When you think about it, a guitar amplifier is first and foremost an instrument. It is the sound of the electric guitar. Take away the amp and you no longer have an electric guitar. It is what separates electric guitar sounds from acoustic guitar sounds.

And since it is an instrument, it is not designed like other amplifiers. With all other amplifiers, the output is exactly like the input, only louder. But with a guitar amplifier, the output is still louder than the input, but the output must sound “Better” than the input. It must have character! It must be exploitable by the player’s picking nuance to get tones that one would not find with the so called “perfect” amplifier we studied about in college. 

What do I mean by character? When you hear a guitar sound, you are hearing many things together. For example, you will hear:

1.  The initial attack—or “sting”—of the note

2.  The sustaining portion of the note that occurs after the initial “sting”

3.  Overtones and harmonics or lack there of

4.  Distortion— Both symmetrical or asymmetrical or lack there of

5.  The "Feel" of how quickly the amplifier responds to the nuance of the player’s touch

6.  The Compression of the note, also called "sag" or "blossoming"


Enter my latest design: 


The Double Trouble is a radical design and unlike any other guitar amplifier you have ever seen or heard. There is no volume, bass, or treble control. The five controls are as follows:

1.  Body – controls the loudness of the body of the note

2.  Boom – controls the timbre of the body

3.  Shine – controls the “glossiness” or trebly Shine of the note

4.  Slice – controls the timbre of the Shine

5.  Reverb – controls how much reverb is in the mix

Of course one can still control volume either with the guitar’s volume control (preferred for getting maximum clean with longer sustain) or cutting back on the “Body” and “Shine” controls.


Other features:

1.  Onboard bias meter and bias trim pot directly on the faceplate. This allows you to bias your amp anytime you wish in the time it takes for the tubes to warm up. This feature comes in handy when replacing tubes or just setting your amp (which is a musical instrument) to its best sound before a gig. The bias meter has a dial that goes from zero to a hundred. The factory bias setting is 50. If you want the amp to break up sooner, the bias can be adjusted above 50. If you want your amp to stay cleaner longer before breakup, you can set it less than 50. Once you find the perfect place that you like, you can duplicate that setting at any time in the amount of time it takes for the tubes to warm up. You tune your guitar every time you play. Doesn’t it make sense to tune your amp, especially if you are playing clubs or outdoor venues where the AC stage voltage may be too high or too low?


2.  Two KENDRICK 10" BLACKFRAME Speakers. Tens have less cone mass and therefore less cone inertia. It is a quicker and spankier response. Two tens move 39% more air than a single 12” speaker for fuller sound and better stage coverage. The blackframe speakers are made with NOS Donal Kapi 3KSP 92 lb. paper cones, the same cones found in late 50’s tweed amps (5F6A for example). Our 10’s are used by many session cats (Scott Henderson, Michael Landau, John Fogerty, etc.)

3.  Two 6V6 output tubes configured in Class AB Push-Pull. Everything you have ever heard by Hendrix, Beck, Gibbons, Ford, Bonamassa, Johnson, etc. is Class AB Push-Pull. It is the sound of smooth tube overdrive (violin- cello tones) and crystal clear clean tones. 6V6's let you hang with the drummer but keep stage volume reasonable.

4.  Massively overbuilt custom-made KENDRICK transformers. Your girlfriend was right - Bigger is better! The Double Trouble custom wound transformers are wound with thicker wire which improves the “sting” and minimizes losses. The Five-winding interleaved paper-bobbin output transformer has as much iron in it as a Twin. Such fast response, there may be times that you think the amplifier played the note before you did! I promise it will make you a better player… in the same spirit that getting off your MoPed and riding a Harley will make you pay attention to what you are doing!

5.  Multiple preamps – Just as multiple amps always sound better than one, the multiple preamps deliver complex signals to the output stage for a thicker and richer overall tone.

6.  Antique Lightweight Northern White Pine custom cabinet. Old growth wood has tighter growth rings and has noticeably better resonance.

7.  Custom-made vital components - Hand-made epoxy glass component boards with point-to-point hand-wiring. Custom-made hookup wire. Custom-made filter capacitors, custom-made coupling capacitors, porcelain ceramic tube sockets, custom-made galvanized steel chassis

8.  Analog Spring Reverb – Special circuitry with so much headroom that it is impossible to distort the reverb.

9.  Optional Padded and Lined custom American-made soft cover with a Velcro bottom-flap available for an upcharge.

10.        Entirely hand-built by professionals – Our "Dream Team" crew has been hand-building amps for a very long time. Our main wiring/soldering guy just celebrated his 28th anniversary wiring KENDRICK amplifiers 5 days a week. My cabinet guy started with us, covering and building cabinets, over 25 years ago. And I personally trained my head technician starting in 1998 – twenty years ago. No one builds better quality built amplifiers than KENDRICK. We know what we are doing.


So How does it sound?


In two words – “Absolutely Amazing”. I expect to win awards with this fine amp. When testing it, I couldn’t stop playing it. It was truly an emotional experience – not unlike driving my Porsche through the Sierra Nevadas or riding a well-trained Stallion. I could go from clean to overdrive with just my guitar volume control. I could even go from pristine to hair to overdrive by altering my pick attack. Oh Yes. You will love it. I have played about 30,000 amps in my life and I can say, “There aren’t any other amps I have played that “felt” this good!”


I am pricing these fine amps to sell at $2,995 (which is probably too low). I will be taking preorders with a deposit and the balance due when it is ready to ship. Because this is a big project, figure two to three months before the amps start actually shipping.  



Special Pre-order Offer ( an offer you can’t refuse! )


To stimulate early sales commitments and get the proverbial “ball a rollin’”, I am offering the first ten of these fine units ( make that six, because we already have four commitments) on a preorder basis for only $2,495 plus ship! Put $1,250 sincerity deposit down and pay the balance when it is ready to ship in 2 to 3 months. It is a win win. You save $500 and have plenty of time to “weed and feed”, (if you need to appease the Commander in Chief); and I get commitments on the first 10 units.


Bear in mind each amp is custom-made by me and my “Dream Team” crew, so we can customize it or cover it in whatever custom covering or grill cloth you like, usually at no additional charge.



Call me or email and let’s get you under the wire on this incredible introductory offer as you won't get it by ordering on our website.
