Suggestions about circuit diagrams?

[ellasmith]

Hello,
I want to build a microphone double adaptor so that I can put an sm58 to two different places. ie one to an effect unit and the other to a PA. So, I can have both raw and processed sounds at once.
I already have a pickup in my acoustic guitar. I want to utilise the mic for a different sound quality.
Any suggestion about circuit diagrams that could help me split a mic signal into two without losing juice?

Thanks in advance!

Welcome!

The RunOffGroove splitter/mixer would do what you want. Obviously, you only want the "splitter" part that gives you two signals from one. That's the bit in the top-left.

Another one i use often is the AMZ Splitter - it works very well. I built an A/B/Y box with this and use it to record 2 separate signal chains to the DAW sometimes, or my pedal chain and a dry copy.

What lazy Druid proposed you : 
(U1A & B dublicated for 4 splitted outputs..)




P.S.1
What Sir Mike proposed is equivalently good but I don't know if you wish to mess with those nasty          JFETS..

P.S.2
Welcome, also..

One could consider the JFET splitter to be a wonderful introduction to the world of FETs   

Before you know it, OP might be back asking how to match them for a phaser...

I picked up many 2N5457's a long time ago, so I look for places to use them.

The schematics suggested above are suitable for an unbalanced input signal, like an electric guitar. But you have a dynamic microphone with a balanced XLR output, so you really need a simple balanced microphone buffer/preamp. Like this one:
