It can oonly run on battery power but i bought one of the dc connectors like wots on the back of any of the boss pedals for mains power tried wiring it up but with no success, any suggestions??

Heres the dc connector i bought to use on it.

I really like this pedal and now its useless coe the battery slot is disconnected and the mains power won't work on it!! Using a dc brick for power btw.

You may need to reverse the wires on your new DC connector. If + and - are reversed it won't work.

The DC jack you bought has a metal body - often that body will be electrically connected to one of the terminals - installing the jack into the pedal chassis electrically connects the body to the chassis.

Trouble is the input and output sockets are also made of metal, and are also installed in the pedal chassis, and are ultimately connected to ground.

If you connect a positive voltage to the wrong terminal of the DC jack, it gets shorted to ground via the input/output jacks and the pedal will never work.

So you need to be careful to connect the right voltage with the right polarity for the circuit, without inadvertently shorting it to ground via the other connectors. Most often we achieve this by using plastic DC jacks that isolate all the terminals from the pedal chassis.

+1 to niftydog. It's really easy to wire in a DC jack, but just as easy to screw it up (after all, you're working with just two wires - you either do it right or do it wrong and need to re-wire it). Plastic DC jacks are ideal to prevent shorts, as most pedals are center-pin-negative, with the barrel positive. If the metal barrel comes in contact with the metal chassis of the pedal (which is usually attached to the negative ground), you have a problem.

Also... if you'd rather not go through this hassle, just use a battery clip adapter with your DC Brick. IIRC, don't they actually come with at least one of those adapters?

Even if it doesn't, just buy one to attach on any of your Boss-style-barreled cables which came with your Brick. Diago, Visual Sound, Godlyke, and others make these adapters.

They're great until you need to disconnect them. Then they stop working. When I had a Russian Muff I broke two of them before I got wise and stopped trying to take them off the battery clip.

There was a company that modded them and added a power input thingy. NOt sure what its called though.
