Title: Wiring problem on first MadBean Build
Post by: SGJarrod on September 30, 2010, 09:17:30 PM
So I just finished my first MadBean build. I did the MuddyBunny and it rocks.... But it does not work with a power supply..only a battery... I used the normal 9v dc jack from SmallBear and wired it center neg like I always do... When you plug in a cable from my Dunlop Power Brick it cuts of the battery but does not power the pedal... I just got done switching out the dc jack thinking it was defective but I got the same results.

I used the wiring on this link from General Guitar Gadgets...any advice or ideas?

Can you post a pic of the guts of your build? Maybe we can identify the problem that way.

Chances are it's a simple problem. It may be a faulty jack, or more likely, you've made a small mistake and it should be easy to fix. Tutorials for debugging are coming!!

Give us more info and someone should be able to help.

Have you perhaps got the battery's + lead on the wrong lug of the dc jack? Try swapping them around.
