Extreme Guitar Tone Experience Awaits


For the discerning guitarist, the search for the right amp is like looking for the Holy Grail. Is the 10^n yours? Listen...

Totally Original Design For your signature tone

The Powers of Ten (10^n) Amp is not a copy of a Marshall, Fender, Vox, Dumble, Trainwreck, etc.

Some guitarists feel that using a vintage amp, or a copy of one, is the answer to their guitar tone. This amp may be more than they want. If you are trying to sound like someone else, then using their gear makes sense. This amp is for guitarists who want to create their own signature tone, and don't want to be hindered by the shortcomings of an amp's tone. 

The clean tone of the 10^n sparkles. From this you can create whatever you want, with the Gainmaster, pedals, and the power of your ten fingers. If you keep buying and selling amps, in the search for tone, perhaps the 10^n can end that search for you, and you can move on to create the music that is in your head.

With built-in engineered sound technology, the 10^n performs like no other. From bedroom amp, to recording studio, to live performances in clubs or concert venues, this amp does it all. 

Once you try it, there is no going back. Some players recognize what they are hearing on the demo videos, and purchase without a test drive. They are pleasantly surprised when they receive their 10^n, since it sounds even better in person. YouTube squashes the sound, so you are getting a taste, but not the full banquet of tone that the 10^n puts out. 

If you are going to be in the Southern CA area, make an appointment to take the 10^n for a test drive, and see for yourself. Not available in stores, each amp is hand-wired by Bob Gjika, then broken-in, and rigorously tested, before going out to it's new owner. No shortcuts. This is your guitar's true voice.

Some of the components of the 10^n are custom made, some are new old stock, vintage components. Due to the lack of availability of vetted NOS components, there will probably never be more than 250 to 300 of these amazing amps produced. Perhaps, as in some other no-longer produced products, today's price will pale in comparison to what they may command when no new ones are available. 

When they are gone they are gone. Bob plans to make them till the parts run out. Same with the Germanium Fuzz Driver - when the transistors are gone, that's it.

Bob Gjika Amps


10^n = Powers of Ten

 The 10^n is  my latest guitar amplifier. It is a redesign based on the stereo 8 EL-34  single-ended amps I used to make many years ago, that became known as  the "Shawn Lane Amp" , as Shawn recorded his Powers of Ten CD and toured  with this amp. 

Thirty years later I was inspired to redesign this amp into a much more practical and usable package, with even better tone.

So here it is, and now discerning guitarists can own this ultimate Class A, high-power, single-ended guitar amplifier. 

I  still build the way I used to, sourcing custom & hard-to-find  parts, all hand-wired with no circuit boards.  This amp is powered by 4  KT-77 or EL-34 power tubes. It is very powerful and can be controlled at  any sound level with the Gainmaster.  The Gainmaster is designed,  hand-in-hand, with my amps, to achieve the driven sound of the amp, at  any desired volume.

Warning Label..
The Gjika 10n gets out of your way to create your own signature guitar tone. Big, fat, harm

What guitarists in the know, say about this amp

 "  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....
