HIGHLIGHTS

Realize Your Perfect Bass Sound

The compact Katana-500 Bass Head brings serious bassists a next-generation sound experience backed by decades of BOSS R&D. This amp is incredibly clear, punchy, and responsive, realized with 500 watts of carefully tuned Class D power. Cab Resonance takes things even further, using high-tech calibration to internally fine-tune the power output section for your preferred speaker cabinet.

One-Touch 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 a simple button press, the Cab Resonance feature in the Katana-500 Bass Head calibrates the amp’s reactive output stage circuitry to match the unique properties of the connected cabinet. BOSS's proprietary process analyzes numerous elements, including the lowest frequency that the cabinet can produce, high-end 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 Head offers a deep selection of controls to hone your sound. Boost or cut frequencies with the four-band active EQ and choose from three low-mid and high-mid frequency options to target specific ranges. Grab the Bottom knob to optimize the low end for different stages and toggle three Hi Cut settings to smooth the sound as needed. And with the Shape button, you can instantly revoice the amp with mid-scoop, bright, and wide-range curves.

Add Character and Color

Once you’ve set up your fundamental bass voice, refine it even more with sophisticated tone-shaping tools. Amp Feel offers two selectable options to enhance the core 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 grit and aggression. And with the FX section, you can access three bass-tuned effects for color and inspiration. There’s also a Blend knob to dial in some direct bass sound for additional clarity.

Robust Connectivity

The Katana-500 Bass Head integrates a versatile range of connectivity into its compact design. Two locking-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 amp’s signal path. You can further shape the line output voice from the front panel with three mic’d speaker emulation presets and three custom settings. There’s also a dual-function output for headphones practice or analog recording, plus USB for capturing mix-ready tracks in your favorite computer music software.

Expand Your Frontiers

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