Gjika Powers of Ten (10^n) Guitar Amp Reviews by Gjika Amp Customers

Fabio Stabel: (texted to Bob)

 Hey  Bob, Fabio here... seriously, what a miracle is your amp. I can't take  its voice out of my head for a minute! I've been playing mostly on  weekends, since the rig is in my living room. The days I can't play I  usually listen to some recordings I did just to hear the beautiful sound  of it. And then every single day, 3:00 am and I'm still awaken, I have  insomnia because that tone won't leave my mind and I just wanna play  (I'm not joking, this is for real). It's insane how responsive and  expressive it is....

 Guitar Amp Reviews - here's one from Vic...




Nothing  else like the 10n (you knew that and now I do too). All of the SOUND I  ever wanted. I just played it through a Bandmaster cab packed with two  '60s vintage 12" Vox gold bells. Sensational. I've been picking since I  was 14 and this is worth the 52 year wait.

I've had many disappointments over the years. It's a new experience to hear something that sounds as good as I imagined it.

Thanks doesn't seem to be adequate.

A Fan,


Bryan Betts: (FB review)

I  love this amp. I always describe the tone I am trying to achieve feels  like holding on to a ball of solid warm glass. The 10^n delivers that  tone and feeling. I knew what I was getting in to, because years ago I  heard Shawn Lane's tone and it was unlike anything else. I love the  sound of a Marshall, but this was something different, more fluid. When I  saw that Mr. Gjika was building the 10^n, the choice was obvious. I  have had my 10^n since 19 July, 2017 and it consistently delivers that  tone 100% all of the time. It is solidly constructed, brilliantly  engineered, great looking and sounds absolutely beautiful. I definitely  want to get another one. 

Bill Walker: (FB review)

 The  Gjika 10n (Powers of Ten) is the best amp I’ve ever owned. Period. And I  don’t state that lightly. I’ve been playing guitar for nearly fifty  years and I’ve owned or played through just about every notable amp  there is…and none of them even come close. I’ve known Bob Gjika for over  thirty years and was always an admirer of his work as a guitar builder  and amp designer...What a first-time player of the 10n will note is the  amp’s lush and evocative clean tone. Coupled with a little chorus, delay  and reverb, it sounds like heaven and one could play this tone all  night and not miss the distortion.

But distortion is what we all  love, right? The 10n, as is the case with his other recent amps,  utilizes the Gjika Gainmaster as its floating front end. The Gainmaster  enables a player to get a wicked cranked amp sound at whisper volumes,  but if you want to shake the house to the foundations the 10n will do  that, too—in spades! What has always frustrated me about other amps is  there is almost always something in the tone that I try desperately to  tune out of it, twisting the knobs every which way, whether it is a  nasally midrange or a cloudiness to the overall tone. These other amps  force you to conform to what they can do. Not so the 10n. The amp is  warm and gutsy, but has a clarity and sparkle that has to be heard to be  believed. This is truly an amp that allows the player to get his or her  tone without compromise and will sound different under every player’s  hands. The way Bob puts it is: “The amp will stay out of your way.” An  apt phrase, indeed.

The amp is also built like a tank, with no  circuit boards. It’s true point-to-point with components hooked together  via terminal strips. Very few amps are built this way today, and Bob  refuses to compromise the integrity of his designs by offering anything  he feels is substandard...

In closing, I believe this will be the last amp you ever buy, and will perform flawlessly for years to come...  

George Lewis (emailed review) “BIG TONE” is here to stay!

 The Gjika  10^n amplifier is truly sublime and exceeded my already high  expectations, Bob!  I presumed warmth and girth from its big iron/big  bottle design, and yes, as you turn the volume knob it does sound  glorious, but it also had a few surprises for me.  First, it delivers  that “big tone” across the volume range.  “Dolly Dagger” by Hendrix, the  “Beggars Banquet” solo on “Sympathy for the Devil”, Kossoff’s “Fire and  Water”… these are songs I used to reserve for my wife’s trip to the  grocery store.  Now, they are on my home set list at 5:00 in the morning  as she still sleeps soundly down the hall.  Simply incredible that  these tones can be credibly had with the amp and Gainmaster on, and  the amp volume on ”0”.  Second, it is quiet for a big and driven amp,  especially for one that’s fan-cooled, and pure Class A / single-ended.   Finally, (and I guess I shouldn’t have been surprised), it is extremely  sensitive and responsive.  From bedroom to arena, audiophile quality and  all good stuff!

I was also quite happy with  our communication, and the entire purchase process.  Your videos are  complete and informative, the manual actually instructs, and you and  Michelle were always there to help if I couldn’t find the answer to my  question.  It was also refreshing to order, purchase, ship and receive  the 10^n so quickly.  No big deposit, then wait six months to six years  for build and delivery (de rigueur for high-end guitars and associated  custom equipment these days)!  Everything about my Gjika experience has  been a joy, and I couldn’t be happier!  Thanks again for everything!

Warm regards,

Hi Bob
Well  I wanted to try her sooo bad I haven't even been to sleep yet from  yesterday's traveling and last nights gig !!! I used my two main guitars  the Lentz from your room at the L.A. Amp show and the my Gibson Lee Roy  Parnell with Ron Ellis p/ups. The 10n loves the 70 cab with 55's in it  with the Lentz she seems to like the 69 cab with 75's for the Gibby but  Is close may need to play a little longer to get the match made in  heaven for the Gibby. I LOVE this amp, she exceeds anything I have ever  played and like I said I have owned / played them ALL !!! I am having  the MOST INTERACTIVE  experience between player / guitar / amp that I  have EVER had ... EVER !!! It's almost like the amp KNOWS what you want  from it AND it responds to pick attack and volume rolls better than ANY  OTHER AMP   Not by a little bit by a LOT !!! REALLY  REALLY AMAZING  Experience ... Stand by for my deposit for my second 10n I just need to  move a couple of things because I am not one of those independently  wealthy guys I mentioned in a prior text !!! Would love if I could get  it to you quick enough to have consecutive serial numbers... We"ll  see... 
I can't stop playing and I haven't slept in 27 hours !!!!

Ok,  so I have been playing with my new 10n for SEVERAL hours now and as I  said in a previous text, I have been playing, gigging, touring, buying,  and selling gear for 30+ years. I have worked in every major music store  in NY, I have played / owned several "D" Amps, Several " Train " amps (  actually knew Kenny) Tony Bruno Amps ( good friend )
Vintage  Marshall, Fender, Vox, Newer "Boutique" Amps and NONE OF THEM EVEN COME  CLOSE to the PURE TONE, PURE SIMPLICITY and PURE INSPIRATION that this  amp evokes. You have something VERY VERY SPECIAL here Mr. Gjika VERY  VERY SPECIAL indeed.


Perfect  ... I know it sounds like I am blowing smoke up your ass, but man, the  more I play this amp the more and more inferior everything else I own  sounds ( and we are talking about High Dollar, Big name amps that I  thought were as close to "THAT" sound as I was ever going to get ) I  mean this thing even without the Gainmaster is a fucking beast as well .  The cleans are articulate, focused, warm, STELLAR sounding!!! Crank her  up without the Gainmaster and I mean FUCK, it doesn't get much better  that that unless of course you are using it WITH the Gainmaster  which  just brings things up to a tonal experience that I thought was  unattainable 
Can't say THANK YOU enough
Dave P


​Yes  exactly, well it doesn't shock me ( no pun intended ) that no lift  needed on two 10N"s you TRULY are in a league of your own and that's  coming from a guy who has known and was / is friends with some real  heavy hitter amp builders!!! All joking aside, the amp is fucking like  stepping out of a 1972 Datsun B-210 and getting into a Lamborghini  Countach it's THAT far ahead of everything else
