these are not obviously finnished 'designed for guitar' items. You'd defenatly need some kind of pre-amp / impedance matching before the transmitter and will also need some sort of post-amp after the reciver to make sure the signal is suitable for guitar use. You could use them but you'd need to know what you're doing with the external circuity.

Surely a guitar headphone amplifier would get it to the right levels pre-transmitter, and, as you can plug mp3 player line out (headphone) and such to amplifiers, it would be fine on the receiver end with a bit more gain?

55 mA and it claims that it has a "low power consumption".

I'm asking myself how long the battery will have enough energy to transmit audio , if we must change the battery at each concert, it's not intersting ... And what about the fidelity ?

The fidelity? Well, its primary use is for the broadcast of video and two channel audio and uses the same frequency as the commercial wireless systems. If the audio channels aren't good enough for you, surely the video channel will be. I mean, its for DVD players and whatnot, surely that is some indication.

I can't tell you how long a battery would last, it would depend on what kind of battery. I cant get the pdf file working now but I can vaguely recall the chip requiring fifty something mA. 9v batteries are apparently around 500mAH and half that for rechargeable ones... I don't know if thats the right physics fundamentals, but mathematics says that seems like an ok amount of time. Perhaps I'll be able to work it out more precisely if I could get acrobat working.

Does no one see the potential of these chips in producing a cheap wireless guitar system?

Hey hi everyone,

I searched the forum for AWM630TX but nothing came up, so maybe no one has noticed it before. The AWM630TX is a small 2.4 ghz A/V transmitter by some company called Airwave. They also make a receiver.

The transmitter and receiver are $19.95 and $29.95 respectively. That's AUS dollars, from Jaycar Electronics.

The pdf files that are linked on the bottom of those pages even show schematics for how to work it. And it runs of 5V DC.

Anyone intrigued? Thoughts on what kind of battery you'd use?

How much are the commercial wireless systems anyway?

Would there be much difference, if any, between these ex-speaker piezos and that transducer you can buy off stewmac? I mean, a piezo is a piezo, right?

Sample

The first bit is me busting out some Lenny Kravitz on the El Madonna III. For comparison, the second bit is me busting out some Lenny Kravitz on my Gibson Thunderbird Studio I bought recently. Please, be kind to me lack of groove and timing, my knuckles are swollen from the work I did to afford the Gibson. I'm using a Fender Bassman 400, and sadly, it is going through a mixer before it gets to my computer. I feel as if the mixer and the computer soundcard suck some tone out. The distorted parts are not problems with the bass but are problems with the recording.

I think its not bad for a fretless shortscale electric bass which used to be a classical guitar.

Love From Samuel.

I opened up a piezo speaker and it had a small circuit with three resistors and a transistor and three wires going to the actual piezo. There are two wires (red and green, both +ves) going to the white ceramic. In the circuit, the green wire comes after the transistor so If I'm lucky it might work if I just ignore the green wire. Any thoughts?

Whatever M, F and G mean anyway.

Love From Samuel.

P.S.

The red and green wires go to different places on the ceramic circle and are isolated from each other. The green wire's area on the ceramic is much smaller than the red's. Black and red makes more sense.

P.P.S.

Black and green, pffft, yeah whatever.

ahh u resisted the temptation of not working on a guitar on australia day

dont think i can say it for myself :D

still waiting for the grapes over the sound holes

It was more because it's a public holiday and I just assumed that Bunnings and Mitre 10 would be shut and I need more sandpaper. And they're not grapes. They're obviously bubbles coming from the sublimarine. And they're outlined in black, you just cant see it properly because of the blackness inside the guitar.

Sublimarine

We have eight records. Links off the discography and download tabs.

All our music is free to download. I think selling music is stealing from the consumer. I also believe that because I provide music for free on the internet, I should get music for free on the internet. QED.

Well it looks like you have fun modifying them. Does this bass hold it's tune? Sounds like it plays, well short of the fretboard issue(or did this issue get fixed-"I took it in to a fancy Spanish luthier and they said they'd fix it for 200-450$, I laughed at them and went to a music shop near my house where I know the guys and now it's getting flattened properly for free."). How does it sound? How much acoustic volume do you get? A sound clip would be cool if you could swing it.

Sounds like you plan to keep experimenting. On the future builds or in the future do you want to make well constructed lasting instruments? Or kinda wing it like you did on this one? It seems to me you have fun with them, and are bringing broken instruments back into action for a last run either way. So it's a good deal.

Peace,Rich

It holds its tune, except before I altered the cylinder the E string is wound around at the headstock it kind of cut into the string and it unwound itself, so now I have to use some new strings. That was mainly because of the temporary way I strung it though.

The proper sanding of the fretboard with nice equipment fell through, so when it's not Australia Day I will buy a long piece of sandpaper and put it down on something flat, and rub my fretboard against it for a bit. It should work well enough, but I'm going to have to redo the "El Madonna III" in the fretboard.

The acoustic amplification is somewhat higher than an unplugged electric bass but nowhere near an acoustic bass's volume. Through my amp, it doesn't sound bad but not wonderful. You can't really expect much from 20$ pickups. Once I do the fretboard I'll make a recording and put it up.

I can't say that the El Madonna III is well constructed, but so far it is lasting and I think it will last. I have always wanted to construct a well constructed instrument though, but I have neither expertise or tools. I made a dodgey guitar body a year or two ago, it went with the neck that came with a guitar I bought for 50$ (it was missing a bridge). But it was not well constructed nor was it lasting.

Thank you for taking the time to look into it and comment, and not say anything about the muffin with the face.

Love From Samuel.

P.S.

Should I enter it into the guitar of the month thing? Teehee.

I thought he wanted wireless for lack of any better idea. The TRS idea makes it so you don't need wireless. It does achieve the function of stepping on the floor and changing the pickup. All that aside, yes, a blower switch would be much simpler.

You know what would be cool? Staggered pickups like on precision basses with the high strings through one channel and the low strings through the other, with a stereo setup. Yeah, that would be awesome stereo.

Wow, I'm all for experimentation and all, but for God's sake, just wire up a freakin' blower switch already! You keep the main selector switch on the neck pickup, and when it comes time to switch on the distortion, you flick the big blower switch thus bypassing the selector and stomp on your overdrive. It's a lot better than trying to stomp on your distortion AND your bridge pickup at the same time.

Not if you incorporate your A/B stompbox into your pickup selecting stompbox. You could wire them up to the same switch, or have them side by side with the buttons having a large area. Two halves of circles almost touching at where they were bisected, so you could easily step on one or the other or both.

I'm very protective of my idea, and FatMike said he wants to use a foot pedal anyway.

whered you get that muffin with a face

I made it. If you like that muffin with a face you'll like the song.

Talking Muffins found on Sublimarine X

i dont like it thats the scariest muffin ive ever seen

I've got it on a shirt, it scares little kiddies.

Ah, unklmickey I have but a humble bass amp and wouldn't know such things, and I had a hard time following your explanation. I was unaware that the A/B channels had separate inputs as well, but that might depend on the amp.

Why wouldn't you want to put your signal down a USB cable?

"Hey guys, my guitar is USB 2.0 compatable!"

Or perhaps a 25 (?) pin printer cable. The sky is the limit.

Oh and in my diagram, I realised that the SPST switch would send everything to ground when on. You'd really need a DPDT.

Love From Samuel

is a USB cable code for something or am i missing something bloody obvious?!

S

Universal Serial Bus.

But that revised diagram caters for having a mono cable. If I used amp distortion with my bridge pickup and I felt the need to change pickups quickly, I think that's what I'd do. I wonder what FatMike will do...

Sorry samuel, But if i plugged the 'nice banjo' into any guitar amp of mine without the footswitch etc i still wouldnt be able to use my bridge humbucker. By its output to the ring, you're grounding it with a mono cable.

S

Oh darn you're right, I thought the tip was longer and the sleeve or whatever was the short bit, but I just looked at one and oops, my error.

It doesn't mean you cant use a USB cable.

Or an even better solution would be:

Using the 5 way switch on youre guitar must be much faster than a pedal. Look at Malmsteen on youtube (he goes from bridge to neck very quick) and practice.

Ever wonder why he can do it very quickly? Because Malmsteen's hands are very quick in general guitar playing.

So your advice to Fatmike who plays ska / punk rock in the vein of Less Than Jake / Reel Big Fish / Streetlight Manifesto et cetera is to practice guitar so he can play like Yngwie Malmsteen?

A pedal would be faster, because you can step on it whilst using your hands for other things. I don't see why you think the five way on the guitar would be faster, no matter how fast you can flick it. Unless you can flick it and play at the same time. But then, why bother? You could just stand on it.

Easier than FET switching. And if you don't have the box on the floor with the switch, or a stereo cable, you still have full functionality out of all your pickups (use the two volume controls).

Love From Samuel

P.S.

Nice banjo.

P.P.S.

The DPDT is on the floor.

P.P.P.S.

If all you've done is replace a humbucker, I could draw up that diagram better so you know which wires go where exactly.

+1 on something I wasn't thinking of..

I kept seeing a standard switch on the ground..

I wonder also, with a stereo cable/jack is it possible to use the guitar with a normal cable? Assuming that the bridge pickup wouldn't work..

Stereo jacks put L and R channels to one in mono cables.

mono:

/ \ tip +

| |

| |

| |

|__|

| | sleeve -

stereo:

/ \ left +

| |

|__|

| | right +

|__|

| | sleeve -

As in, they will become combined. But thats OK because they'd have their own volume control, so you can still pick whichever one. Just not fast on the floor.

Love From Samuel.

P.S.

I think.

the first part impressed me as thinking like a GuitarNut! ............................. but then you lost me.

think separate outputs, with the neck and middle being controlled by the 5-way, having their own volume and tone control.

the bridge HB has it's own volume control on the guitar, but the output is send through the extra connection on a STEREO shielded cable.

both signals travel separately down the same cable to a box where they are split.

from there to separate effects chains, the 2 chains joined by a A/B box, then to the amp.

one stomp on the A/B switch and you switch from normal to lead.

Oh man I would never have thought of a stereo cable. That's an awesome idea. That is certainly how I would fix the problem, if I was in FatMike's position.

Or perhaps I'd use USB cables.

For kicks.

Has anyone done anything like using Piezzo saddle based systems with the Sustainer driver?

David

I'm pretty sure those things go through some kind of weirdo circuit. I'm not sure if you can keep the string channels separate.

OK...this thread has gotten so big I can just reference to other pages

@ Radiotrib

@ Samuel McBrian- Brian

So you want to manually switch each individual driver on and off while playing depending on which string you are?

What I meant with the six amps is that you'd need those for OPTIMAL performance...just six separate coils won't make a big difference versus one big coil, because your feeding them with the same signal.

For optimal efficiency you'd want each driver to be 'tuned' for it's corresponding string. You could do this by using less or more wire, different gauge, different magnet, etc.. for even better performance you want to feed each driver with it's own 'tuned' signal, which means you need six dedicated amps...then ofcourse you need to feed those with six separate input signals. You can't just use a simple crossover circuit to split those signals from the pickup signal, as a lot of the notes (thus frequencies) on the six strings overlap. So it would be easier to use six separate sensors.

Lets say the G string has the coil turned on, and you play an open D and the open G at the same time. Surely the magnetic field will produce resonance in the G string because there is a G frequency in the signal, and surely the D frequency in the signal would just not do much at all because it'd have to be very powerful magnetic field with a frequency of D to get the G string resonating.

Does that make sense at all or am I just being optimistic?

Love From Samuel.

If you've got two pickups you could give them each their own output, both going to a box on the floor where you can put all your switching and volume and tone needs. It would be hard to control volume and tone on the floor though, and you'd look silly with two cables coming out.

Love From Samuel.

P.S.

I think controlling each pickup I have with a separate volume control is aaaaaawesome.

I don't believe you'd need six sensors and six amps. If the six coils are in parallel they could easily be turned off by an on/off switch. I realise that they may have to be staggered, perhaps a humbucker kind of thing with three coils in each single coil.

The driver I have made is from an old single coil pickup, and bending was sustained just as well as the single notes. I think this is because the poles are fairly close together and its not like its a beam of magnetic energy shooting out from the pole.

Thats it, I'm going to make a triphonic coil and if thats a success I'll consider making a hexaphonic one.

Didn't you all find that you had strings being magnetically induced into vibrating that you didn't want to when you were playing on some other strings?
