Shape Your Sound With the 5-Band EQ

Boost or cut bass, midrange and treble frequencies with precision to sit perfectly in the mix or stand out when soloing. The EQ makes it easy to adapt your tone for different instruments, players or venues.

Add Studio-Quality Effects

While its clean tone is impressive on its own, the Ultratone K450FX takes things further with pro-grade effects. Lush reverbs, tape-like delays and shimmering choruses can be dialed in with the dedicated knobs, placing your keyboard or vocals in a lush, three-dimensional space. 100 presets provide great starting points, letting you quickly summon epic arena verb or vintage analog echo.
