Sweetwater’s discerning tone tweakers can’t help but be impressed by the Katana-500 Bass Head’s robust assortment of equalization options. First up, a 4-band active EQ covers all your bog-standard sonic shaping duties, with the option to precisely target your tone’s midrange using three low-mid and high-mid frequency options. A dedicated Bottom knob then allows you to optimize your low end for respective stages.
On the opposite end, the Katana-500 Bass Head boasts a trio of Hi Cut settings to tame your trebles. Finally, a specialized Amp Feel knob gives you access to both a Vintage and Modern tonal profile, making it a breeze to instantly swap over from warm old-school thump to a crisper, clearer, and more contemporary profile with an extended frequency range — a feature Sweetwater’s gigging bassists favor, as it makes stark stylistic swaps during your set list as easy as clicking a button.
