3P2T

[Dave da Dude]

Is that what's to make a "True" Bypass?

 

I've got a cheap A/B/Y that has six lugs on the body of the switch. Does that make it a 3P?

The 6 lugs make it more than likely a DPDT (Double Pole, Double Throw) switch. Check it with a multi-meter's continuity function to be sure. A 3PDT is triple pole, meaning that it switches three circuits at once. A true bypass can be done with the DPDT. The two center lugs would be wired to the input and output jacks, the two bottom lugs are wired together, and the top two lugs are wired to your circuit. If you wanted an effects loop that you could switch out of your signal path at will, you'd wire the two top lugs to their own input and output jacks.

 

If the box is upside down, the input lugs is the center left hand lug, with the output to the loop at the top left. Input to the switch from the loop is the top right lug, and the output to your amp would be the center right hand lug.

Hey, thanks bluestrat.

 

I'm about to quit working (Leak Test Fixture Plate for Honda, ) and go out to the other building here at work and let the tube amp loose for the first time

 

Talk to you later, if I can hear
