Does switches creating crosstalk etc?
and if the input and output socket near each other are also does?
in the image below the blue one is a switch
and you see how the input output near each other, by the way its guitar effects

 

Any two wires close together can have crosstalk between them.
The magnitude of this crosstalk depends upon how close they are and for what distance, the impedance of the input wire, and the magnitude and frequency of the output signal.
In general you want to keep inputs and outputs as far from each other as practical.

 

Do you have a schematic of the board or a wiring diagram of the device? Also, what is the chip part number?

What is the power source for the circuit, and how much crosstalk are you getting?

Since the input & output of a guitar pedal are related, I doubt you'd notice any crosstalk. Plus there are enough other sources of noise in that application that it would probably be buried. Thousands of guitar pedals are in use, and no one complains about crosstalk.

its a typical non inverting opamp and i used perf board, i got alittle little whitle noise i dont what crosstalk sound is, my box is so small,if you see in the picture the input socket "tip" output socket how close they are. are these ok? how distance it should be to avoid crosstalk or any noise
