, so I just turned it on and off by using the Loooper to bypass it.

    At yesterdays gig, it started crackling pretty much all of the time, so I turned it off using the footswitch instead of bypassing the loop. I tried to use it on a couple of songs, but it was so noisy that I gave it up.

    Today, I pulled out my pedalboard, hooked it up, and the Black Finger is totally dead. No power.:(

    Could a bad footswitch cause this, or did I ruin the pedal by using it with a faulty switch?

    Who repairs these things? How much can I expect to pay for a repair?

    Thanks. I have ordered a Demeter Compulator to tide me over, but the BF is so cool and funky, I want to get it fixed and keep it, unless it costs almost as much as a new one.

    Maybe a faulty tube?

    I would think that if a tube were bad, that it would still power up. None of the LEDs light up or anything.

    Hmm, have you tried opening it and briefly checking for loose wires or broken solder joints? Maybe it's just the power input that's gone bad? But that shouldn't explain the crackling.

    I had problems with crackling and noise in my Marshall, due to a dry cap in the power section.

    Good luck! :)

    Did you buy it new and regisister it w/ EHX? it might still be under warranty..

    That does sound like you have a faulty switch. Likely you haven't ruined the pedal, just a spot or 2 of cold solder that crystallized and is making intermitten contact.

    To begin with, open it, and check basically, as allready said. It may be pretty simple.

    If it's more complicated, I don't know. There are many ways to repair pedals.

    You can post at http://www.diystompboxes.com/sboxforum to find someone near you who could have a more knowledgeable (does this word exists ??? If not, what is the right word ?) look.

    If you're closed to Lyon, France, I can do this for you ! :D

    is the glass part of the tubes touching the enclosure/box? perhaps when you step on the box it was flexing the entire case enough to budge the tubes around causing the crackling, then eventual failure.

    just a thought.

    my black finger gets hissy after it has been on for awhile. i can turn it off then back on and the hiss goes away, but comes back in a few minutes. i placed a BiComprosser on order but like you, i really like my black finger.

    Nope. Back when the unit first started crackling, I checked the tubes and they were not touching the enclosure. And I checked them Sunday when the crackling came back.

    I wouldn't mind some hiss, but mine never hissed except for extreme settings.

    Does anybody know if a bad switch will keep the unit from powering up at all?

    Why not. Some advanced switches cut the power supply, but it's quite rare, though.

    But it can, maybe, keep the led from lightning and the sound from passing through, which can make you believe the unit isn't powered.

    Some basics tests would be more instructive. Do you own a multimeter ? If yes, check inside if the power points are powered, if the switch is really broken or not, and so on. If you don't have one, well, buy one !! It would cost about 20 dollars and it's allways usefull, for us who use electricity everywhere, for music.
