Weil manchmal danach gefragt wird:

Um den Halfmoon-Schalter von Hammond an der Rotary-Schalterbuchse des HX3 zu betreiben, sind folgende Änderungen nötig: Kabelverbindung zu den Schaltkontakten vertauschen: Chorale an Ring des 6,3mm-Steckers, Tremolo an Spitze. Diode (z.B. 1N4148) zwischen den beiden Anschlüsse einlöten, Kathode an Tremolo.

did not know this was possible , so you end up using just one pole of the CU-1 ? also with the brake function ?

If the break function is wanted the jack and switch must be configurated like this

I always use a 2 way gitar switch. This switch has 3 positions and two switches
inside , cost about 5 Euro

okay , from the schematic , the ring remains ground in both fast and slow positions . and i assume ring must also remain
grounded for fast to function ?

Hi
Yes of course !!! It´s the same when the RUN button is on.
The switch must be for opration Slow - Stop - Fast a 3 way type with a middle
position.

The CU-1 I saw is single pole. That is why I soldered the diode between FAST and ON. It connects ON to ground in FAST position.
