Thanks guys...
That FM600 looks a real cheap way to dip my toe in the water, and that 'Shep on filters' link was really helpful. Thank you.
What I really want to do is see and hear how the resonant peak filters work. I mean the sort of filter based EQs in the John East, the ACG and Alembic ranges for instance.
The sort of thing I don't want is the auto wah type of filter. I hope I am making sense
