A real kick pedal could be converted into a Rock Band kick pedal with just a little bit of effort and without ruining the pedal for real life use.

I'm a beginning RB drummer whose kick pedal is working fine so I haven't had the motivation to try this yet, but I've seen quite a few threads about broken pedals so I thought I'd post this solution for anyone who would like to give it a try.

If you have any kind of experience with rigging up electronics this should be a simple doable project.

Cost:
Free if you're willing to pillage your existing Rock Band pedal and already own a real pedal
Less than $10 if you prefer to keep your warranty in tact.
If your don't have a pedal already add the cost of one plus $10.

Theory of Operation:
If you've examined the RB kick pedal you've probably noticed that there isn't any visible switch. This is because a magnetic reed switch is used. A reed switch is two thin strips of metal inside a small sealed tube. If you look at the tip of the pedal you'll notice a small magnet on the underside. When the magnet gets close enough to the reed switch the magnetic field causes the the two strips of metal to touch closing the circuit and signalling a pedal hit.

The beauty of this is two fold. For the builders its cheap and reliable, there's no switch to get worn out as there is with the guitar. For us it means there no complicated signals going back and forth between the kick pedal making it easy to copy.

The jack on the back of the Rock Band drumset simply puts out a small voltage on one output wire and looks at the returning input wire to see if the reed switch is opened or closed. We'll be recreating the exact set-up used in the original pedal.

Skills need:
-Resourcfullness
-Ability to do basic soldering
-Multi-meter operation
-Basic mechanical skills

Supplies:
-Real Kick Pedal (if you're a drummer you probably have one already)
-Reed Switch
(This is where resourcfullness come in. Radio Shack's website lists them at $2.99, I'm
unsure if they stock them in store. If not, search around for local places that sell
electronic components. They should carry them. If you absolutley can't find them use
digikey.com or mouser.com to order one)
-Cord with mono jack.
(Radio shack will carry this one. Though it will likely have somthing on the other end
that you'll have to cut off and throw away.)
-Magnet, Small and strong.

Building:
If you've understood the post up until now you likely already know what to do.

-Strip the wire coming from the jack so that you have two exposed wires, making sure its
long enough to reach the pedal on the floor.
-Solder or otherwise attach each wire to each end (pole) of the reed switch.
-Tape or glue the magnet to the tip of your kick pedal

Now you'll need to experiment a little bit with how far the switch needs to be for the magnet to set it off. Try using practice mode and a song like Dead or Alive and slowing it all the way down. Once you've determinded the correct distance mount the reed switch anyway you see fit. Make it removable if you want to continue to use the pedal on your real drum kit.

Viola! You can now use your real pedal for Rock Band!

If your interested in doing this, post and let me know.

If anyone has idea's for improvements please post them. I'll try and answer any reasonable questions asked.

sounds like an awesome idea to me. I'd like to add this idea. If I do this I'll definately get a practice kick pad to attach the pedal to so the beater has something to hit. It needs bounceback to feel right. It will also keep the pedal from being wobbly. Then I would adjust the switch to activate at the point where the beater hits the practice pad.

Nice post. Thanks.

Yes, I had seen that solution. It is partially what inspired my post. I think the reed switch solution will be more reliable and elegant in the long run. Not to mention a little easier to do.
It may feel odd to have the pedal stomping down on a wooden block as opposed to it's normal stopping point. With the read switch you also don't have to worry about making a block and getting the size just right.

I just thought of the perfect idea. Take a real bass pedal and practice pad like before. Take the long mono wire and leave it together at the input of the drum controller but near the end seperate the wires. Put a piece of metal on the practice pad where the beater will hit. Attach one end of the wire to that piece of metal. Then run the other wire up the underside of the footpedal, up the arm, and to the middle of the beater. Then every time the beater hits the practice pad, it will complete the circuit and a hit will be registered. One of the flat beaters will be best for this. I can't wait until I or someone else tries this!

Or you could embed a magnet into the beater and mount the reed switch directly behind the practice pad. I'm not sure how close the magnet needs to be to the switch, but most practice pads aren't any more than an inch thick. If you have metal on the beater physically mating with metal on the pad, durability becomes a problem.

Or you could just keep the magnet and switch where they are and use the beater for rebound only.

That works too. Hopefully the vibration from the beater hitting the pad wouldn't disrupt it, causing a double hit. We could always just embed a switch into the beater so that activates when hitting the pad. We would have to have a durable switch for that though. I would think the switch would eventually break. We are definately onto something though. I just don't think using anything magnetic with a real bass pedal will work very well. I could be wrong though.

The magnetic switch works great in the bass pedal that comes with Rock Band. Its one of the few things that no one is complaining about breaking or having problems with. They are very reliable.

I also did consider the switch behind a practice pad, but suggested the 'on the pedal' method because of the noise issue. I was also worried you might get a double hit from the bounce of the beater on the pad. Additionally the other solution doesn't require you to have a practice pad.

Experiment though, people are looking for results. The important thing is that it should be an easy issue to solve, there is no complex signaling taking place. Any switch that you can make work in a consitent way will fill the bill.

I wasn't talking about the magnet in the Rock Band pedal. That does work great and it is designed to work with a magnet. I'm very pleased with it. I was saying that I don't like the idea of using the magnet with a "real" bass pedal. Although your idea of designing it in the same fashion as the Rock Band pedal would work. I see nothing wrong with that. I just had some ideas that snowballed. Basically if I was using a real pedal I would want the beater attached for the weight of it swinging and for the realistic feel. If using a beater, it needs something to hit. Since i would want a practice pad I started thinking of ways to use the pad. I know we could just use the pad to stop the beater and go with the magnet idea. I was just trying to think of a better way than using a magnet. I know it works for the Rock Band pedal, but it's designed to work that way and its plastic. I'm just thinking a real pedal is capable of something better.

If you wanted to be really awsome couldent you figure a way to make it so when you hit the cymble on a real drum set you hit it in the game. it would be a pain and make your drums sound like **** but it would make it possible to teach real drums on fake drums lol.

at leat put a Bass infront of that real pedal lol it wouldl ook awsome
