I have this Casio KA-2 that seems similar enough to the SA and SA-2. Almost all google searches send me to more SA-2's. Anyone more familiar with the KA-2, it's red, but identical on the outside otherwise. This will be my 2nd bend, the 1st being pretty basic, just pots and shorts. Now that i've learned up a bit i'm ready to make something impressive. Lovin this site! Where were you on my 1st bend?
