I know my Alembic Persuader manages to sound amazing no matter where I set the only tone shaping control. I don't really know how it works or even what it is (would love to know though) but I always sound great.
Yes I get the wah wah effect
Its a frequency control, basically the same sweep as a wah pedal.. Very cool feature. In fact I had a p bass with alembic pickup and the electronics and that filter for a tone control...
