    Hey folks,

    i'm getting ready to wire up and Esquire build. The terminals on the CRL 3 way switch are oriented opposite of what the diagram shows.

    I assume that I should ignore that the terminals are oriented differently and make the connections as per the diagram.

    Thanks in advance,
    John

    I'd visually verify or ohm it out to check which terminals are the pole/wiper on each side first. Hopefully the text describes what's connected in each position. (I'm not familiar (yet) with Esquire wiring but could help sort it out if needed.)

    Yes, just follow the diagram to the terminals shown. Also, I would experiment a bit with the 4700pf cap value. I believe I settled on a 2200pf and the fully forward position is very usable. Adjust the value to suit your ears. Love Esquires!

    After some checking, yes wire it up in the order shown. The diagram has the two sides shifted w.r.t. each other differently than the CRL switch, but the order is correct on each side. (This is a modified Esquire wiring without the series RC in pos. 3 it seems.)

    Different, simpler wiring version of the Eldred mod using a CRL switch.

    I wired it as per the diagram as it works fine. after reading different opinions I split the difference and went with a 33pf cap and it sounds pretty good. What effect would a smaller cap have. Less bright?

    Wow, that is simple. It works the same as the other circuit?

    Before Centralab (CRL) got bought by Electroswitch in the nineties (I forget when exactly) the switch was manufactured with the lugs oriented in the way illustrated in your wiring diagram. For some boneheaded reason, Electroswitch decided to change the lug orientation, because 50+ years of these switches working just fine in the original configuration wasn't good enough for them, apparently. Just wire it like you see in the diagram, it makes no difference, electrically.

    couldn't he have just switched the switch around so it matched the diagram?

    no, because the stagger looks the same no matter what side the stator is on.

    It should be put on the record that I have been accused of failing to read sarcasm in the past :lol:

    This may help understand how it works
    3_Way_Switch.jpg

    Switch Position 1
    The red C lug (common) is connected to the red lug at the other end of the switch.
    The signal path is pickup ground (black), pickup coil, pickup yellow, red common lug, volume pot and output jack.

    Switch Position 2
    The red C lug is connected to the next red lug down
    The signal path is pickup ground (black), pickup coil, pickup yellow, red common lug, vol pot, output jack. Additionally the tone pot is now connected to the pickup by the switch.

    Switch Position 3
    The red C lug is connected to the adjacent red lug.
    The signal path is pickup ground (black), pickup coil, pickup yellow, red common lug, vol pot, output jack.The fixed tone cap is now connected to the pickup by the switch

    If you used a 33pf that is a really small value. I prefer the 2200pf to 4000pf (2.2nF to 4nF) range it will have less bass and be closer to a 'normal' pickup sound - quite usable. It will also have a small bit of the out of phase sound.

    Wouldn’t that defeat the purpose of the "cocked wah" tone and make the 1 and 3 positions sound very similar?

    I've noticed that positions 1&2 sound very similar. Position 1 may be very slightly brighter but not very noticeable. What should I expect from position one, which I think bypasses the tone control?
