"As far as cleaning and service, I've had my Helix almost from the day they came out and gig with mine 1 or 2 times every week, plus practice and prepare for gigs, so I get a lot of use. Cleaning it is pretty easy, the footswitches are self-cleaning with a few twists, and although I've never had a pedal squeak, that should just be a dash of lubricant, so I'd do it myself".
And you have never had a switch not respond? So just turning the top of the footswitches cleans them? I'll try. Thanks a lot for the post.
