XITS Amplifiers

#1 Xits Amplifiers dealer in the world

Xits x•its |e-x-its| - Fastest way out of blazing buildings (ironic given old Voxes' propensity for catching fire).
   •Large lettering found on the back of one of the infamous guitars of the incomparable Paul Weller.
   •Some of the finest sounding, feeling and looking amps ever made for guitarists by designer Mike Koski.
   •Michael Koski's way of paying homage to one of the guitarists that most influenced his life.

"I have been trying to decide what it is I should say 'about' XITS. This is a hard task and how is one to communicate in words something that helps other artists express themselves through sound? Today I will start with the basics, the why.

When I was five years of age I was introduced to the sound and images that for the most part would define who I was and am today. These sounds and images were the Beatles. Pure magic! As I like to say I was abducted by the Beatles and saved by the Small Faces and the Who. The truth being I was truly saved by Paul Weller. Yes the Small Faces and the early Who had a huge impact on me but it was Mr. Weller that helped me truly understand who I am. What does this have to do with tube amps? Well, VOX AC30's, Mod, Raw Passion, Truth... The list could go on and on. When I saw and heard my first Vox AC30 it forever changed my life. When I opened a Guitar Player in early 1992 and read about Matchless I truly knew what my calling in life was.

To be continued..."

-Michael Koski, XITS designer/builder

"....handmade by Mike Koski in North Liberty, Iowa, and I have to say I think this guy is a genius. To be honest, I’m a diehard when it comes to the classic sixties Vox sound, so just hearing about the XITS got me keyed up. But the way Koski has managed to build an amp that blends together so many seemingly divergent characteristics—refined artistry with raw assertiveness, pure old school tone with state-of-the-art specs, a “come hither” look with a “Stand back, Jack!” sound—into a whole of such singular quality has really kept me keyed up. The word I keep coming back to is astonishing."

-Chris Burgess, Premier Guitar

[Covering Update] "Pepper" has been discontinued by the manufacturer. The new "Smoke" covering will be used for all amps ordered in Pepper going forward unless the customer chooses to switch to the lighter Chalk covering. See photos below in the X10 listing for photos of a Smoke/Orange X10 provided by the first customer to receive one with the new covering. We'll have more photos posted by the end of the first week of September as our next batch of amps arrives.lkjlkjkjlkjlkjlkjlkjlkjlkj

Gorgeous construction showcasing Sprague and Sozo Capacitors, Custom Mercury Magnetics power and output transformers and threaded switch and jack chassis holes for an extremely clean external chassis appearance without any exposed washers or nuts. The amp may be affordable, but no corners have been cut in terms of component quality or cleanliness of construction. This is as good as it gets via tag board, terminal post, hand-wired construction!

Nearly everyone who has heard the X10 has reserved one. The backlog is growing rapidly with 100+ pre-sold within the first 12 weeks of receiving our first X10......which became my personal amplifier.

"Destined for greatness! Michael Koski's ear for tone is matched only by his design aesthetic.

It's the most amazing, 15 watt, Vox-like amp I have ever experienced and I'm a huge Vox fan. It has all of the detail, clarity and shimmer up top with the glorious low-end bloom of an AC30 as well as a similarly thick and complex overdrive style of that venerable amplifier, but with a bigger low end, even in 112 form, and a point of perfect saturation that comes on at a more reasonable/useable volume level. The primary volume control, or "V1", allows the player to dial in fantastic overdriven tones at low volumes without any fancy power reduction circuitry. Not sure how Mike pulled that one off, but there is an amazing array of clean to distortion tones at many volume levels via the extraordinary interactivity of the "V1" and "V2" controls.

The small size of this combo is very deceptive. When you first see the Xits X10 you are struck with its unique look and beauty, but can't possibly imagine the enormous low end and extraordinary range of tones you are about to experience coming from such a petite and portable combo (26 pounds!).

The Clean tones shimmer and sparkle when the amp is addressed with a delicate touch or set with lower V1 settings, but when you dig in, the thickness of the crunch and overdrive is literally startling. Tight and focused lows with a very broad range that extend musically in to the lower mids give this amp impressive growl to counter the perfect top end.

The "sparkle" switch is nicely tweaked to provide a subtle, but useful dose of additional shimmer for cleaner tones or to enliven a dark guitar.

The *feel* of the X10 is flawless: soft with a wonderful sense of squeezing the notes out without losing its low-end focus and string-to-sting definition.

Michael's choice of industrial grade, woven vinyl coverings in either "chalk" or "smoke" make for a unique, durable and gorgeously innovative stylistic statement and when combined with his, pseudo hammer toned, aluminum face plate with, decidedly minimalist, stamped control panel lettering, unique grille cloth options and striking logos he's created one of the best looking amp lines I've ever seen without alluding to any previous style other than perhaps something you might find in an alternate universe where a Manhattan art gallery is located somewhere in Scandinavia. In my opinion, he's broken new ground in every area of amp design much the same way that Matchless Amplifiers did in the early 90's.

If this amp sold for $1800.00 it would take me all of 5 minutes of playing it before I was racing to purchase one. It's really *that* good....and it currently sells for under a thousand dollars. I personally know a few builders who would have priced this amp at $2199.00, relying solely on the "I paid a lot so it must be great" crowd, and called it a day. It certainly *could* command that price tag to a decidedly narrower market.

Even as his introductory pricing has expired on this model Michael Koski has still kept it moderately under priced in my opinion.

This amp receives my "Highly Recommended!!" tag......in fact, I may need to come up with a revised rating system after playing this one!!"

-Stu Carter, owner Fat Sound Guitars

General Description

15 Watts of highly portable XITS Tone. Designed from the ground up to be the best amp in its class at an obtainable price point and boy is it ever!

The X10 is the younger sibling of Ms Sadie. Pure early 60's Tone that responds instantly to your touch.

This design is a single channel 15-Watt Combo with three 12AX7 driven gain stages and an EL84 power section. The X10’s tones range from chimey clean to fully saturated drive. The master-volume allows both pre and power amp gain and levels to be blended allowing unlimited tone and loudness combinations

The back opening has been sized and positioned to allow the perfect blend of sound from both the front and back of the loudspeaker. The cabinet is constructed out of ½” European Baltic Birch Plywood with a floating baffle so the cabinet resonates and comes to life as the amplifier's volume is increased.

Industrial Grade, Woven Vinyl is “welded” to the cabinet shell to provide unmatched scuff and abrasion resistance.

Customer Comments

"Hi Stu

Well the X10 is above and beyond all descriptions and expectations. I know you said it has a startling low end with the Greenback but nothing could prepare you for it. But what I love is it has for lack of better words. "Balance". It has highs but not to harsh or treble overkill... has a thump with the bottom and mids... And it sounds good with everything I have.. (I haven't tried my Danelectro Baritone yet but I will)......And it sounds equally good with all pickups of my Tele, Strat, Historic 56 & 58 Les Paul and Historic '63 ES335 Reissue and ES330.

Thanks Stu

You as always are right on the money.
My Tone Guru.......

Regards"

"Hey Stu,

Got my X-10 on Monday afternoon........I know this has been said but it bears repeating. It has great cleans, an excellent master volume and some beastly/harmonically rich overdrive when the power tubes get cooking.

It's touch sensitivity is awesome. Hit it hard and it overdrives, a lighter touch yields more clean tones. Also, the low end is there in abundance. Most of the time I played it, I was dialing the low end out a bit. That's different. Usually I can't get enough low end out of smaller amps.... :)

If you closed your eyes and listened to the X-10, having never seen one, then opened them you'd be shocked to discover that big a sound coming out of such a little box.

What a great addition to my amp arsenal.

Thanks STU!!"

"Stu,

Thanks so much for spending so much time with Gary and me today and guiding us into the entirely intoxicating world of XITS tone. I haven't been this excited about an amp since the first day I heard the Swart Atomic Space Tone. The X10 really seems like a game changer at that price point...... I loved the ambient kind of clean tone stuff you played today and I would definitely urge you to record several clips of you playing that kind of stuff and then startle the listener with the surprise of your digging in and getting that incredibly thick saturated tone...wow, that was quite an arresting sonic experience.

It was very cool when you were demoing the amp and absolutely everyone in the store turned around and slowly walked toward the amp like tonal zombies transfixed and transformed by the sheer beauty of the tones...I have never seen anything like that...a great moment that almost seemed like a commercial come to life...

The X10 seemed a perfect volume and I was really impressed at how well it did with lower volumes."

"I keep reloading the fatsound site in anticipation of more clips. This amp sounds like it will get the tones in my head. How they managed to cram OCD, schizophrenia-lite and general anxiety disorder into a 1-12 combo amp I'll never know...

This thing sounds nasty gorgeous."

"Hey Stu,

I just wanted to write and let you guys know that you hit it out of the park again!  I've been playing my new XITS X10 since I got home, and to be honest, it sounds even better here than it did in the store!  And the sound!  Everything from pristine, shimmery cleans, to "lord of thunder" distortion the likes of which make me want to pull out a solo Jeff Tweedy style!  We're talking going from complete control to utter chaos with the twist of a volume knob, or even just by digging in a bit harder.  I can't wait to take this thing to practice next week! 

Anyhow, you've never done me wrong in the 9 years I've been working with you to fill my gear needs, and it looks like you're still in top form (no surprise there)!  Thanks again to you, Mike, and Mike for all of your help and patience with me while I was waiting for the amp!

Thanks again,"

Brian S.

"Stu, Mike,

Thanks again for putting up with my emails. What a great amp!

Man 'o man.

The combinations of the X10 with a little of the RT-20, the faintest hint of dig delay and reverb, and the single coils on the Tele pretty much give me the sounds I've been fantasizing about for the last 6 months...only more so."

The perfect pairing for the X10 head or as an addition to the 112 combo.

My personal X10 is loaded with a Celestion G12-M Greenback but I also have the 112 extension cabinet loaded with a Celestion Blue. I rarely run them simultaneously, but enjoy having the speaker options; especially for recording since each speaker brings it's own flavor to the low-end and midrange of the X10's overall sonic signature.

In keeping with Michael Koski's reputation for attention to every little detail, the input jack plate is stamped with the Xits name and "8 Ohms" on one side and "16 Ohms" on the other so if you change speakers and go from one impedance to the other you can simply flip the plate around while the rear panel is removed. A nice touch.

The input jack is also artfully recessed in to the industrial grade, woven vinyl covered cabinet. Another nice, typical Xits touch.

Features

  • Baltic Birch Ply
  • Custom, hand-stitched, El Dorado leather handle
  • Reversible, recessed input jack with dual brand name and impedance stampings
  • Industrial grade woven vinyl covering in either Chalk or Pepper for great looks and durability
  • Complete range of lattice grille cloth (Orange, Silver, Turquoise, Gold)
  • Celestion Greenback as standard

Featured here in an industrial grade, woven vinyl covering that Michael Koski refers to as "Chalk" colored, with Ebony hardwood and Turquoise grille cloth.

The SADIE XS is a 15-Watt Single Channel Tube Amplifier that embodies the best of the best in regards to Tone, Components and Construction. The circuit is “True Point-to-Point”. No circuit boards or turret boards are used. The tone signal truly follows the component path “Point-to-Point”. The XITS 5-Part Aluminum Chassis is milled one at a time and is vented to allow maximum air-flow. The SADIE XS is without question the best AC15 style you will have ever heard.

"The Sadie XS is the most incredible looking, best sounding, EF86, single channel Vox AC15 style amp I've ever heard. Covered in a gorgeous woven vinyl and featured here with turquoise Lattice grille cloth and a solid, satin-finished Ebony front panel. The cabinet is solid, tuned Pine with Walnut bracing and features a floating baffle board for increased resonance and better dispersion. Internal circuitry is hand-wired via terminal strip, military grade methods with Sprague and Sozo caps.

This amp has less overall gain than the X10 and needs to be played louder to get to the good stuff, but you also have more headroom with incredibly chimey cleans that bloom and swirl in the most awe inspiring way imaginable. When cranked up to about 1:00 the amp morphs into a Classic gain machine that still cleans up perfectly with a lighter touch and with all of the harmonic complexity of its 30 watt British brethren.

Extremely touch sensitive, huge sounding, absolutely stunning visually....an amazing amplifier."

History of this Amplifier

This is the last pre-production prototype of what became the dual channel XTB. Photos of this amp are featured throughout Xits' website.

It is a single channel,Top Boost variant versus the dual chanel layout of the full production model and comes with the passive FX loop that is $175.00 option on the production XTB and has no half power switch. For me, the amp does not need the half power switch, but the Dr Z Brake-Lite, which we can install inside the combo if desired for an additional $169.00 will give you a range of volume reduction even greater than the production version's half power switch. It sounds and looks simply amazing!

The baddest, AC30 Top Boost channel amp you will ever play! Due to extreme demand, there is currently a nearly 18 month wait for any new Xits amplifier which combined with the near flawless condition of this amp and its history make it a steal. Here's your opportunity to take immediate delivery of one of the coolest, 30 watt amps Michael Koski has ever built and an amp that Michael personally feels is an important part of Xits history:

"You are getting probably the most "Historically Significant" XITS Amp. When I say "Historically Significant" it is me speaking. Not anyone else. Just as far as my amps go this one is my very first one with a 12AX7 based preamp. Before this I was only doing EF86 stuff. This amp as been played by some amazing players along with being a great friend and companion. To me this is the amp that I probably have the strongest bond with. I have explored, discovered, experimented, had moments of clarity and moments of confusion. All I ask is that you make it a good home......."

-Michael Koski, Xits Amplifiers

From Xits' Website

The PIPER XTB is a 30 Watt all tube guitar amplifier that delivers the best of the best in regards to classic mid 60's tone. The XTB provides the musician with percussive bell like tones that are highly responsive to ones on playing style. In a way this amplifier is my way of paying tribute to the sounds and images that changed my life. The XTB accurately brings to life in the modern world the direct, raw sounds of the early 60's recordings, both live and in the studio. The XTB experience not only provides great tone, it also promotes a strong relationship between the musician and the electric guitar. Are you ready to take this relationship to a higher level?
