Hey all, hope all is well. Just wondering if footswitches can affect tone AT ALL. Even the slightest effect I want to know

! If so, does the
Boss FS-6 effect tone any more than any other footswitch?
I understand this question may seem silly, but I just want to be absolutely sure before I get an FS-6 for my Valveking 100 head that it won't affect my tone at all/any more than the stock footswitch. Please help... You know you want to

Thanks
Regards
Jon
