Der HP-2 Leo Sayer Signature Harp Preamp ist ein speziell für Mundharmonika und Mikrofon ausgelegtes Vorverstärker-Pedal, das in Zusammenarbeit mit Leo Sayer entwickelt wurde. Er verwendet drei JFET-Stufen im reinen Class-A-Betrieb, um das Klangverhalten eines niederwattigen Röhrenverstärkers inklusive Lautsprecher-Reaktion nachzubilden. Ein CABSIM-Schalter erlaubt die Simulation lautsprecherbedingter Klangcharakteristik ein- oder auszuschalten. Der Eingang erfolgt über eine ¼″-Buchse für Mikro/Harpa, zwei Ausgänge sind verfügbar: ¼″ zur Amp-Verbindung sowie ein voll symmetrischer XLR-Ausgang für PA oder Mixer. Bedienelemente umfassen GAIN, einen 4-Band-Baxandall-EQ (Bass, Tief-Mitte, Hoch-Mitte, Höhen), VOLUME und eine LIFT-Funktion (Erdungshebung) für den XLR-Ausgang.

The HP-2 Leo Sayer Signature Harp Preamp is a specialist preamp pedal designed for harmonica and mic use, created in conjunction with Leo Sayer. It uses 3 stages of JFET circuitry operating in pure Class A to emulate the sound and feel of a low-wattage valve amp including speaker response. A CABSIM switch allows the speaker-simulation to be engaged or bypassed. The input is a ¼″ socket for mic/harp and there are two outputs: a ¼″ amp-out plus a fully balanced XLR designed for PA or mixer use. Controls include GAIN, a 4-band Baxandall EQ (Bass, Lo-Mid, Hi-Mid, Treble), VOLUME and a LIFT (ground-lift) for the XLR output.

HP-2 HARP PREAMP

Using a 12AX7 tube, and powered from an external 15VAC to 16VAC supply, this pedal runs the tube at proper amplifier High Voltages, for that real tube sound. We’ve gone old school here, we use circuits that were used to generate high voltage in old time television sets to generate the high voltage for the tube in this pedal.
There is no diode clipping in this unit, just tube compression and overdrive. We use a transistor as an output buffer and apart from that everything else in the signal path is what you would expect in a proper “tube” amplifier.

There is one main control on this pedal,   BOOST,   which goes from 0dB boost to 27dB boost. We added a CONTOUR switch, so the boost signal can be full range, or with a slight bass cut at around 160Hz. We use a similar technology to that used in class G power amps inside this beast so we can get the massive clean output we wanted.

We included an always on “full range” buffer so if the pedal is used at the end of the pedal board, we can drive long cables back to an amp without loss of tone, or if the pedal is used at the start of the pedal board, it will buffer the guitar so as to maintain high impedance loading on the guitar to avoid loss of tone.

Es gibt einige hochgeschätzte Kompressoren in Studios, oft alte Röhrengeräte mit optischem Element, die leicht einzustellen waren und immer gut klangen. Mozztronics wollte das Wesentliche dieser alten Vakuumröhrenkompressoren in einem Transistor‑Schaltkreis einfangen. Der Kompressor eignet sich sowohl für Gitarre als auch Bass und bietet umfangreiche Bedienelemente sowie einen RANGE‑Schalter und einen DYNamics‑Regler für vielseitigen Einsatz.

There are a few revered compressors used in studios. Many of these are the old valve (vacuum tube) units that used an optical element for the compression. These compressors were easy to dial in, and no matter what setting you put the controls at, they never sounded bad. Mozztronics set out to capture the essence of these old vacuum tube compressors in a solid‑state circuit. The compressor is useful for both guitar and bass and includes a full range of controls along with a RANGE switch and DYNamics control for versatility.
