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.

Very nice kit: Beware it is NOT heavy duty plumbing pipe though!
Size: side table leg
I want to give this kit a high rating, but I need to address the "truth in advertising" bit since there may be an important disconnect between what you think you are getting and what actually comes in the box. Black plumbing used for shelving or table legs is part of an important niche in interior design. I like the industrial loft look myself and have a variety of glass, steel, and masonry elements in my home. This kit fits that look and provides plenty of "strength" for most domestic uses, like shelves or coffee tables. But they are NOT "industrial pipe" or "maximum durability pipe." Note the phrase "cast iron finish feet," which together with the other claims might lead you to think these are cast plumbing fittings. They are NOT! The feet and flanges feel like electrical conduit fittings, and the pipe sections are likely aluminum. They might be electrical or they might be multi-use, lightweight pipe. While all this might lead you to think that you're getting a truly retro, heavy-duty pipe kit made of black plumbing pipe, you are not. But, does it matter? Depends. I find the lighter pipe's smooth finish a nice "tone-down" from the rough plumbing look. All together, this kit provides plenty of strength for most furniture and the rustic pipe look, but with a nicer, lighter finish. To me that is a plus--this is a very nice kit and costs less that if you'd pieced it together from real plumbing parts (I priced it out to compare), and looks retro but cleaner. I knew what to expect because while I got this kit free on Vine, I had purchased a nearly identical kit from another seller last year. So, I'm giving it 5 stars for what it actually is and for the price, JUST BE AWARE THE NARRATIVE IS MISLEADING. Which is unfortunate because just like some people might want the heavier pipe, I'm betting more would be attracted to the look with a cleaner, lighter feel.

Great addition to our home
Model: Model B with Removable Tray
Putting together took a little time but instructions included were easy for me to follow. Putting the screws in for the shelves required a little work to get then started but nothing that I would say would be a problem to do. It is very sturdy and looks great in our room we are transforming into a hangout/bar area. I can't wait to get all my accessories in to add to it and display all my nice bottles I have. Great cart for the price.

My Cart Worked Out Perfectly For Me - Update: I got a second cart
Model: Model B with Removable Tray
Delivered sooner than promised. All pieces were present. All parts were in good condition. Assembly was done by a professional who thought the product was well done and needed very few adjustments. The cart rolls smoothly, is very sturdy, is a great size, looks attractive and is perfect for my needs. I would order one of these again. Update: I did get a second cart and I am just as happy with this second one as I have been with the first one.

Notice it is not real wood!
Model: Model B with Removable Tray
Easy to put together. The biggest complaint is it is not real wood. It looks like it is covered with contact paper!
