Introduction: DIY Custom Rock Band Pedal, Just Like the Destroyer Pedal!!!

This instructable will show you how to put together your own custom Rock Band pedal, just like the Destroyer Pedal, except you won't have to pay $70 for it!

I decided to do this because I didn't want to buy something that I know I can make myself, and since I'm an engineer I love building stuff. Oh, and the Destroyer Pedal is the biggest ripoff I've ever seen, $70 for something that only cost me $25 to build seems a little overrated, that guy is making a large profit, don't listen to him when he says he isn't, he just wants you to buy his product.

Well, enough with my whiny, cry baby opinion, lets get on with the show!

***UPDATE: I'm going to add how to make your own bass pad type thing for it, its way easier to do the quicker and also longer speedy sequences if the beater meets some resistence. I'll work on it tomorrow and monday and post what i come up with.

Step 1: Gather the Goods!

Here's the BoM (Bill of Materials):
1 x Bass pedal - I got mine off ebay, $14.50 including shipping, here's a link to all listed pedals.

1 x Reed Switch/Relay - i got mine from Radio Shack, you don't really need a reed relay, because you will be using a magnet to trigger it, but Radio Shack only had the relay type and thats what i got. either way, they work the same in this application, fyi jameco has some cheap ones, just make sure that wherever you get it from you get a NO(normally open) type, not NC(normally closed). MAKE SURE YOU PAY ATTENTION TO THIS!!!

1 x Magnet(12 mm x 12 mm x 5mm is recommended) - I recommend getting a rare earth magnet, particularly a Neodymium magnet. I got a 'grab bag' of these once from a website for really cheap, so i have all different kinds. Sorry, but i forgot the site, or i would post a link. Hereis a link to a good site though.

1 x 1/8 inch ""mono"" jack - I got mine from Radio Shack, and it came with prestripped wires so all i had to do was solder them to the leads from the reed switch.

*Optional* 1 x Soldering Iron/Solder - It makes a better, stronger connection, but isn't absolutely necessary.

Step 2: Reed Switch/Mono Jack Assembly

Connect one of the leads from the mono jack wire to one of the leads on the ends of the reed switch, either using solder or twisting them together or something. Then, connect the remaining wire to the other lead on the reed switch. If you want, you can use some electrical or duct tape to tape the switch to the cord to make sure it won't get wiggled around. Ta Da! That's all for this, but just to be safe I've included a diagram...

Step 3: Attach Switch Assembly to Pedal

Attach the Switch assembly to one of the support posts on the pedal, I chose the left side, since I'm planning on using this as my main pedal for my right foot, and i want the cord to be out of the way.

I used three small zip ties that you can get almost anywhere, i got two packs of these from radio shack last summer for about $2 each. Make 2 of the zip ties into loops, and then wrap the third around the pedal post and then through those two zip ties. then, just put the reed switch inside them and tighten them up and there ya go, its attached! See the picture for a better idea of what i mean...
(sorry for the fuzziness, i didn't notice it when i took the picture)

***UPDATE***
I changed the reed switch to the bottom of my pedal, its now zip tied to the rectangular metal thingy down there, and magnet was moved to under the pedal, it now works much better, and double bass is easier. ill post pics as soon as i can...

Step 4: Attach Magnet to Foot Plate

Get your magnet, Neodymium or otherwise, and a large zip tie, or some glue, etc. Then, just wrap the zip tie around the pedal and put the magnet inside it on the side of the pedal where the reed switch is attached and tighten. If using glue, or tape, or whatever, then just attach it that way, as long as its on the side with the reed switch.

Step 5: Test It!

This is the slightly tricky part, because depending on your pedal, this will vary for everyone, but the concept is simple: Make magnet close to switch. I suggest sitting in a chair and pressing the pedal while the game is in practice mode. Be sure to do normal kicks, nothing too outrageous, just like you normally do. If it doesn't register, never fear, you probably just need to move the magnet closer to the switch, or move switch closer to magnet, etc. Once you figure out the magic position, go to the next step.

Step 6: *Optional* Double Bass Mod

You can go to Radio Shack and get something like THIS to plug in both bass pedals at once. There's only one problem with this: If one pedal is pressed down, then the other one won't work until you let off of the depressed one. There is an easy way to fix this, well actually, depending on how good you are at soldering/electrical circuit assembly, it might be quite hard...but anyways, go HERE to find out about it. If you go this route, then you don't need the Y-Adapter above, because you will be using two mono in jacks in the circuit.

Thanks for reading my instructable! Comments are appreciated...Please rate if you like it!
(sorry about the lack of good pics, i didn't think of making an instructable when i actually made the pedal yesterday, so i only have completed photos)

here are all my pictures of my completed bass pedal

I live in Australia and was having trouble finding materials, but then I realized my old bass pedal had the stuff I needed! Thanks so much, my old pedal breaking just improved my drumming!

Looks like a fun project to try! I was wondering if you made the bass pad yet?

hock3ydud3 (author)mahzilla2008-07-19

no, I've been busy with work and school and it kinda slipped my mindbut ill try to see what I can come up with this weekend or next and I'll add it in when I do

i actually did make the bass pad, i used a remo practice pad and added a piezo sensor wired to the same type of wire leads and just added a beater to the current pedal so i could use it for ghwt.

Muchas grácias por la informacion camarada!

Tu trabajo se ve que tomo tiempo y es muy util para los que todavia tenemos la bateria de Rock Band. Éxito en tus proyectos futuros.

Hi.

I've tried to do it but used switch without coil ( like this one http://www.chipdip.ru/product/kem2-b.aspx ). So actully this didnt work. After making some tests with ohmmetter and voltmeter and comparing with original pedal, i've realised that actually original pedal not only switching the curcuit but generate a splash of voltage (actually as peuzo sensor works - under pressure it generates some volts). So most probably your pedal works because you wired the "external" coil connectors of your relay so it generated the splash of voltage when the magnet passing by (because of appearing current with changing of magnet field in coil). Will try it later on actual relay. Can you check the connectors which you wired your relay please)

hehe the beatles' rockband is coming up with a bass drum cover so this will be cool.

Cooshinator (author)2009-01-26

I was wondering, could I wire up a mono headphone jack to a peizio sensor? Or do I have to stick to the mangnet and reed switch? I was thinking about making a bass drum pad so i could use a normal bass drum (& possibly a double bass). And if it wont work, is there any other way i could do it?

Aside from all aesthetic values, what is the purpose of having a pedal like this? Is it easier to play faster or anything, or is it just purely for having a realistic pedal?

author
Bulletbill (author)asylum1012008-10-07

Yeah, it makes it easier to do fast pedals. It is almost essential to use this type of pedal for expert songs.

author
asylum101 (author)Bulletbill2008-10-07

Mmm, I was suspecting(and hoping) this would be an ulterior reason for this. I recently broke my pedal and fixed it myself with a piece of wood I found in my house, but it's tough to do faster beats, so I looked on here. I may give this a shot sometime soon.

You mention adding the bass pad...

I made one out of that foam project board...I'd gone about solving the problem a little differently, putting the switch in the bass pad and the magnet in the head, instead of putting them in the pedal.

I like the way you solved the problem...seems less likely to eventually break (either the magnet or the switch). Tho you've pre-solved any future breakage problem with the replacement reed switch...

Perhaps I'll modify my build this weekend, put my switch & magnet in the pedal, but leave the foam board assembly for my strike pad...

Thanks so much! This was really easy with the reed relay/switch 2750232, 1/8 miniplug/stripped 4202434 (comes with the perfect length of wire attached and already stripped), a magnet, and my sons old drum pedal. About $9 for the parts. Works perfectly.

My man I really appreciate the step by step pedal assembly for rockband, cause I was about to buy one from ole boy. My pedal works great! Thank you!!!!!!!!!!

author
Rishnai (author)2008-04-16

So THAT'S how the rockband pedal works. I feel like an idiot now. I've been meaning to put together an actual drum pedal to use instead of the incredibly pathetic pedal it comes with. Now I need to go do this, thanks! Finally, not failing Tom Sawyer because of the pedal not working like a real one.

detritus (author)2008-04-13

This is really awesome. Nice job. I've been looking for a method to create my own pedal, so this is perfect. What size magnet would you recommend using on the pedal?

author
hock3ydud3 (author)detritus2008-04-14

i used a 12 mm x 12 mm x 5 mm square, so something in that range. just dont go too overboard in size, because larger magnet = larger magnetic field, and while that may sound good, if you are trying to do double bass with just this pedal by itself, you want a small magnetic field so that you dont have to let up as far between kicks

drummonkey92 (author)2008-04-13

nice job. i havn't got rock band (way too expensive at the moment0 but i play drums in a band n the thing with rubber bands is a great idea...def gona chuck sum bands into my gig bag with the duct tape for repairs lol although most(if not all) pedals can be adjusted anyway with some nuts at the bottom of the springs

author
hock3ydud3 (author)drummonkey922008-04-13

yeah, but the pedal i got didn't come with springs lol, so i used rubber bands instead of buying some springs

author
drummonkey92 (author)hock3ydud32008-04-14

ye like i said, brilliant idea i just wrote that coz in you'r ible i think you said that you thought they were better than springs coz you could adjust the tension

frazeeg (author)2008-04-13

If you've got a digital camera, it probably has a "macro" mode for taking up-close pictures like these. It's the setting that has a flower on it. That way you can make crystal closeups :-)

author
hock3ydud3 (author)frazeeg2008-04-13

lol, thanks for the info, my camera has that mode, but i never new what it was for...

How long did it take to build?

author

not too long, once i had all the parts it took maybe 30 mins, and only cuz i had to heat up my soldering iron lol
