Micro Tube DoubleDrive




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!

Review and Sound Samples by Dimitrios Hatzisavas from Gearslutz.com

DD Review

All guitar samples are recorded with two mics (m88 where cone meets woofer and a 57 at 45 degree angle).
Fender strat with motor city afwayu bridge pickup and guitar fetish lil killer neck pickup.
The amp is a laney lionheart 5w. Mic preamps are a pair of EISEN audio neve-ish (amazing pres). There is no level matching in comparison clips. Bass clips are played by Dan Edinberg.

CLIP 1 - double drive clean
CLIP 2 - double drive bypassed
CLIP 3 - double drive overdrive - a little arrangement with two guitars and bass. Bass is a ken smith 5 string recorded direct through my custom double drive (extra features)
CLIP 4 - Distortion. Double drive (stock) used as a booster after a boss metal core pedal
CLIP 5 - Distortion. Double drive (custom) used as booster
CLIP 6 - Distortion. Double drive bypassed
CLIP 7 - Bass direct through custom double drive. Schecter stiletto 5 string. (the noise that you hear is some bad RF...working on it)
CLIP 8 - same setup as Clip 7

Hi Chris...

Well my Double Drive arrived safely & I am extremely happy. It has completely exceeded my expectations in every way.
For the first time in my life I feel in control of my sound- & what a sound!!!
It really is beyond superlatives; warm, round, clean, defined, dynamic & musical !!
- All the glowing praise from reviewers is completely justified & my little leap of faith in ordering 'sound unheard' has paid off big time.
I feel extremely fortunate to own it & very much appreciate the magnanimity with which you make these (affordably!!) available-thank you.

Regards,
Novak Conrad


Hi Chris,

Don't worry... I'm not a chatty guy... but I have to let you know that, in a live gig setting, the DD blew me away last night...
I've primarily used the same power amp/speaker combo live since 1990 (just the power section and JBL-E130-4 of a '70's Webb amp [transistor but very nice clean power])
w/ several preamps, and smaller amps w/ attenuators, etc., but the DD blows them all away, including the Avalon U5, and other high end tube pre's.
The only tube power amp that I have right now, which I can plug directly into, is a single ended EL84 (effects loop of a MacIntyre head),
and the DD iworks amazingly beautiful w/ that in my studio... very much looking forward to recording with it.
I'll be in touch when I'm ready for the Midnight Blues custom power amp.

Thanks again,
PEACE
Charlie
