Thanks for offering explanations of the functions Bass ParaEq! I can confirm that the high shelf control on the pedal does not move break frequency. If anyone would like further clarification or definitive answers about the functions of the pedal you can ask me here or send an email to [email protected], we're always happy to help!As you see the break frequency (knee) of the filter moves with the amount of cut or boost.
There is no graphic for the High shelf. It's not clear if the break frequency moves as much or not on the High Shelf.
