Wah Troubles

[Warheart]

Hi,
I've got a Vox 847 that has only been modifed for a true bypass, but I've been trying to connect a power supply without actually modifying it. It doesn't have an external one So far I've tried connecting a 9V battery clip to a 3.5 mm ac jack, and then connecting the two battery clips together (reversing the wiring to accomodate the clips), but it seems to cause a huge grounding issue. Should i just solder the 3.5 mm to the wires for the power supply anyways? I'm really at a loss. It seems that unless I use a battery, its gonna give me a huge hum and not even work.

Re: Wah Troubles

When you hook it up with the 9v wall wart it just totally doesn't work?

Re: Wah Troubles

first of all, does it work with just the battery??

maybe StratDeluxer can help - he bypassed mine, and added an adapter socket

Re: Wah Troubles

Your wah needs a specific power supply board built that has a resistance value,a cap,and a diode for protection....This board also offers a buffered power supply....Adding external power supplies is part of my wah mods and the jack is part of the mods also...

If the pedal doesn't work with just a battery,then you have other issues?

Re: Wah Troubles

No, the wah works with the battery, but it can only take batteries; there is no jack for a 9v power supply. I'm just trying to find a way to use a power supply without externally modifying the wah.
here's what i tried:
9 v wall wart --> 3.5mm ac jack (from The Source) --> soldered to a battery clip which then connects to the battery clip inside the wah.
but this gives a load of hum, even though the solder connections are good. maybe I could just add in a resistor, a cap and a diode?
What do you think?

Send it to me and I'll make a pro board that you'll never have problems with...Do it right!
