HP-3 Harmonica preamp

The HP-3 Marko Balland signature Harp Preamp was envisioned and designed in conjunction with the man, Marko Balland himself !

Marko Balland is one of France’s preeminent harmonics players and has been playing harp since 1985.

Ever wanted to get that Chicago Blues Sound for your harmonica, but didn’t have a low wattage valve amp. Unhappy with how a guitar distortion pedal works with a harmonica and microphone. Only got a clean solid state amp but want that dirty overdriven sound… then read on.

The old blues harp guys used to use small low wattage valve amps for their harps. Often they would replace the first preamp valve with a lower gain type to get smooth creamy distortion. This amplified harp sound has come to be known as the “Chicago Blues Harp” sound. But valve amps need maintenance, and can be heavy to carry around, there has to be a better way.

We still use 3 stages of JFET goodliness, operating in pure Class A, to accurately simulate an entire low wattage valve amp, including the speaker response. A JFET is a type of silicon transistor that operates in a similar way to a vacuum tube. There is no diode clipping so all the drive is from the natural compression of the jfet transistors.

There is a 1/4″ input for a microphone, and one 1/4″ output to allow connection to an amp for monitoring. Now you can get that valve amp sound from your clean solid state amplifier, hit the footswitch and the mic is connected straight to the output, with True Bypass so nothing loads down your mic and its tone.

GAIN controls the amount of gain from the first stage, there is a 2 band Baxandall EQ with frequencies specifically tailored for harmonica. LO MID and HI MID, and VOLUME adjusts the overall volume out of the pedal.

Mozztronics uses the industry standard Boss style 2.1mm center negative 9V DC socket for the power supply connection.
