The 1959 Double Decker Introduction:
Inspired by the legendary British tone of 1959, The Double Decker
combines the two worlds of historic amps, from blues to hard rock in one
device. From slight crunch and sexy tone to boosted hi-gain levels. We
also doubled its potential uses, from the big stage to the bedroom. The
1959 Double Decker can be used with an amp or DAW and everything is
doubled!
1959 Double-Decker features:
-Two independent channels equipped with Gain, Volume and an entire
tone stack for better sculpting of your tone.
-Post Boost with Volume control can be activated on all three stages of
the unit, (Bypass, Floor 1, Floor 2) and it is self-disengaged simply by
pressing another button.
-Tube FX Loop with series/parallel switch (especially useful when used
with amps with no effects loop or series only)
-Remote outs for connections with analog switchers.
-Balanced/unbalanced D.I. Out with Direct/Emulated option (Speaker
Sim. of a 2x12” - V30/SM57) that can be used simultaneously with
the standard output of the unit or alone as interface for excellent quality
audio recordings.
When we designed the 1959 DD, we always kept in mind the sound we
wanted to produce with rich details, harmonics and an organic sound with
tons of dynamics:!an “in-your-face” tone. We also wanted to create a
device which could easily obtain these great tones with effective and
intuitive controls.1959 DD required a lot of engineering work to fit the size,
despite using the high quality components normally used in amplifiers and
with the important consideration of space. To keep the standard pedals
power supply (9-12VDC Negative tip), we pushed our Twin Dynamic ™
over the limit, making it able to increase the input voltage many times so
as to obtain the maximum dynamic range of the signal. 1959DD is your
perfect companion on the stage, both as an "Overdrive warehouse" on
your large pedal board, or in a small setup with the effects placed in the
loop. It is also great for studio or home use providing your records an
excellent starting point for your guitar sound, Simply connecting it to your
PC with or without Speaker simulator.

1959 Double Decker Features so many functions as 8 single pedals to obtain same
flexibility. And they wouldn’t probably be enough! The Double decker is equipped with
HQ buffers and its Solo maybe used also on the Bypass mode, just like a third pedal.
As in the sample rig below, you can use your 1959DD both in front of amp and, via the
D.I.out, to mixer or DAW simultaneously for a nice live monitoring or excellent quality
live recordings.
