will tapping my input jack for a tuner result in signal loss?

Hello,

I am trying to figure out how to add a tuner to my Cornish board. I want to have a "Tuner out" jack. If i simply solder a wire to the tip of my input jack and run it to my tuner out jack, will that degrade the input signal any? I will have a buffer right after the fuzz (my first effect)...

Thanks!

Any loading whatsoever will cause some signal loss. Whether you will notice it or not is not easy to tell ahead of time.

Since fidelity is not too big an issue with a tuner, it would make sense to have the input jack feed your effects and in parallel a very high input impedance buffer. The buffer would drive the tuner. Something like a FET input opamp with a bootstrapped input bias feed should do it.

In response to the questions in the forum - PCB Layout for Musical Effects is available from The Book Patch. Search "PCB Layout" and it ought to appear.
