Dr.B
Bright switch
Deep switch
Ultralinear master volume
3-modes selector
2w/20w switch
Cover all the early US sounds with a single amplifier. The Fxamps Dr.B was one of the first amp to include the 3-way selector, allowing you to chose from a range of various era typical sound.
50′ position will give you the early american blues tone. Fat and tweedy, it targets warm blues sounds, but can also be used as a pedal platform, to use a variety of drive/fuzz pedals in front of the amp. Use the bright switch to give it a little bit of edge when used with single coil pickups.
60′ position will give your a hotter and brighter american tone. Powerful and hot, loads of bass, incredible definition with detailed highs, typically blackface. Perfect for blues licks with reverb, arpeggios with a touch of delay. Switch OFF the bright switch to give it a more neutral sound, if you plan to use pedals in front of the amp.
Boost position sounds similar to the 60′, but with an additional gain stage. It will give you that fat and slightly fuzzy sound you loved so much on many albums. Hot and bassy, it can become wilder with higher gain settings. Perfect for solos, SRV kind of blues, or more modern pop-rock music.
Features
Quiet play
The Dr.B has the special « ultralinear master volume » technology, designed to play at any level, even at very low level at night. That master volume is very progressive, and easy to set even at low level. There is no jump in level like with a typical master volume, and it remains progressive until the end of the course. The amp also has a 20w/2w for the most quiet conditions, with a slight frequency correction in 2w mode to compensate for the bright response of some speakers at low level.
No Bias System
Change your tubes yourself, at home, no equipment needed. Freely choose between 6L6 and EL34 power tubes, you can even mix a 6L6 and an EL34. Procedure is quick, easy, and without risk. This will save you hundreds in maintenance every year, and will allow you to test many tube brands and combinations.
Big tubes
Were other amps uses cheaper EL84 tubes to get 20w, all FX amplifiers uses big EL34 or 6L6 tubes, just like the big 100w stack amps. These big tubes give a more massive sound, with increased bass response, even a low level. BIG TUBES = BIG SOUND!
Smart connections
The head version (and reverse head) features two speaker outputs in parallel, along with a 4/8/16 ohms impedance selector. This allows a variety of possible connections, with one or two cabinets from various impedances.
The combo version offers exactly the same outputs, and the speaker is externally connected (cable included). This allows for multiple smart connections. You can use the internal speaker alone, internal speaker + external cabinet, one external cabinet only, two external cabinets. It also allows the use of an attenuator with internal speaker or external cabinet, and the use of a loadbox for silent recording. Finally you can also use the combo as a cabinet for an external amplifier (In that case, turn off the amplifier section of the combo!!!)
DC tube heating
Heating tubes with DC current is quiter than the usual AC wiring. It takes more time to wire, and it’s a little bit more expensive, but it’s really worth it. Your Fx amplifier is guaranteed to be as quiet as possible.

Plugging into the Drb by FX Amplification was a revelation…I played many many amps and thought my tone was pretty good, then the DrB came along. Each string rings clear as a bell, it got depth, clarity and tone to burn…EVERY show I play I’m asked about my tone and I point straight to the FX DrB

Le clean que je cherchais, son équilibré avec des basses bien présentes. Réaction immédiate au touché de la guitare. Que ce soit ma LP ma Strat ou ma godin en P90, j’ai l’impression d’avoir changé de guitares.
Ma femme qui n’est pas une oreille a entendu la différence.
Et la position 2w c’est génial pour les voisins.
Pour la housse ça a l’air hyper costaud.

Mon Doctor B.
Je pourrais vous parler de son superbe clean sur les positions Brownface ou Blackface, de son crunch bouleversant façon Bassmann (mon préféré), que les pédales le sublime, de ses réglages ultra progressifs et efficaces, de son système d’atténuation qui le rend utilisable à faible, voire très faible volume certes mais avec énormément de plaisir et ça fait une très grosse différence.
Mais je préfère vous dire que quand on achète un ampli boutique, on achète aussi un artisan. FX est toujours disponible, à l’écoute des demandes et des interrogations, c’est un passionné plein de rigueur, très ouvert et accessible pour s’adapter aux demandes. Et cela se ressent dès que l’on bascule ce beau switch qui fait s’allumer cette lampe violette. Le montage ultra propre en point-to-point n’y est pas pour rien dans le rendu sonore. (Certains CS célèbre devrait s’en inspirer…).
Bref j’adore mon DrB, et depuis le reste de la gamme me fait de l’œil. Un petit ACE Colt ?

Je viens de toucher mon Dr.B… Enfin ! Mais ça valait le coup. La promesse d’un clean impeccable et chaleureux quelque soit la guitare est tenue. La position 60′ est ma préférée. Je joue cet ampli sans pédale, pur son avec trois guitares différentes : télé FGN, D’Angelico Atlantic type LP, Hagstrom demi-caisse jazz. Toujours un son extrêmement défini, dynamique à l’attaque, précis, sans sécheresse, plus qu’un ampli c’est un instrument de musique. Silence total, potards extrêmement progressifs permettant de jouer à tout les volumes sans perte de définition, y compris très bas. Ajoutez à ça une finition impeccable. Bref la promesse est réalité. Le seul problème c’est l’envie d’en tester d’autres, attention à l’addiction.
