BOSS Katana-50 MkII EX 50W Guitar Combo Amplifier Black
The latest addition to their highly praised Katana amp series, BOSS delivers an even more powerful punch with the Roland Katana-50 MkII EX 50W guitar combo amplifier. This portable amp is stage-ready for easy use but is versatile enough for studio and home recording, for the best of both worlds. Featuring five effects and five unique amp characters, the possibilities of creating your signature sound are plentiful with the 50 MkII EX.
Big Power in a Compact Size
With BOSS' tube logic design, you can still have the punchy, rich sound you’re looking for without angering the neighborhood. It delivers that big amp impact and feels just as warm and responsive as a classic tube amp, giving you the perfect sweet spot. Even at very low volumes, the power control gives a great response, combined with the power amp in jack you can cut straight to the tube logic power section. Complete this with an optimized input that has an adjustable gain and high-pass filter, thanks to the BOSS Tone Studio, and you have an outstanding powered cabinet.
Customized Acoustics for Limitless Creativity
Shaping your sound has never been easier with the included five-amp characters (clean, crunch, lead, brown and acoustic), each one also having up to five variations, and you can find a tone that works for any playing style. Instead of having to lug around a heavy pedalboard, this portable amp also conveniently features five effects sections (booster, mod, FX, delay and reverb) with each having up to three variations for ultimate tone versatility.
The BOSS Tone Studio tone editor lets you further customize your sonic character with over 60 different effects, adjustable routing and four independent chains to change the order. You can then instantly recall your saved, preferred effects and amp character choices with a tone setting. You can save four tone settings that you can then choose via the panel or optional footswitch (GA-FC and GA-FC EX, sold separately) for on-the-fly convenience.
Seamless Connectivity for Instant Setup
It's easy to link two amps with the stereo expand feature which allows you to control everything from the 50 MkII EX and creates integrated surround sound. With USB, line and phones/recording outputs, it’s a seamless transition to connect with any PA or DAW system. Last but not least, the miked cabinet emulation and air feel settings from Tone Studio give you total control over all of your connected sound.

Great little amp for almost anything

I am a semi-pro guitarist who currently plays at church. I've had a tube Classic 20 head, and jumped into modeling early with a Peavey Transformer 212 and more recently the Yamaha THR. I have a Fender ToneMaster Deluxe Reverb which I absolutely love the clean and breakup tone of (great pedal platform), but don't always want to tote a pedalboard (MS-3 with TC drives and others). I bought the 50 mkII EX to try out for a small, portable church amp. I figured I'd return it but when I first plugged in I was impressed. This Katana fills the bill for its built-in effects, ease of use, configurability, sound quality and volume. Just a little setup with Tone Studio and I had the global EQ set to low-pass, high-pass and tune out anything I didn't like. The effects are almost as good as the MS-3 (reverbs could be better) and I can set the effects order also. It also has a dedicated line out (speakers on) and can use the GA-FC EX controller which I highly recommend for live. Of note, 50 watts in this thing is loud enough for a drummer. The tones are good enough for working musicians and even recording. Even more so, it feels right. The response is quick and direct, most likely due to the fact that it is an analog pre/power amp. The digital EQ and effects seem to be where the modelling come from. If you are on the fence about a purchase, you won't regret it; however, do take the time to tweak and customize with Tone Studio. I had tried the original Katana and didn't like it, but the MkII and especially the EX changed that. The EX gets all of the upgrades except the effects loop of the 100W version. Awesome purchase!
I would buy the Katana Amp again without any hesitation!

It's a game changer. In over 5 decades, I have played with dozens of the greatest jazz musicians in the world. Because of the demands of the business, both in performance and travel, I have sought out amplifiers with a small footprint, power to spare, and built ruggedly for travel over the years. This amp fits the bill and more. I no longer use a pedal board; the effects on board are killer, and the ability to save settings is a critically important and practical feature; regarding any performance. The net? I'd buy it again!
