DESCRIPTION 

With Katana Gen 3, the acclaimed BOSS stage amplifier series evolves to take your guitar ambitions to the next level. New Tube Logic enhancements enrich the core platform with even greater sound, feel, and response, including an expressive Pushed amp character that edge-of-breakup fans will love. The BOSS Tone Studio app has also been updated, making your remote amp and effects editing workflow more intuitive than ever. Loaded with inspiring tone tools and diverse connectivity options, Katana Gen 3 is your indispensable centerpiece for studio recording, live performance, and daily practice.

The Katana-50 Gen 3 model strikes the perfect balance of punch and portability, offering 50 watts of Class AB power in a compact 1x12 combo.

Katana Gen 3: Inspiration Unbound

Backed by our advanced Tube Logic amplifier architecture and reactive Class AB power, the BOSS Katana series has become a standard for guitarists everywhere since its introduction in 2016. Katana amps embody decades of BOSS development knowledge, providing professional, tube-inspired sound coupled with modern advantages like onboard effects, one-touch memory recall, deep sound customization, and reduced weight. Katana Gen 3 elevates the lineup with even more range and versatility, bringing you a playing experience that goes where no other amps can.

Refined Tube Logic Tones

Tube Logic recreates tube circuitry and all its complex interactions at a component level, putting the coveted tone and feel of classic tube amp designs under your fingers. Our approach continues to evolve with refinements to the five amp characters available in previous Katana models, including the iconic high-gain Brown type. The new Pushed character spotlights internal dynamic enhancements with the pleasing touch-responsive gain of a clean combo driven into harmonic saturation. All six amp characters include a selectable variation, giving you 12 distinctive tones to support every musical style.

“Sweet Spot” Sound at Any Volume

As every tube amp lover knows, the sound becomes richer, fuller, and more responsive as you turn up the volume. Unfortunately, it also gets way too loud for many playing situations. An external power attenuator is a common solution, but it can introduce artifacts that color the amp’s tone and feel. The integrated Power Control in Katana Gen 3 delivers the best of all worlds, letting you dial in cranked-amp inspiration with no adverse effect on the sound. Just turn the panel knob to transparently harness the level for everything from live stage playing to daily bedroom jams.

Famous BOSS Effects

Katana Gen 3 features five simultaneous effect categories loaded with essential selections from the historic BOSS library. Booster, Mod, FX, Delay, and Reverb sections offer enhanced sound quality, grab-and-go parameter controls, and three variations each for access to 15 unique effects. BOSS Tone Studio unlocks additional possibilities, allowing you to customize the onboard effects from 60 different types and tweak deep options not available from the amp’s panel. And when the optional Bluetooth® Audio MIDI Dual Adaptor is installed, you can wirelessly edit sounds on the gig using the BTS editor app on your smartphone.

Unrivaled Sound Shaping

BOSS Tone Studio for Katana Gen 3 offers new visual enhancements and graphic customization options that make crafting your tone faster and more intuitive. Explore amp and effect editing tools, change the effect order, and shape the overall sound with the three-way Contour control and multiple EQs. Dial in system-wide settings and behaviors. And organize custom setups for all your gigs. You also have access to BOSS Tone Exchange, where you can download pro setups and share sounds with the worldwide Katana community.

Save and Control Your Tones

Katana-50 Gen 3 offers several powerful tools for controlling your sounds. Four Tone Setting memories let you store complete amp/effect setups and recall them with a touch. And with footswitches and an expression pedal, you can remotely switch memories and control a variety of custom assignments that you’ve set up in BOSS Tone Studio.

Amplify External Modelers

Along with its self-contained operation, Katana-50 Gen 3 is also a great monitor for an external setup such as a direct-to-PA pedalboard. Simply connect to the Power Amp In jack to bypass the Katana preamp and use the reactive Class AB power section to amplify any modeler or external preamp.

Get Connected

Katana-50 Gen 3 includes connectivity to meet every need. Plug in headphones to practice quietly with stereo sound. And record to your favorite music software on computers and mobile devices over USB-C. All audio outputs feature IR-based cabinet sound for great direct tone, with three Air Feel types and two customizable settings in BOSS Tone Studio.

Naturally sourced, quality magnesium softgels, with bioavailability and absorption support.
Size: 90 Count (Pack of 1), Size: 90 Count (Pack of 1)
As someone who’s been using magnesium for years and likes to rotate between different forms like glycinate, bisglycinate, citrate, and L-threonate. I’m always on the lookout for magnesium supplements with smart formulas, especially those that prioritize bioavailability and absorption, since I’ve had issues with nutrient absorption in the past. This marine derived magnesium in softgel form really stood out to me, as I prefer softgels for bioavailability and absorption support. I’ve never been able to find a quality, natural, non-synthetic magnesium supplement in softgel form but I feel like I finally have.This aquamin magnesium was completely new to me and I found it genuinely refreshing, as it’s a break from the usual synthetic forms. You can tell right away this isn’t just another basic magnesium supplement. I’m impressed by this being a natural form of magnesium that contains 72 trace minerals that are naturally sourced from clean Irish seawater and sustainably harvested. I really appreciate the addition of avocado oil, as it helps support better absorption of magnesium. It's also a great source of healthy fats and antioxidants. Additionally this contains an ingredient completely new to me called AstraGin, which is naturally derived from astragalus and panax notoginseng. It was clinically shown to help support enhanced absorption. I really like seeing this in this supplement facts, it’s a big bonus for me, having nutrient absorption challenges. Although, anyone would benefit from high bioavailability and support for enhanced absorption. The focus on bioavailability and absorption was a big stand out, it’s exactly what I want to see in choosing a supplement. I usually use magnesium bisglycinate because of its high absorption, but this one actually claims even higher solubility compared to both glycinate and bisglycinate. A serving size of three oblong softgels provide 600 mg of magnesium sourced from sea water, 990 mg of avocado oil and 33 mg AstraGin. I love that my body is getting the support of a new form of magnesium that is natural and pure with the benefits of avocado oil and additional absorption support. healthy fats, I found three softgels easy to swallow, but I can see how these might be more challenging to have to take three of this size for a serving. I had no aftertaste or stomach upset, these seem very gentle overall. This is a high-quality magnesium supplement that's naturally sourced, with a focus on bioavailability and absorption support, that’s been clinically tested, and made with purity and transparency in mind. This is a true standout in my magnesium rotation. If you're looking for a magnesium supplement, I highly recommend trying it.

Most Illuminating Psych Book I've Read
Format: Hardcover
As a psychiatrist, I have yet to read a more illuminating book on how mental illnesses can develop, and how to help patients' to become free of them. Existential Psychotherapy presents a theory of the existential forces that drive all human beings--knowledge of death, of our aloneness in the world, and of "meaninglessness" (the utter inconsequence of our one life in the entirety of the universe). It shows how these forces are powerful influences in shaping human mental health and illness. Other reviewers here point out that the basic existential issues Yalom presents are well-known to academics and to many literate people who are exposed to them in that good, broad, liberal arts education we (still?) get in college. But what Yalom achieves in this book, has not to my knowledge been accomplished before (nor since): a presentation of these ideas to an audience of clinicians in a lucid, beautifully written, way that is salient to the daily practice of psychotherapy. Yalom is a rare psychiatrist who is not only a master of the art of teaching and practicing psychiatry, but for this book, ventured into philosophy, literature, history, and sociology, and then integrated the wisdom each brings to the study of human nature, into a clear and cohesive whole, a beautifully written theory of the existential dimension of men's fears, drives, and actions, and how this dimension creates mental illness or health, depending on how each person handles it. What is amazing is how such a book is now buried in the archives of (relative) obscurity, while others, recycling the same old tired ideas, reign on. So what do these lofty insights in Yalom's book contribute that is unique and powerful to us lowly practitioners toiling daily in our offices in the (seemingly more banal) task of helping patients with daily crises, complaints, resistance to change, and painful repetitions of self-destructive life choices? One very important tool: a true understanding of the power of existential concerns, not only in creating mental illness and self-destructive life paths, but, by shining a light on them-- capturing that elusive force of change: MOTIVATION. This force, and how to harness it to help patients overcome their suffering, has for me been one of my greatest challenges as a doctor. And one for which most books on psychotherapy have fallen short in helping me tackle. In the sections "death" and "will", (two of the four main sections in the book), Yalom forges a path that I could follow, to help my patients free themselves of the fears that block motivation for change. In short, Yalom shows how the anxiety about, (and thus avoidance of) awareness of our death and aloneness, can cripple us into denial, and resistance to changing those of our behaviors that shield us from these truths. But, these very fears, when faced and reframed--as the awareness of one's finite limits, and of the freedom that comes along with one's aloneness, become extremely potent engines for change. Other peoples' judgements, and fear of failure, lead us to believe that the human "judges" are the most important threat in our lives. But in Yalom's world, these feared judgements pale in comparison to the the consequences of inaction. When we live with acute awareness that we waste our only life when we are beholden to judges who are after all, mortal and alone just like us, this can shake us up to MOVE and LIVE, in this finite life, in a way other insights cannot. This example of how avoidance of existential fears leads to anxiety, low self-worth, and depression, is but one vignette in this book. Yalom applies his theory to the gamut of mental illness, and includes discussion of how narcissism, perversions, obssessions, masochism, sadism, ...the list goes on, are fueled by existential concerns. Yalom argues that they all boil down to one of two main strategies we humans employ to "forget" Death, Aloneness, and Meaninglessness: Either we escape too much into the protective cover of the GROUP, and become mindless group robots who drone through life until illness, or loss forces us to suddenly face our mortality, at which point many of us panic, or become depressed, OR, we get sucked into this defiant delusion : "I am SPECIAL"...smarter, more rebellious, unfettered by the social conventions of meek men, thus free of death's jaws". This reaction then can lead to reckless, impulsive, pseudo "powerful" behaviors that are often the fuel of many "acting out" mental problems: addiction, sociopathy, sadism, and narcissism. Enough of my words-read and feel the power of Yalom's words in this great book.

A Great Work on the Dynamics of the Human Condition
Format: Hardcover
Irvin Yalom, Professor Emeritus at Standford in psychiatry, has written a masterful book on the human condition (published in 1980). "Existential Psychotherapy" is singularly one of the best books I have ever read. Why? Yalom has combined 1) his intellectual insights in psychology with 2) his practical observations in therapy with 3) existential thought. He seeks to show that much of the anxiety we face as human beings, and seek comfort for in psychotherapy (or religion), originates from the existential facts of being a mortal, free being. He focuses on four main areas: death (our inner structure will go to nothing), freedom (we are forced to make momentous decisions without full information), isolation (we are alone in many fundamental ways) and meaninglessness (we don't have a clear picture of what it really means). From literature, psychology, philosophy and some theology (Tillich), Yalom has created a definitive text on what it means to open our eyes fully to our existential situation. It is not a depressive text, as the goal is to come to terms with our condition. And ironically, facing the truth of death, for example, makes life richer. This is much more than a self-help book, it is a philosophical-psychological masterpiece. I have a Ph.D. in the philosophy of religion and have published several articles in leading journals and don't give out the kind of praise I am giving here easily. It is one of the best books I have ever read, and I think a wide range of people would profit from it. Yet it's a difficult book, not an easy self-help read. But Yalom is such a clear writer that most readers could follow it. When he uses technical psychological or philosophical terms, he usually explains them. Otherwise, the dictionary must be used. This text would be helpful for people in the helping professions in giving an existential aspect to their work. Religious thinkers and those interested in philosophy should pick it up at any cost. Any educated person could profit from it greatly. It's a long text, and I had to break it up by carefully reading some from each of the main four parts simultaneously to get a view of the whole. It's a bit dry at times, but thoughtful, perceptive, educational in many fields, --it's ....wisdom literature....I can't think of a higher compliment.
