Confused by different results on breadboard vs pcb testing (audio/filter values)

Hi Leo-

thanks.

I have done as requested. (I have wanted to have a reason to learn LTSpice)..

I have it installed, open file, ran simulation, put probe in several places... or even in one spot..change a value ran it.. change a value ran it

I saw the top portion change, to be honest I have no clue what it means, and what I should be adjusting the values to make the above....like?.. (all lines together?)
