Atomic Power Supply

Der Tube Drive™ ist ein Overdrive-Pedal mit drei Doppeltrioden­röhren, die mit echter Verstärker-Plattenspannung (300 V DC) betrieben werden. Die sechs-stufige Röhren­schaltung ist präzise voreingestellt, um hochsymmetrische Clipping-Verzerrung zu erzeugen. Der Sound ist enorm, harmonisch gesättigt und super-geschmeidig – von mildem Blues-Breakup bis hin zu cremiger High-Gain-Sättigung ist alles möglich. Es besitzt einen vollständig röhrenbasierten Signalweg, eine aktive „Baxandall“ Klangregelung (ohne Einfügungsverlust) sowie eine aktive Bass-Boost-Kontur für mehr Tiefton. Das Pedal erlaubt durch Röhrentausch eine Charakter­änderung hinsichtlich Gain und Klang.

The Tube Drive™ overdrive pedal contains three twin-triode vacuum tubes operating at real amp plate voltage (300 V DC!). The cascaded six-stage tube circuitry is precision-biased to generate highly symmetrical clipping distortion. The sound is immense, harmonically-saturated and super-smooth, able to go from mild bluesy breakup to full-on blistering distortion. It features an all-tube signal path, an active “Baxandall” tone stack (with zero insertion loss), and an active Bass Boost contour for added low end. The pedal allows you to fine-tune the character by swapping tubes to change gain and tonal response.

tube drive

The real McCoy! The SR-71 Blackbird™ ‘Tube Tone Engine’ is a genuine all-tube preamp in a compact pedal. Designed for great versatility, the  SR-71 adds additional clean/drive/distortion channels to vintage/boutique guitar amps or works as a professional stand-alone direct recording tube preamplifier. The clean channel possesses a beautifully pure, ‘glassy’ character and audio circuitry within the drive channel is tuned to generate a rich, full-bodied and devastatingly smooth overdrive.
