DIY Wireless Mic to Wireless Guitar System





Introduction: DIY Wireless Mic to Wireless Guitar System

Ive been watching some vids and some bands and almost of them use a wireless system on guitar. Going crazy, moving, walking and do whatever they want without the cord so I dream of having one.. But.. for me now its too expensive so I came up to this idea.

an old wireless microphone to wireless guitar system.

Things Needed:

-a wireless microphone that send radio signals to FM or a wireless microphone with the receiver(the wireless mic to FM is the one I used in this project)..
-1/4" audio jack
-a case or small plastic box. (any kind that will fit for you)

Step 1: Disassemble the Mic.

Disassemble the mic. (Be careful of the wires and the circuits).
We will just need the parts inside of the mic.
We don't need the body of it.
we can also use the part of the battery case. I cut the part of the mic to have a battery case(As you can see in the photo).

you can also disassemble it without removing the wire from the battery..

The blue and the yellow wire i think will be the antenna of it. not sure but dont cut it..

Step 2: Remove the Mic Part and Replace It With the Audio Jack..

we don't need the mic. We will replace this with our 1/4" audio jack. just remember the wires that we remove for this.

Step 3: Assembling

find a case or a small box that will fit our project(I use an adapter case of our old printer).

Arranged it for better use. We will also use the on/off button or the signal light for battery purposes.

Step 4:

set up your FM radio and find the frequency of our wireless project and then set the output of the radio to the amp or other devices.

Lets Jam and Have Fun! _


-for some wireless microphone, they have their own receiver so you wont be needing the FM radio. I just give the idea on how to connect the jack in our microphone and arranged it.. _

-arrange the antenna wire to have a better range.

    Any suggestion on increasing battery life to atleast an hour or charging with a powerbank somehow while playing.
    This would be very helpful.

    i only used, SHURE wireless microphone the i convert mic to PL then, BOOM i have my own wireless system.

    meaning use a MP3 as a receiver?

    I finally finished mine, but have run into one final problem; range. I can barely walk about 5 feet away from my amp and it doesn't connect anymore. It depends in which direction though, so I'm guessing its either the antenna on the receiver, or the antenna on the transmitter, but i don't see an antenna on the circuit board. I'm thinking its this round gold-ish colored flat ring that is soldered at the end of the circuit board, but i don't know what to do. Any suggestions on how to increase the range? It also depends on the direction i am standing from the amp/receiver.

    Doing this project, I've run into one minor inconvenience; I don't know if this is standard with all wireless microphones who come with a receiver, but the circuit board is a little longer, thus needing more space than the one you used. Its at least 3 times the length of a 9v battery, so it'll take a bigger box, although now that i think about it, maybe i can leave an empty space next to the circuit board, and use it to plug in more batteries with some kind of battery hack. I'm almost done with this project, all that is left to do is to solder a battery holder(The thing that clips onto a 9v battery, whatever its called) onto the circuit board, since the microphone i bought didn't have one, it consisted of a metal plate, and a screw-on plastic cap at the end of the microphone held it in place, so i have to solder a battery clip onto the circuit board so i can put it into my project box, which i haven't found yet. After that all i need to do is make a hole in this would-be project box for the audio jack, and a square hole for the on-standby-off switch and the red LED. Thanks for this very useful instructable by the way, extremely useful for one who dreads being constricted by wires.

    I don't want to sound like a total oblivious jackass, but by 1/4" audio jack, do you mean like, the little jack to connect from the "sender" to the receiver, or by 1/4" audio jack you mean the actual thing you plug it in, because if not, then you didn't mention that part, like the fact that its a 1/4" female input that you soldered to the wires that used to be soldered to the microphone itself. Yeah I'm saying that because i just bought a 30$ wireless microphone with receiver(from the singing machine) from walmart, and i wanted to make this(although i feel bad killing this mic because it is surprisingly pretty good). So yeah, I'd really like to make this because i freaking hate tripping in my wires and my connection on my guitar is kind of screwed up so it sometimes makes a really horrible noise if i wander too far from my amp and i pull on it on accident. Anyways, i was just pointing that out because it didn't make too much sense in my brain lol. Totally making this, if i understand it right.

    [EDIT] i ment a 1/4" jack between the "sender" to the guitar, not to the receiver, because if there was a jack between the sender and the receiver, it would kind of beat the purpose of this lol[/EDIT]



    i have a wireless mic and it has a reciever, but it losses some signal on the base(low freq of the strings).

    any tips?

    yup! pinoy n pinoy!

    I think that is the problem on analog wireless systems. Unlike Digital Wireless. Im also thinking of creating digital wireless too! using bluetooth or anything ang set up mo..wireless(guitar) tz ang reciever FM radio na tinanggal ung speaker tz pinalitan ng jack to be connected to the fx. tama?

    ahm.. yup, but find a radio that have an output. I created another one using a mic with its own receiver. para d maxadong hassle.. hehe direkta na.

    it's great can you upload some demo sound?and how good is the cuality of it?is it good or is it noise?tnx

    i've just finished my wireless system too.. :) i bought a relatively cheap but ok wireless mic system and decided to mod it out for guitars.. i was impressed by the range and the quality.. i plug its out to my multi-effects which is connected to my amp.. i was surprised since there was no (or very very very little) hiss.. the sound quality when distorted was also almost the same when i try using a guitar cable.. it's only a VHF mic system that i bought, UHF is a bit too pricey for me.. one downside that i noticed is that there is slight distortion even if i am on clean mode.. very little sort of clipping.. i think it's from the transmitter and receiver stuff.. the distortion %.. so i suggest for those who would also try this, check the distortion(%) of the frequency.. i think 0.03-0.7% is very good for that..

    yeah, i ran it through my Korg AX5G.. it also has that noise cancellation feature.. :) my only gripe was that the clean sound wasn't very was not crisp and had a little clipping or drive.. i agree with oyu about the tone.. nothing beats guitar cables.. :) this was a fun project for me.. really interesting.. however, i'm back on cables since i get better tone from it.. cheers! what a nice project this is!
