Hi everyone, best regard from Santiago Chile South America

I just got this pedal and I this its what I been searching for (has many other wahs)

2 this in need to upgrade (

– how to put a led when te pedal is engaged (any circuit drawings?)

– I dont like how the switch sounds whan I move the the pedal back and forward, it somewhat anoying. I can live with this, but and upgrade would be cool!

Thanks for any info
Andrew
