Quick "Timmy " Drive Question (?)

  • Hey all !


    Firstly - quick comment ... "Slim Down" ... without question the single most useful and musical Pedal Control I have ever used on any Modeler Platform ... period.


    Now .. to my query.


    Below is a Picture of the 4 x Timmy Pedals. I'm having trouble finding what is meant or intended by:-


    => calling them Tim Bass (?)

    => and what do the 1 <-> 4 presets change (?)


    Many thanks,

    Ben
