Dr.B

Blues master

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.
