[AudioI] AudioInjector and Guitar

[Matt Flax]

Do you know any circuits online of guitar preamps which are known good ?

 

One idea is to design one up - possibly using the Pro soundcard first - because of its available power rails and low noise design and the AIABS inteface which would make it reusable.
 

 

We could work through the design of a preamp there seems to be some interest.

I was really excited to see this because I thought maybe somebody had figured it out. Imagine my disappointment to see that it was pointing back to me. I have not actually figured this out. I am dealing with six extremely low power output single coil pickups and the noise is six times worse than one would get from a regular setup so it’s sort of worst case scenario here.
 
 

 
 
I am also building the actual guitar so I have been occupied with a multitude of other problems.
 

 
 
Some ideas that I am considering but have not yet tried are to run the guitar signal through some sort of effects box, a booster for instance, that will do impedance matching and deliver a more useful signal to the audioinjector.
 

 
 
In my case I’m thinking of trying six cheapish noise gates since hardly ever am I playing all six strings at once.
 

 
 
Another idea involves using a high impedance Phono preamp as a buffer.
 

 
 
My advice would be to build your device, then if necessary visit your friendly guitar store and try out different stomp boxes as buffers. That’s what I plan to do soon now that they are open to in person business.

Hi Harold,

 


 

 

Some people in the past have build guitar rigs, there is most likely good information here :

You can also contact those people directly if you don't get a response here.

 Hello Audioinjector Users,
 
 
 I bought the audioinjector soundcard (stereo in/out via rca connectors) in order to build a guitar looper pedal. Will I need to adjust the guitar signal in term of gain? Or Can I directly plug the guitar  into the soundcard (just physically transforming jack into rca).
 
 
 If anyone has experience with it, thanks for sharing your feedbacks! 
 
 
 Regards,
 
 
 Harold
