Turning pedals off...

No

 

Should not unless the pedal has some kind of very weird construction. Some pedals do have some power on current demands however.

Which pedal is it? The Cali-tx has an issue with starting up if it does not have enough current because it needs more startup current for the transformers just for a second. So, if the power source is not powerful enough, it will sputter a bit at first.

A seriously badly grounded/built pedal might have an issue at startup as well.

 

Also, I did not want to imply anything bad about the Cali-tx, it is just a massive beast that needs power.

 

I've seen some digital pedals act funny when you plug them in or unplug them, or when messing with some other cables on the board. I guess digital circuitry doesn't always like glitches in the power or on the audio jacks. Generally I don't think it will hurt the pedal (provided the circuitry is designed with some protection) but sometimes the pedals need a reboot to work properly again.

 

Dunno if this is relevant to the thread, but my M5 refuses to boot if I use my Fulltone regulated power wart, but has no problems at all with my 1-Spot. Both have the same spec.

 

Only issue I ever have is static building up in some of my footswitches for a lovely pop when I power em up

 

The static build-up just happens, but it sure seems to plague some pedals much more than others. My Barge Concepts bypass effect looper never has this problem, while my T1M bypass effect looper always does. I have to click it 10 - 20 times at the start of a gig to get the pop dissipated. Then it's fine over the course of the gig.

 

A Lehle DC Filter can help. It does on my board, but it is not a miracle worker. It will not fix pedals that have serious issues.

Static electricity builds up in the switch and when you first hit it it discharges. I just make sure to hit each pedal once or twice during my set up so it doesn't happen during a performance
