Rockbag RB23202VF

One roll for something like 4-10 pedals depending on pedal size. I used one roll for 6 pedals. Sticks ok when you handle and move your pedalboard aroud with some care. Shake it around and heavy pedals drop off. Once I left my pedalboard side up position for couple of weeks and in that time few heavy pedals had slide down few centimeters. Glue between the velcro mat and pedal stays a little "soft" so you could remove the velcor without a fight, but it also allows heavier pedals to slide a bit if board is positioned "wrong" for longer times. There are other similar products that have some serious grip, but those are more expensive and this does the job for me good enough.
