did my big muff just die?

[Aenima]

Hey guys i bought a Big Muff pi a couple months ago, well its sit around for a little bit with no use. Well today i decide to plug it in to practice a riff in one of my bands new songs and i get nothing at all through it,(i should mention that this is only when i click it on that i get nothing through the amp no noise or anything, however when i click it of i get my basses clean tone just fine out of my amp), i checked to make sure i had the cables in the right places, brand new battery, hell i even opened it up to make sure all the connections were soldered. I'm fresh out ideas so im turning to you TB any advice on this problem?

Which version Big Muff? Black Russian? American reissue?

The Black Russian has the input/outputs switched (common complaint).

Have you ever tried it before or is this the very first time?

[Aenima]

It is the Bigg muff Pi, (NYC model) it did try to switch the imputs but that didnt work for me.

So.......has it ever worked???

Check your battery....

check the diode next to 9-volt input. If it's not good (no current flow in either direction), then just switch it out with a 1N4001 (common and available at RadioShack). What the diode does is rectify the incoming signal from the power supply, which isn't a perfect flat DC wave, rather a "humped" wave (kinda like this: ^-^-^-^-^) when the diode is done with it, it looks like this: --------. pure, flat DC.

yeah, i havent played with it for about a month and a half (i began to like my clean tone alot more, and i had only used it on 1 song which we dont even play anymore...) now that we have another song that would be perfect for it i picked it up again to noodle around with it and thats when i ran into this problem


kaputsport: Thats the first thing i did i have tried 3 different batteries all that i had bought new



Thunderscreech: thanks, i will check it out, is there any set kinda easy way to check if there is any power flowing?

Yes. A digital multi-meter (they can be had cheap at Radio Shack) set in the diode (or continuity) mode. make sure you find the little line on the diode, whichever end it's closest too is where the current goes OUT (they're like check valves, current only flows one way). If the meter beeps/shows current flow, then it's not the diode. If it doesn't, you know the drill.

im so suprised another EHX pedal died...

or not.

That's really strange. I've got a NYC BMP as well, and never ran into this problem. Mine has even survived a rehousing into a smaller enclosure and a boss-style 9vdc adapter retrofit. Have you tried running it off an adapter?

[rratajski]

Meh, I heard the Bass Big Muff is better anyway. EHX is sending out telekinetic vibes destroying non-BBMs worldwide so people will buy the new BBM. True story...
haha

Good call on the adaptor! Let us know, Aemina.

Good thing that my BMP has a different housing. They must be overlooking mine as a replica or imposter.

My nyc big mUff did the same thing. Nice advice on the diode. Now I just haveta make time to test it. thanks
