Used Boss Katana-110 bass amplifier

The Katana-110 Bass houses a bi-amped speaker system inside a rock-solid, front-ported cabinet designed to maximize low-end resonance without getting muddy.

• The Driver: A custom-designed 10-inch woofer engineered to handle the punishing dynamics of aggressive bass playing.
• The Tweeter: A high-frequency tweeter that provides crisp definition for slap style, modern pop, or upper-register chordal work. Crucially, Boss included a physical Tweeter On/Off switch on the control panel, allowing vintage purists to instantly cut the modern sizzle for a darker, rounder old-school voice.

Preamp Voicings & Core Tone Shaping

At the heart of the control panel is a 3-way Amplifier Type switch that instantly reconfigures the preamp behavior:

• Vintage: A classic, warm tube-inspired voicing that breaks up organically when you push the gain. It’s thick, fat, and perfect for classic rock, blues, and soul.
• Modern: Fast, dynamic, and mid-scooped with an extended frequency response. Excellent for rock, metal, slap, and aggressive modern fusion.
• Flat: A completely transparent, uncolored voicing. This is ideal for electric uprights, acoustic bass guitars, or players who want to bypass the amp’s flavor and use their own external preamps, modelers, or pedalboards.
