    Volume "cfpt"? What's that all about?

    Post by bordonbert on Fri Jul 03, 2015 2:55 pm

    Why does the Grandmeister have a Volume control marked as C.F.P.T? I've looked at the manual and can't find an explanation and a search on the site shows nothing? I know it is supposed to be set at 12:00 and adjusted for relative loudness between presets but can anyone enlighten me as to why it isn't just marked 1 -> 10, or maybe -5 -> +5?

    (Is it German for something like "Calm, Frantic, Painful, Terrifying?)

    That's because the volume control doubles up for selecting chorus, flanger, phaser and tremolo when the fx button is depressed.

    Dooohhhh!  Thanks Tim.  Pretty obvious when someone points it out.  That's the modern approach to switches in music electronics.  It's cheaper to use a pot to generate a DC voltage and a cheap ultra low resolution AtoD convertor to act as a selector mechanism.  It feels weird after you are used to the detent clicking of a proper switch but it sure works well.  I have a Vox Valvetronix which actually builds a detent mechanism into the pot to give it fixed positions and make it feel like an original switch. It's fine until the pot gets loose and can move without too much friction.
