Experience signature Katana sound in a compact yet powerful form factor with the Katana 500 from BOSS, a 500W bass amp head with loads of control. Sporting comprehensive 4-band EQ, onboard FX, compression, drive, cabinet emulation, and selectable preamp voicing, the Katana 500 is a veritable bass control hub.

With classic BOSS effects onboard, tap tempo, and the Blend knob for dry/wet balance, you can achieve studio-quality signal processing internally. Two 4-ohm Neutrik speakON outputs are provided for either 4-ohm (500W) or 8-ohm (250W) operation with external cabinets. A direct XLR line output sports three cab emulations, selectable ground lift, selectable post, pre, or direct signals, and automatic cab resonance calibration. And when further tone sculpting is needed, you get a variable low-cut filter (up to 200 Hz), a fixed hi-cut filter, and a even a pad button to help tame the output power in quieter environments. The Katana 500 includes a power cord.

Refined Tone and Authoritative Power
The Katana 500 bass amp head brings you high-performance amplification fueled by decades of BOSS knowledge and expertise. Three unique preamp types are also available—each with a powerful Shape switch to fine-tune the character—so you'll always have the perfect sound for any style or genre.
  • Vintage: a classic tube voice with organic tone and natural drive
  • Flat: smooth, clear, and dynamic tone with rich harmonic character
  • Modern: quick dynamic response with extended bass range
Precision Soundcrafting Tools
With the intuitive panel controls on the Katana 500 bass amp head, you can quickly refine your tone in detail. The studio-inspired Blend section lets you mix in some dry signal, which you can preshape from the panel with three customizable settings for the optimum tonal fusion. A comprehensive four-band EQ is also on hand, complete with three selectable frequency centers in the low-mid and high-mid bands.

Versatile Performance Companion
The flexible Katana 500 Bass is your perfect partner for any live gig. Tone Setting memories are available for storing and recalling the sounds you create, including preamp type, EQ, Blend, and effect settings.


You can switch memories from the panel and go even further with optional footswitches, an expression pedal, and the GA-FC Foot Controller. There’s also a balanced XLR output with a switch to select between direct, pre, or post signals, plus two Neutrik 4-ohm speakON speaker jacks to augment your sound with an external cabinet if needed.

Recording and Practice Powerhouse
The Katana 500 bass amp head is equally suited for studio recording and home playing. The independent preamp gain, master volume, and drive controls let you find the perfect tone even at practice volumes. A stereo headphone/recording jack provides a direct output with effects and mic'd cab emulation with three Air Feel settings (plus a customizable setting), while USB lets you interface with computer production software and track with great tone, a perfect option for reamping.

Go Deeper with BOSS Tone Studio
To shape sounds with even finer control, reach deep into the heart of the Katana 500 Bass with the BOSS Tone Studio editor. Adjust preamp, EQ, and Blend settings, call up and tweak over 60 BOSS effects, and organize sounds in Live Sets for different gigs.


You can also shape the overall amp response with powerful global EQs and fine-tune system settings. And by connecting an optional BOSS Bluetooth Audio MIDI Dual Adapter to the rear panel, you can wirelessly adjust settings on the gig from your iOS or Android mobile device.

Toy broke in two
Color: Blue
This is a great toy for aggressive chewers. My reason for 3 stars is my dog dropped it on the tile floor the second day she had it and it broke in two. Not real happy with that. Update: The seller has been proactive and accepting of the very minor issue of the toy breaking. Responded within 24 hours and issued a refund. Because of their response I am changing my review to 4 stars.

Surviving a 8 month old heavy chewer
Color: Blue, Color: Blue
My dog is OK with it but doesn't like it as good as the whale indestructible toy I got her previously. She chews on it a little while and quits. She acts almost like it makes her nauseated. Idk though.... It gets very very sharp! Be careful grabbing it after they've chewed it.
