this is a passive A/B loop switcher. The switching is fine but the problem is it's too noisy.
Can someone please correct the grounding or even the wiring? please. this is my very first project. :icon_cry:
Did you test for beep between the input cable sleeve and every jacks sleeve lug ?
^ sorry, what's a BEEP?
i apologize for my dumbness. :D
a DMM, Digital Multi Meter test {for actual continuity'
Set DMM range-wheel to diode-mode, at the: --->l--- symbol, when the lead-probes are touched together a beep sound indicates the connection, and this beep should occur when the probes are touched at the far ends of any trace/lead/wire [or combination thereof] indicating a 'connection' that looks like a connection, is 'measures' as connected. [or some very low resistance].
if you're using a metal box and metal switchcraft/neutrik jacks the jacks will all ground themselves together by touching the metal of the box. If you're using another type of box (plastic, wood) or using plastic jacks you'll need to connect all the grounds. Do a continuity test like Pete suggested to make sure.
You might want to consider switching the outputs too, not just the inputs. Any pedals that you have in the inactive loop that produce noise (Dist, OD, Compressor, phaser, etc) are going to dump that noise right out into your output, even when that loop isn't in use.

maybe i'll try this, because the enlosure is not yet drilled.

this worked. thanks.
BTW, how do you solder the lugs of the 3pdt switch properly? the plastic part almost melted but the solder still doesn't stick.
Make sure you're using the right iron and the right solder. Maybe you have lead-free solder, that requires more heat to melt.
