Not sure if this is significant, but most of the Turtle pedals I ever came across (have been very few anyhow) surfaced in Finland, just only one in Canada. No idea what kind of brand Turtle was - maybe just a trade name for certain territories. I never could track down any music gear other than guitar effect pedals by the name of Turtle.
