Please check your transformer. Is it Part No. 112053 Class 2? Input: 120vac 60Hz 15w. Output: 12vdc 500mA.

I left mine home last night, had to play without a volume pedal, not a good night. Must make sure I get the correct transformer, had a couple laying around my music room. Thanks in advance.

I regret hearing Larry had to play without a foot pedal. Years ago, I remember having to do that and it is no fun. Most devices are powered, which means musicians usually have several adapters. It would be easy to leave a adpater behind. Another problem is getting adapters mixed up, and plugged into the wrong device. I have protected against the wrong adapter being plugged in, and I think most manufacturers do. Here is what I would do; If it is a important job, it might be a good idea to have a spare pedal of some kind. I've had amps go out on the job, and thats one reason I always liked playing through two amps.
If you need a adapter for my pedal in a hurry, go to Radio Shack as they have a adapter that will work. Get a adapter that converts AC to 12volts DC. It must be at least 500mili-amps ,or greater, current rated. The tip size is 5.5 X 2.5 mili-meters. It will work with either a plus or minus tip. If you have a choice get a plus tip. Will a different voltage, different current rating, or even a AC to AC converter work?
A larger or smaller voltage DC adapter might work. I wouldn't use anything above 15 volts. You can use current ratings higher than 500 mili-amps. 500 mili-amps is equal to 1/2 amp. I have used adapters as low as 200 mili-amps, but sometimes they have problems providing enough power. The result is a on and off vibroto sound as the adapter trys to power up. Plugging in a AC to AC adapter won't hurt anything, but it will be noisy.
The best solution is to be prepared. Orgainze your adpaters. You can buy adapter plug in strips that lock the adapters in place. Wires run all over the stage are easy tripped over. Many people who use my pedal have ordered a spare 12volt adapter. Hope this helps!

Keith has come through again. Most vendors would have told you "only their" adapter will work properly.

There are many adapters available that will work but if you're not sure I'd recommend ordering one from Keith and then you'd be sure you got a compatible unit.

Thanks for asking about my pedal Bobby. The electronics draw between 60 and 70 mili-amps, which is a long way from 500 mili-amps. The current on start up is much greater than operating current. What causes the large draw of current on start up? Besides the AC to DC wall wart converter, there is a DC to DC converter inside the pedal on the circuit board. When it first charges up, the draw is between 300 and 350 mili-amps. You might ask why a DC to DC converter inside the pedal? Well Bobby, I have built my own little switching power supply inside the pedal for various functions. Computers and lots of things nowdays use switching power supplies. Last year I tried some 200 mili-amp wall warts, and many of them would swamp out. When the wall wart would swamp out, they would shut down then come back on. This created a great vibroto sound.
Strange this DC to DC converter came up, because I was just thinking about it. The converter I use is a Datel DC to DC converter. If you call up Datel, they want around $40.00 for them. I had a source out in California where I got them for around $8.00. I have 16 of these converters left and need to re-order. I notice that the price of the company in California has went up to $16.00. Every time I depend on one company for a particular part I run into trouble. I have been looking at different DC to DC manufacturers, to see if I can get a price I can live with.
