Other than Mike Pope Flexcore, does anyone know of an onboard preamp that does 80hz, sweepable mid, and 6k-10k treble? Bartolini does 30hz Bass (really???), nice mid selectors, and a 10K Treble. Nordstrand is close except for a 4K Treble, too low for my liking. Noll is similar, but they DO that 80hz Bass. Just making conversation. But really, Bartolini at 30hz? Is the shelf just not hard, so it grabs a bit above? Because 30hz is realllllly low.
