"Hi, I'm in Delaware."
I've got an older Vox wah pedal that doesn't have an adapter plug, which isn't so bad as long as I remember to unplug my guitar, but depending on which pedalboard I get, unplugging it all the time could be annoying. Is it possible to modify it so that I can plug it into my power supply instead of always using batteries? Thanks.
 
I went through something similar with my setup. I just put a toggle switch a 2k resistor and an LED in between the battery and the pedal so I don't have to unplug it all when I'm done.

the Godlyke power supply comes with some adaptors that go from your 9V power supply/daisy chain to the connection for a 9V battery -

how does that look?

Yeah, I was going to suggest something like that. But you should also consider that your pedal will be quiter if you are using a battery (the rectifier circuits used in wall warts are not very good, so some amount of 60 hz hum will frequently come through).

Wait, so if I hook up this power adapter doodad from Musician's Friend, you're saying I will get some hum coming through? Will it be a lot? Cuz I know that at least with my stompboxes this isn't a problem, but they are made to be plugged in.

(sorry my reply took so long, my notifications don't seem to be coming through...)

Also, as for the other option, are you saying you basically just put an on/off switch in the circuit? I imagine that with that, hum wouldn't be a problem, yes?
 
I have the godlyke, and while it will suffice for practicing, etc, I've still got a 9v battery box with toggles for all of my pedals that I use when recording. The muli-pedal power supplies, in my experience add a bit of hiss to the signal, maybe my wiring sucks, I don't know. In your instance though, a 9v battery, 5 cents worth of wires, a 50 cent resistor, a 2 dollar toggle switch and a 30 cent LED and you're good to go at the flip of a switch.
 
I don't know much of anything about wiring stuff... dont' suppose you have any diagrams as to how I would set that up?
 
It's in the post I linked. Just click on the picture, it should have the option to show it in a bigger size.


Basically you cut off the battery clip, either leave plenty of wire to reattach, or have a new battery clip available with plenty of wire on it.

Run the positive of the battery clip to the toggle switch, I used two wires on the other side of the toggle switch, one to the LED one to the pedal.

Splice the negative wire and run one to the other side of the LED and the other to the negative on the pedal.

Gravy!
 
Yeah, sorry, my reply got sent late. The illustrations are plenty clear. Thanks!
