Any phantom power on the 1/2, 3/4 external switches?

[Roadrunner]

I'm building an external 4 x switch pedal to be connected to the 1/2, 3/4 inputs on the RJM22, these will be used for important but not frequently used IA's such as volume +/- and I will use the 2 others for song / bank up and down.

I would like to install LEDs as well so each click will power it on, does the 1/2, 3/4 inputs has any phantom voltage on it? As far as I tried to measure, I've seen a little less than 1vDC so I guess this is a total dry circuit but just in case…

Anyhow, if it is total dry, I will use the 9vDC output to power on the pedal.

Thanks.

Don't use a standard latching switch with LED - it won't work correctly. You need to use a momentary pushbutton, and if you wire the LED correctly, the GT will light the LED. More details can be found here:

Yap, that’s exactly the type I will use.
Eventually decided to go with a DPDT so I will have a separate change over circuit to run a Bi color LED and it will be powered from the GT's 9vDC outlet.
Thanks.
