SPECIALE DD1959 is an evolution of “Double Decker” project which is inspired by the legendary British tone of 1959. Two channels offer edge to super lead sounds (from blues to hard rock). It can be used with an amp or as a DAW where thanks to the new update a clean channel has now been added. In this mode we have three channels + solo.

SPECIALE DD1959 have two overdrive channels that integrate the gain and volume controls and a complete tone stack built in low impedance technology to better sculpt your sound. “Boost” is post effects loop in order to allow better functionality. The FX loop is equipped with an analogue mixer in order to be able to adjust from series to parallel and in the case of parallel use from dry to wet. The “Rec.out”, was designed in analog mode as it better preserves the sound details of the speaker simulator. (Sm57 in front of a V30 speaker in 2×12 “ Cab.).

Ch2 today has an “extra gain stage” that is useful for creating a sound richer in detail and dynamics. This allows you to range from a great rhythmic sound to a soloist. If we increase the gain level, enter the slight compression that helps us to play shredding.


SPECIALE DD 1959 features so many functions as 8 single pedals to obtain same flexibility. It’s equipped with Hi-End buffers and its Solo may be used also on the Bypass mode, just like a third pedal. The Bypass when used in Rec-out mode automatically activates the “clean channel preamplifier”. SPECIALE DD1959 if used in Rec-out mode becomes a three channel + boost preamplifier.

ATTENTION! The peak current of the tube in the preheating can exceed 1A (1000mA).
The HISTORY SERIES is equipped with an internal voltage doubler circuit. For this reason it’s necessary to use a stabilized power supply capable of guaranteeing a maximum working voltage of 12VDC with 500mA continuous.

Two channels + solo in “Amply” mode; Three channels + solo in “Rec. out” mode.

EXTREME AUDIO QUALITY: Great linearity of the signal designed with a a new valve preamplifier combined with a professional IC. The sound has excellent benefits.

Redesigned a new effects loop. Now there is an additional analog mixer that allows you to choose from all “series” to “parallel” and in the parallel mode you can adjust the level from “dry” to “wet”. When the fx loop is not connected, the “serial / parallel” control becomes a “Master Volume”.

SPECIALE DD1959 has increased the gain stages on Channel 2 in order to offer distortion typical of the best tube amplifiers with surprising dynamics. The choice to use a higher number of stages was chosen not to have greater gain but to get a greater wall of sound and better headroom.
