total panic help!

Totally wigging. I bought a used pedal today. Totally crazy rare score. Wildy overpaid for it. A Boss Para EQ PQ-3B. The next gig is supposed to have a subwoofer. I thought it would be great to whoop it up and move some air.

Tested it in the store. It worked fine. 100%. I stomped it on and off and twisted every knob & it was all a go.

Took it home, pulled the velcro and cat hair off it, stuck a 9v in it. No go.

Tried my power regulator (both a one spot, T-rex Chameleon). No go.

Put the battery in another pedal, battery is fine as a sanity check. That 9v is fine. The other pedal honks as expected.

I honestly did nothing but carry it home, pull the velcro off, wipe it down, stick a battery in it and now it doesn't work. What the?!?

The dude I bought it off of is going to think I am playing some kind of game. I am at all loss.... Is there is something I am not checking?

Man, I have already been ripped off once this month (not a big deal but still...)

I have VERY limited funds to work with. I am swimming in medical bills since being diagnosed with cancer. Gear wise everything I touch just turns to p00p lately. I am swear I did NOTHING but pull the velcro off it and pull some cat hair off & stick a battery in it & nada. It is a Boss. I can't imagine what i did to it carrying it home on the subway in my bag or at home that killed this. I know this dude is just not going to give me my scratch back (very very painful purchase, i agonized over it for 2 days but my birthday is this week and I have 2 more gigs before they cut me open and some recordings).

Now I do't have the pedal or the $. and am totally not able to think straight and hyperventilating.

What do I check?

Did you have a guitar cable plugged into it when testing it at home? The unit won't turn on if there isn't a cable plugged into the INPUT side.

I did....

But I just noticed that the power-all does not seem to be working all of a sudden (hard to tell, too nervous to try again with a different pedal and zap that pedal too).

I am wondering if my power all is just bad and co-incidentally, so is the battery snap (I did try the battery first and in the store they had it hooked to a power brick)... I need perhaps to borrow my band mate's iso-regulated super power jibby or my t-rex again and see if it works with that.

Also possible, somehow plugging it in zapped it? (but then why did it not work when i initially tried it with a battery?)

ack. I hate this. buying pedals here in Korea is a disaster. everything is 4x the price, if you buy used you are rolling the dice, even name brands like Strymon don't back their products here (they want you to go back to the dealer, the dealer laughs at you).... I am too poor to be making these mistakes. Ack. What kills me is that I tested it. IT WORKED when I bought it and for once the dude I got it from is going to have a legit reason to not refund me. Besides it is Boss! You know lasts forever boss (okay i once had an Boss 8ve pedal die on me)

Deep breaths.... deep breaths...

This is what I get for spending money I shouldn't have spent. I hate myself right now. HATE.

I've had pedals where the battery didn't work, but the one spot did. I didn't bother to check it, but pull the bottom off and check the jacks. They are supposed to close a circuit to allow power to flow. A little dielectric spray will probably fix it.

I don't exactly the term in English, but i'll try… isn't it reverse polarity? Or something like rhis?

Tried a third power supply & jacks on input and same result. I bought it, stuck it in my bag, went home, wiped the dust an cat hair off it with a tissue, threw a 9v in it and that was all. How & why the heck did this die? It's a Boss Para EQ PQ-3B. Far as I can tell it has no special power concerns, just straight up c- 9v or dry cell which is just what I used. Used the battery first.

I think it takes a specific power supply.... you may have cooked it.

then again, you may just need the right power supply...

one thing worth trying... return to the scene of the demo and do exactly as you did... if it works, cool. if not, man.. I just saw one on ebay for 249... oof!

but then i wonder why did it not work with the battery? That's what I tried first. Buy it, use it, flip it for no loss has turned into throwing my money away. ack. person I bought it from is not answering me. Headed to a repair shop now to see if they can test it. dang.

and cause the gods are angry I tried to fly too close to the sun, the bill for my CT scan came today to mock me. heh. Hopefully I can get it fixed. Last pedal I had that broke just had a cold solder join and reflowing the solder fixed it. Maybe I'll get lucky.

+/-18db @ as low as 15Hz would have been brutalz.

probably just a broken wire...

place I bought from powered it with an Artec Power Brick SPB-8 from center neg. 9v tap.

it's in the pedal hospital now. I am in the waiting room.

fingers crossed.

oh baby. It lives to throb another day. The power tap was hosed and no longer connected to the board. A quick run a round with the meter and a new barrell soldered in an we have lift off. Makes this an expensive purchase but better than ending up with a paper weight and if I need to sell it I can probably still break even or close. woot. I am not crazy. it was actually broken and could have gone at any moment. it just choose to bite the dust after I got it.

beware next venue with a subwoofer. heh.
