BOSS Katana-500 bass head

Realize your perfect bass sound. The compact Katana-500 Bass Amp gives serious bassists a next-generation audio experience backed by decades of BOSS research and development. This amp is incredibly clear, powerful, and responsive, realized with 500 watts of carefully tuned Class D power. Cabinet Resonance takes things even further by using high-tech calibration to internally fine-tune the power output section to your preferred speaker cabinet.

One-Click Cabinet Calibration. Every speaker cabinet has its own characteristic impedance curve and frequency response, and these elements affect how the amplifier feeding it behaves. With the push of a button, the Cabinet Resonance feature in the Katana-500 Bass Amplifier calibrates the amplifier’s reactive output stage to match the unique characteristics of the connected cabinet. Our proprietary process analyzes numerous elements, including the lowest frequency the cabinet can produce, high-frequency resonances, and many other factors. With this information, advanced processing dynamically enhances the output to provide superior feel and response, powerful lows, and high-definition overall sound.

Craft your core tone. The Katana-500 Bass Amp offers a deep array of controls to fine-tune your sound. Boost or shape sharpness with the four-band active EQ and choose from three low-mid and high-mid frequency options to target specific areas. Turn the Bottom knob to optimize the bottom for different scenes and toggle three Hi Cut settings to smooth the sound as needed. And with the Shape knob, you can instantly change the amp's voice with mid-scoop, bright and wide-range curves.

Add character and color. Once you've set up your basic bass voice, refine it even further with sophisticated tone-shaping tools. Amp Feel offers two selectable options to enhance the basic sound for different styles. Modern provides an extended frequency range and more dynamic sensitivity, while Vintage introduces the warmth and character of classic amps from the past. Comp and Drive types are available to control dynamics and introduce grain and aggression. And with the FX section, you can access three bass-specific effects for color and inspiration. There's also a Blend control to dial in some direct bass sound for added clarity.

Robust connectivity. The Katana-500 Bass Amplifier integrates a versatile array of connectivity options into its compact design. Two latching-style speaker outputs support high-current operation, and the XLR line output can send a simultaneous signal to a house PA from direct, pre, or post locations in the amplifier's signal path. You can further shape the line output sound from the front panel with three microphone-emulated speaker emulation modes and three custom settings. There's also a dual-function output for headphone practice or analog recording, plus USB for recording mix-ready tracks into your favorite computer music software.

Expand your boundaries. Using BOSS Tone Studio, you can view and edit all amp parameters on your computer and access over 60 BOSS effects to swap out alternative types for the Comp, Drive, and FX sections. Connecting a GA-FC or GA-FC EX foot controller provides remote control of numerous amp functions, including the front panel user memory and two additional memories. And with the optional Bluetooth® Audio MIDI Dual Adapter, you can stream music from a mobile device and wirelessly shape tones using the BTS editor app for iOS and Android.
