Siegmund Micro Tube Double Drive



The Micro Tube DoubleDrive is a high quality tube preamp, built around two miniaturized preamp tubes. These special purpose tubes were developed by the military to operate smoothly under extreme conditions with maximum life span.

The tubes unique expressive sound qualities come alive in this dual/triple gain stage design inside a footswitchable stainless enclosure. Their wide frequency range and lively dynamics distinguishes them from the more common 9 pin tubes.

The DoubleDrive has two gain stages and a switchable third (Drive). It can be set for clean boost or pushed to produce overdrive/distortion at the output. The Poweramp output has enough gain to drive a power amplifier directly. The Preamp output is attenuated to not overload the input of another preamp.

While the DoubleDrive can add much to a signal, the original quality and feel of the signal is retained. Pure transparency, musically enhanced!

Micro Tubes - Small size, but sizable warmth, presence, power and transparency.
