Ceasar Diaz® SRV Tremolo Modification to all Special Edition Tube Amplifiers!

Press here to Join FireBelly Amps Forurm!

FIREBELLY is now including the famous "Cesar Diaz", amp doctor tremolo modification to all of its Special Edition amplifiers. This modification enables the tremolo to be removed from the signal path when not in use. The mod restores the loss of gain taken by the tremolo circuit, even when it isn't being used. The end result is more gain and a much hotter signal hitting the output tubes. This modification was originally done for Stevie Ray Vaughan on his Fender Vibroverb® amp. FIREBELLY is now incorporating the SRV modification to the tremolo circuit on all Special Edition tube amplifier models.

FIREBELLY is excited to introduce a brand NEW Single-ended, Class-A, 10-watt "hybrid" amp called the "SINGLE STROKE". This amp utilizes a KT66 output tube to produce a full 10-watts of power in Class-A operation and includes a two stage, tube driven reverb circuit with a spring reverb tank. The cab/combo has two different size speakers installed; a 10" and 8" Jensen to deliver 18" of total speaker cone area in an extraordinary small footprint. We've also added a 3-stage voicing control at the first preamplifier that is controlled by including a small toggle switch on the front panel. This additional feature produces three distinct voicings that can be compared to a brown tweed, blackface reverb and even a plexi-crunch setting. And, to follow time honored traditional building techniques, we have a 5Y3 rectifier to bring the voltage down and include carbon comp resistors in the input circuit.

At "FIREBELLY", the father and son team of Steven and Scott successfully "nail" the tone of vintage tube amplifiers of the early 1950's and 1960's with enhanced and upgraded re-creations of some of the finest original hand wired Blackface vintage tube amps ever produced. Our hand wired, point-to-point "style" guitar tube amplifiers are based on the most sought after vintage tube amp circuits of the early 60's. Our custom, hand wired BlackFace tube amplifiers start as low as $995.00.

We offer a variety of vintage tube amplifier models based on the original "AB763" circuit including "Standard" and "Special Edition" versions. The FireBelly line includes three vintage tube amp "Blackface" combo models loosely based upon the Fender® Princeton Reverb®, Deluxe Reverb® and Vibrolux Reverb® tube amplifiers. We offer a "PR" with a 1 X 12" at 35-watts for more headroom (original circuit was only 14 watts) , the "DL" with a 1 X 12" at 22-watts, the "VB" with a 2 X 10" at 40-watts and a special release of the 1955 "Tweed" 5F2A at 6-watts with a 1 X 10". Our "Standard" vintage tube amplifiers are based upon the same circuits, and they are offered at similar pricing levels as current, mass produced, imported "reissue" versions. We also offer a Special Edition version of the original Vintage Princeton Reverb® at is standard power level of 14-watts. With the larger cab and 12" speaker, there is no boxiness and the tone is completely open. And, check our NEW SINGLE STROKE, True Class-A, 10-watt Tweed with 3-way boost switch and tube driven Reverb based on the original "5F2A" circuit!

Enhancements to our vintage tube amps include Mallory M-150 and Orange Drop tone capacitors, authentic vintage black "tag strip" board, adjustable bias, special edition vintage AlNiCo and Ceramic speakers, six spring Accutronics reverb tanks, modified boost circuits, and much, much more. Our Blackface models can also be fitted with an optional, internal switchable, 6db Power Attenuator that allows your amp to be turned up to its full volume "sweet spot", while effective output volume can be reduced by up to 75% (-6db).

FireBelly has also partnered with Jensen and is featuring speakers that closely match the specifications of the original vintage tube amplifier speakers produced during the golden era of tone. Our PR, DL and TWEED receive vintage AlNiCo speakers while our VB is fitted with special edition, dual ceramic speakers.

FireBelly guitar tube amplifiers are solidly constructed, extremely roadworthy, readily serviceable, and produce a purity of tone that cannot be found in mass-produced, machine soldered, assembly line production guitar tube amplifiers. Our cabs are constructed of solid 3/4" finger jointed pine for overall strength and articulated tonal quality. Best of all, our amps are built in the U.S.A.!

"Reissues" are often mass-produced overseas using circuit boards with thin signal traces and modest components. Servicing circuit board amps can also be very challenging, even for the best of technicians. FireBelly guitar tube amplifiers are hand soldered vintage tube amps that are built one component at time. Each amp is meticulously constructed with only the best parts including Mallory M150, Orange Drop and Silver-Mica tone capacitors, CTS potentiometers, Sprague/Atom and F&T filter caps, Carling switches, and other top quality components that produce the best possible tone.

At FireBelly every guitar tube amplifier that leaves our shop is tested "live" and then burned in for 36-hours. All tubes are hand selected for best match to your particular amplifier. Tubes are selected for low microphonics, balanced output and specific tonal characteristics. We pride ourselves on catering to the discriminating musician, yet maintain a pricing structure that is similar to companies who mass produce vintage reissue tube amplifier models on a high production basis.

How do we produce a custom hand built vintage tube amplifier at mass production pricing? First, we build each guitar amplifier one at a time, in our own shop here in Southern California. We do not maintain an expensive sales force, carry a large inventory or produce high volume by outsourcing our work. Each vintage tube amp is individually constructed , one at a time, with the single minded goal of achieving tonal satisfaction for every one of our customers.

Each guitar tube amplifier at FireBelly is individually built from "scratch" and includes live testing and "burn-in". Only when each vintage tube amplifier passes our own testing will it be sent on its way to the musician awaiting tonal bliss.

COMMENTS FROM SOME OF OUR "DRIPPING WITH TONE" CUSTOMERS

• After having played a Firebelly PR35 for over a year now, I can safely say this is an irreplaceable amplifier. I have played through a number of high end amplifiers including several doctor Z models, virtually everything mesa makes, the entire fender high end line, vintage Hiwatt, vintage Marshall, orange, vintage Vox and Soldano just to name a few.

This amp embodies everything I have wanted in tone. Rich on every spectrum and so pleasing to the ear that I can literally not get enough. Every note seems to drip like honey. Thank you Steve.

Patrick G., Meridian, ID

• ...left a message at your office in an attempt to convey to you personally by phone how incredibly pleased I am with this amp....Aside from cosmetic flawlessness every aspect of its construction appears solid as a rock! The tone is beyond expectations and at idle it is as quiet as a mouse (very important for the kind of gigs I play). The verb is lush, but not overwhelming and responds to the level pot intuitively. The tonal adjustability is also amazing. How you can continue to make an amp of this quality at your price point is beyond me. Thanks again for everything, Steve!

Rick R., San Diego, California

• It sings! I am entirely IN LOVE with this amp! All the features work as expected . The tone is warm and wonderful. The tube break up is great. I’m on the edge of a mountain of vibe... I am in total and complete bliss. You build an INCREDIBLE amplifier! Thank you so much, again. This is the finest piece of equipment by far that I have ever owned...including guitars. I am ever grateful. The Panderers love, praise and endorse your fine Firebelly Amplifiers. A complete homerun my good man!

Scott Wynn, The Panderers, Moores Hill, IN

• I found this amp through an extensive search looking for an amp with a specific sound. The sound of this amp takes me there. The sound quality, words cannot describe. Have you ever gone to a recording studio and listened to a player and said "why can't I get that sound quality, it must be magic" Mystery solved, your ears will be stunned. Mine were. With this amp I hit the perfect low and in that moment just before I hit the high I say to myself its not going to get there but, it does and I'm just in awe. It will do this up and down the volume dial + master volume dial to make those tubes hum warm fuzzies.
The low end is just incredible".

Steven J., Sunrise Beach, MO

• It was a pleasure doing business with Steven. He took all my calls and helped me decide on speakers and other options. He is very passionate about his amps and it shows in the finished product...I'm glad to have found FireBelly amps when I did.
