Dunlop Crybaby 105Q problem

a problem ive had with my dunlop crybaby 105Q, is that it doesnt seem to want to use a standard 9V adaptor, and only wants to take batteries. batteries seem to last between a few days and a week, usually the wah becomes less pronounced within that time period, then dies about 2 weeks after the last battery. ive placed in a 1100 mA daisy chain sequence, and the the combined mA consumption of my other pedals is about 600 mA. i dont know whats wrong, maybe i need to buy a proper dunlop adaptor?

ive tried playing it without a battery in the chain, it still will send my line to the amp, but without a battery, it looses all wah it can have.

Do you mean it physically does not want to use a standard 9 V adapter?

As for battery life...Do you unplug from the input after each use or leave it plugged in until next use?

The pedal does not take effect until the input is in. With that being said, when the input is in, there is a small amount of battery drain that is different from pedal to pedal. Some are pretty good about this and others will drain the **** out of the batteries. Unplug the inputs when you are done jamming or whatnot...

Make sure that the adapter you are using is the right type. Some pedals take - center + center ect... Also make sure the size is correct. Your wah should tell you the type of adapter to use like for instance 2.1mm center negative 5mm long. Sometimes they can be slightly different and that may be your problem. Good luck

Hi Aussie!

I've had my 105Q for 10 years - never had a problem with it not taking 9v power.

Just give it a 9v source.
- 2.1mm plug
- negative tip (just like a boss pedal)
And it should be no worries.
BTW - the current draw should be less than 65mA, cos thats all a battery can give! So 1100mA is plenty.

If you're still having problems, what other pedals are you using?

And yeah - unlpug the input jack when not in use (if you want the battery to survive)

Position on the daisy chain shouldn't have any impact at all. The connectors in a daisy chain are all wired in parallel, and whether you use the first or the last connector shouldn't make a lick of difference. Unless of course there's a fault with your daisy chain.

Which power supply are you using? Perhaps we can improve that for you. A good quality, regulated and filtered power supply is an absolute must. There's absolutely no need to buy a Dunlop brand power adapter - there's is NO benefit to that whatsoever.

Regarding the fresh battery "oomph" factor - a fresh battery might actually output 9.5V for the first few minutes of use, but soon after it's installed it will start dropping off. While the power supply might not have as much oomph as a new battery, it will maintain what it has indefinitely, unlike a battery.

sorry, but ive come back. the pedal DOES NOT want to work with a 9V adaptor. ive tried with a battery, without a battery, and cranking the volume. nothing. it only wants to work with a battery.

i tried it in a daisy chain with an excess of 500 mA. it fits in the power input socket, but its not giving the pedal any power.

im allready starting to jump to conclusions like the wiring inside the pedal is broken.....

ok, i tried putting it first in the daisy chain series, and it worked alot better.

Ok, now I'm officially confused - does it work or doesn't it? And define "working" for us because I'm lost! :eyebrow:

What type of power supply you're using? Has the polarity of the connector has been checked. Does the power supply work with other pedals?
 
#17
the pedal works, but using an adaptor does not work. the polarities are correct, the adaptor works with other pedals of the same polarity. ive tried different positions on the daisy chain, those dont work with the wah pedal, but work wiht my other pedals which have the same polarity.

"working" - an objects ability to perform the way in which it is ment to work. ie: my pedal does not function with a 9V power supply from a 9V adaptor, but it does work when i place a battery inside it.

Right, thanks for clearing that up. You've gotta be particular about what you say, what you don't say, and most importantly, HOW you say it around here or else people get misled or discouraged very quickly and easily.

Now, I don't have one of these pedals, but I'm almost certain that the power jack is directly attached (soldered) to the PCB - so there's no wiring to break off. There's three likely scenarios:

1. power supply connector is the wrong size or is dirty.
2. power jack is dirty or deformed and not making good contact.
3. power protection circuit has been damaged.

So, I imagine you have tried jiggling and rotating the connector to see if it has any affect? Take a good look inside the connectors on the wah and on the power supply (use a torch) and make sure the contacts are shiny and metallic and that there are no foreign objects. Also, compare it to other connectors to make sure the contacts aren't bent out of position or a different size.

The third problem will require you to open up the wah and get familiar with a multimeter. This may mean more than just popping the back off - you might have to do more disassembly to get at the components on the circuit board. Let me know if you want to go down this path - you might want to post some pictures if we get to that point.

i'm a guitarist, but i'm having a problem that sounds very similar..

i have had my crybaby for around 15 years, i used to use it with a battery and always had intermittent problems where it would not turn on. But i eventually started using a power pack, and it has never been a problem until recently.

Basically, i removed the screws that normally hold the base on and fitted longer ones so the pedal is fixed to my pedal board however the pedal's correct base is still fitted to the pedal before it is mounted in the pedal board. it has been like this for a number of years and never missed a beat. recently though it started intermitently not switching on, so i removed it from the pedal board to investigate and found a cracked solder joint where one of the powerpacks terminal is connected to the pcb, so i resoldered that joint and tried the pedal out without the base fitted and not in the pedal board - worked fine... put the base back on and refitted to the board, went to a gig, turned it on and got nothing, but when the pedal switched off the signal passes through as it should...

now i could be wrong, and hopefully someone here might be able to suggest a solution, but i think it could be the terminals that connect to a battery shorting out on the base plate?????

would this make sense???

btw, i'm also in Aussie..
