I finally retired my poor old, worn out Dunlop Crybaby, and put a Vox wah on the board in it's place. Slightly different flavor, but way smoother sweep and easier to engage/disengage. One problem, though -- no AC power. Battery only. I effin hate batteries. I've gotten very used to not having to unplug my effects after playing, and as a result, I always forget. I had an aha moment when I realized I have a pigtail thingy that connects to a nine volt plug and into my powered pedalboard. Sweet! But alas, it doesn't work. When I plug in into the power strip, my whole chain goes dead. Shit!

Any ideas why this is happening? I thought it might be overloading the power supply's amperage rating, but even using it alone yields the same result.

Now I'm thinking I might cannibalize the Dunlop, wiring in the ac connector to the Vox. My fear, though, is that I go to the trouble to do the mod only to get the same result, since it seems essentially the same as plugging in the pigtail.

Help!

I'm nodding, Ken, I just don't have an answer. This is probably the most pointless response you're likely to get. Well, let's face it, it may be the ONLY response you're likely to get!

Possibly a reversed polarity problem with the pigtail?

Check the polarity of nine-volt snap powered up (NOT connected to the crybaby) with a multimeter. The large female snap should be positive, and the small male is negative. This is, of course, reverse from what you read on a battery.

No, my brain is not working again. It should be exactly the SAME as it is on the battery! Small male is positive, large female is negative. Forgive my attempts at burning up electronics.

I cam in late on this... but the pigtail you speak of... it's a 9 VDC adapter? why not get the pigtail to pin plug so you can use a power supply (that's what i did on my on Thomas Organ (original Cry Baby)... If I'm not mistake there are 9 VDC plug by female pin that switches polarity so it's correct for the PS

Thanks y'all! MDK and Lt were right -- I just taped the 9v contacts together opposite (big to big, small to small) and success! So I then cut the wire on the pigtail, flipped and resoldered it. Voila! Thanks for your help. Odd, though, that it was reversed in the first place...
