So if I was a character in an adventure movie and I had to break my curse, my curse would be that glue doesn’t hold… Ever.
Anything sticky fails… Always.
After looking through the search (and I can’t believe it wasn’t there) I can find a post on how to get your Velcro to stay on your pedals.
Maybe I have garbage Velcro but I know someone has to have a trick.
I’m not above gluing, duct taping, using chewing gum… How can I get my Velcro to stay on?
I wouldn’get the Velcro off even if I tried, I only use the duct type back on the velcro, nothing else.
What I do is I make sure the surface of the pedal is clean (little bit of alcohol rub to make sure) and then I round the edges of the velcro with scissors before I attach it to the pedal. If the velcro comes off, it is always at the edges, so rounding them off will take care of that, at least a bit.
At some point, it will come off, because the duct tape stuff dries out and becomes unsticky, but that should take some years.
I haven’t read your post, as I always stop reading at the word “velcro” and post this:
This is why Japan ist the 2nd best country in the world - Takeshi’s Castle!!!
Gorilla/ Super Glue. Although you are against it, it is my chosen method. I really can’t see any other way, sorry
After I have decided I am going to keep the pedal (that is an important point!) I glue the velcro to the back of my pedals. I did consider swapping the the locking method, until I saw how expensive it was. So Velcro it is 
Ooh maybe I should cover mys lf in Velcro and stick the pedals to me.
Or maybe make a belt like the little kid from the Goonies and attach my pedals to that.
I’ll give some of these ideas a go. Maybe I’ll also look at the expensive option and fabricate my own.
I used guenuine Velcro for years and I absolutly never had one that didn’t hold on one pedal, even after a lot of travels, rehersals and gigs.
This velcro on this pedal (MI Audio GI Fuzz) is at least 20 years old, and that’s a pedal that actually was on my guitar pedalboard and I used it all the time. Never any problem and the velcro is still here :
Also I’ve used Alfatex velcro a lot and it works just as fine as the guenuine Velcro. Sorry for the non-music-related backgroud but here it is :
I think you answered your own question.
3M dual lock - like shit to a blanket.
Good point both, it is probably just the garbage they give you with the board.
This! Anything related to adhesives, 3M never fails.
I use this stuff to mount a garage door opener on the handlebar of my street bikes (triple digit speeds on the regular) and cameras on dirt bike helmets. It’s good stuff and it lasts.
Just alcohol the surface well and you’re good.
If the pedal has rubber all along the bottom you will have a hard time getting the velcro to stick to it. So if you can remove the rubber the velcro will stick a lot better.
This is the best and strongest laterally I’ve used

So just for anyone who is done with Velcro here are my ideas/research
General Screw Sizes
M2 to M3.5 (Metric): Common for smaller screws on pedals, especially with international brands.
#4 to #6 (Imperial): Used by U.S.-based manufacturers, equivalent to M2.9-M3.5.
Ranges from 6mm to 15mm (0.24" to 0.6") depending on pedal thickness and design.
Boss pedals, for example, often use screws around M3 x 8mm.
Metric: 0.4mm to 0.5mm is typical.
Imperial: Commonly 32 TPI (threads per inch).
Boss Pedals: M3 x 8mm Phillips screws.
MXR Pedals: Often use slightly smaller screws, like M2.5 or M3.
Probably too much info but I like info and sharing 
This pedal is getting a little tight anyway I think I might make a bigger one out of wood and try the washer method.
I’m thinking of just going this route after christmas. I wanted to wait and see if I’d need the duo or trio with my multi effect pedal.

I use 3M command strips, probably similar to the dual lock. It’s also possible to clean the adhesive off entirely if selling or rearranging.
That looks awesome but too $ for me. I have a nice board I’m going to repurpose from another project and I’m going to experiment with these
If that doesn’t work I’ll probably go back to the 3M and my current board but as is I don’t have enough square inches for my pedals so a size upgrade is nice and I can set the old board up for my kid so we both win.
I never had any problem with this at all and I used the cheapest velcro I could find. Do you have an example of a pedal it would not stick to?
One of the modular boards is another option but they are expensive, velcro works just as well, and my general feeling for the board itself is to stay cheap because once the pedals are on it you never ever see it again anyway; buy a cheap Donner rack board instead and spend the money you save on a better power supply.
