It’s all about tone. The SVT-3PRO’s Frequency control allows you to select the center frequency for the Midrange control, giving you a choice of five distinct “voices” for the Midrange. The center frequencies are 220Hz, 450Hz, 800Hz, 1.6kHz and 3kHz. And if that’s not enough, you can use the 9-Band Graphic EQ to custom tailor your sound even more. Or use the EQ to set up a footswitchable “second channel” for your show-stopping bass solo.
