I can vaguely remember the Schaller Tremolo Pedal as being a cult-ish item in the US; the other units here don’t ring a bell. Schaller is mostly known in the US as the manufacturer of high-quality tuning pegs for guitars, a role they have filled since the 1970s. You can still to-this-day find many otherwise flawless vintage electric guitars with amateurishly-applied Schaller tuners.
Update: a reader from the Netherlands sent in some pics of his recently-acquired Schaller KV25; an earlier vintage with top-mounted controls. Hope you fire it up and play some Shocking Blue riffs thru it Frans.
