input impedance of the pedal is loading the bypass signal

good day

is this really bad? if your using the non true bypass wiring like this:
what makes really bad or how it worse if you mix the impedance and the bypass signal with your guitar? anything positive on this? just a little positive if your using this wiring style.

I think this thing should name "vintage stompswitch wiring" not non-true bypass because it has a bypass functionality also.

are two of the logs on the switch always connected together, or what does the colored line do?

If not, this is the same as many vintage pedals. It will load the pickups some

good day

what do you mean load the pick up?..it loads more high frequency or low frequency?..but i tested this kind of stompwire many times the bypass mode is the same as the normal guitar..in other words its okey to do this kind of wiring..

i wonder how the MXR distortion plus became famous inspite of this kind wiring it use?..

I think there's nothing wrong to follow this kind of stompswitch wiring..and beside its noiseless and no pops audible when you turn on the fx..its actually im using this kind of wiring to my diy pedals with led indicator. and i have no problems with pops and noise..

thanks..any opinion if im wrong..

You could try a value of anything between 1M and 4M7 for the resistor, and you shouldn't get any loading effects, when the input of an effect is loading down your guitar signal, it will cause a loss of highs, making the sound muffled, and it will cause distortion, so you want the input to have a very high impedance to present a light load to a signal from your guitar....

If you are happy with it then go for it. It works!

The problem however is when using lots of pedals. The high end will suffer. You'll loose some volume too I would guess...

But as drnomis suggets a high input impedance will help. Not all pedals are easy to convert though.

If you use dpdt stompswitches you have the option of a millenium bypass solution. But if true bypass is not what you're after, then why bother.

Just buffer the input. Suddenly it goes from a crappy compromise to a perfectly decent system.

Would you buffer the input of the effect-pcb or the input jack? I'm thinking if the buffer in your line of thought is placed before or after the switch?

hello..

for those who suffer from "pops" and "noise when you turn on your fx and using dpdt stompswitch only ..use this kind of stompswitch wiring its true bypass also..

don't worry about the millenium led indicator forget it...makes the things simpler use this kind of switching..its direct and simple..

many pedals is using this kind of wiring scheme..its alright don't be afraid..go on try it..

i think theres no volume lost..maybe put a booster if its go low..

thanks..

you put the buffer directly after the input jack, yeah.
