External Remote switch of a potentiometer

[potierrez]

Hi!!

I recently built a parentheses miniinto a BB enclosure for using relay switches and a external expression control for the octave control.

But the jack for the expression with double connections has not fit inside. There is no room.

Is there a way to deactivate the octave with a simple remote switch?

If you connect legs 1 and 2 of the potentiometer, it will work like you put the potentiometer to zero?

thanks!!

Put a switch in series with pin 3 of the OCTAVE pot. When the switch is open, the Octave is disabled and the OCTAVE pot has no effect. When the switch is closed, the Octave is enabled and the OCTAVE pot works normally.

Thanks! But if i put a jack for a external switch, when remote switch is not connected the octave would be deactivated, isn´t it?

Not if you use a switched stereo jack like this one. Wire it so that when nothing is plugged in, the jack shorts the tip & ring connections. Alternatively, you could use a mono jack & insulate it from the Parenthesis box, but you'll have to make sure that the remote switch box isolates the sleeve from the case. Make sense?

Makes sense, but i have no room for that size of jack! I was thinking if there would be a solution with a normal jack.

What is a "normal" jack? Got a picture?

A normal mono jack. Like we use for input and output.

You can get switched stereo versions of that. Switchcraft makes them.

I found one jack with one extra lug that connect with the tip lug and when jack is plug disconnects the contact. But I have decided not to install the switch. I like the pedal and i dont want posible accidents. Thanks!
