busking guitar mod

[GJA]

hi guys, I have a busking guitar project I'd like some help with please,
its an onboard guitar - microphone/instrument with built-in IEM- control unit,
with the following;
1 x under-saddle pickup with volume control
1 x tone control on under-saddle pickup
1 x microphone input with volume control mixed with the under-saddle pickup to the output jack
1 x earphone output with volume control from the output jack mix
1 x output jack to my amp
powered with 9V battery or passive if possible

ideally, I'm in need of a full-blown schematic is what I need please, it’s the wiring I’m struggling with I’m handy with the soldering iron, my aim is to have an acoustic guitar for busking that I can plug in a mic I have fitted to my harmonica rack, and I’d like to be able to IEM guitar and vox from the guitar before the signal goes to the amp on a single channel/ lead

I would be very grateful if you could help with the wiring

I think the OP is looking for one of us electronics geniuses to sketch it for him.

The easy route would be to strap a Yamaha MG06X to the back of your guitar. Lol. Anything is possible, but mixing and matching impedance and what not is going to be way more trouble than it's worth imho. I mean, Les Paul did make that wild Recording model LP with a looper and many amazing things, but...this is a job for a small mixer, or someone with an electronics degree.

EAE stompmix is smaller and works on 9v

Never seen it before, but that little thing is sweet. Another toy for my wishlist.

A Strymon Blue Sky is ahead (for me and toy buying) at that price point, but the EAE looks intriguing and useful.

it's been a dream of mine for some time to be able to run everything from my acoustic guitar with one 1/4 jack going out to my amp,
I use a TC helicon perform VG when I'm gigging solo, and it does everything,

I think it would be great to be able to plug in a lav mic/head mic to my guitar and plug my IEMs into my guitar and have just one output,

I have thought the easiest way is to just have 2 outputs (mic and guitar)

but I would then have to have IEM coming back from the amp via a separate unit,
my goal is a fully compact unit that does everything I need, and to be honest with all the weird and wonderful preamps such as the cherub g-tone gt6, etc, I'm surprised the brilliant techs in the far east haven't already got this concept on the go,
so what do you guy's think is it possible ?

[Cuki79]

It's always possible but you will have your guitar full of stuff... It will be heavier too

Jack white has a mic in one of his gretsch... I've read an article with pictures of the mod.


What mic are you using?

I made something similar long time ago


Note that this schematic does not work "as is". I remember when I completed the board, it was too noisy. I did the noise simulation on Spice and found out that I had to replace a bunch of resistors and ordered a super low noise op amp.

Well you can start there but you need to heavily redesign it.

The guitar buffer/preamp is inspired from a Fender acoustasonic amp.

Here is a schematic for mic preamp. I did not complete it. But I made at least the first part. The preamp stage is basically based on simplified THAT preamp (wee their white paper), I made one for my axoloti DIY pedal (look for the AGF thread).



If you don't need the guitar in your EIM then it is much simpler.

Here for example, this little box, take the phantom power from the mixing desk XLR cable to power a headset condenser mic. The mic signal goes through but is also taken into a balanced amplifier that feed a stereo mini jack for earbud monitoring.



I don't have the schematic, you can see on the back, it was drawn by hand on a sheet of paper (I know where is the sheet if you ever need it I can scan it). But in this case, you don't get the guitar sound in the earbud.

Note that if I was you, I'd use an axoloti board.

The benefit:
* It's digital, you can add all the parametric EQ to your guitar tone and even IR.
* it's digital you can add all EQ power to your vocals
* It can add reverb (processor consuming though)
* It has a built in headphone out
* It has 2 inputs with adjustable gain.
* The mod to had 5v power for a condenser mic is not too complex
* It's graphic programming (unless you are crazy like me and reprogram the block functions)

The drawback:
* It's digital: You'll need a Li-ion battery and recharge often.
* It must be programmed
