Turbo charge your amplifier with the HP-2 Leo Sayer Signature Harmonica pre amp.
Leo Sayer, the great singer, songwriter, who is also a great harp player says,
‘I have been trying many pedals over the years but couldn’t find one that suited me. Andrew McDonald, Mozztronics, took on the challenge and we tried many prototypes before getting to the final stage. ‘Break up’ is fully controllable from clean to distorted, and the EQ is biased to a sweep-able low mid range which suits the range of the harp superbly. It’s a great pedal which gives an instantly pure sound!’
Ever wanted to get that Chicago Blues Sound for your harmonica, but didn’t have a low wattage valve amp. Were you unhappy with how a guitar distortion pedal works with a harmonica and microphone. Only got a clean amp but want that dirty over driven sound. Don’t want to lug an amp to gigs but want “that” harp 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 pre-amp 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.
My original HP-1 harp pre-amp has proved to be very popular. It has a single tone control, a gain and a volume control. Leo Sayer has been using one for quite a while now, and he doesn’t take his amp to gigs any more, he just plugs his harp through his HP-1 Mozztronics Harp pre, and takes the balanced XLR out to the PA.
A Signature pedal had to retain the sound from the original pedal but offer many more features, so i conjunction with Leo, we sat down & worked out all the things he wanted (and a few more) in this new HP-2 harp preamp.
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 which is now switchable with the CABsim switch. 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 two outputs. The first is a 1/4″ to allow connection to an amp for monitoring. The second is a fully electronically balanced XLR to allow for direct connection to a stage box or mixer. You can use both outputs at the same time.
GAIN controls the amount of gain from the first stage, there is a 4 band Baxandall EQ with frequencies specifically tailored for harmonica. BASS, LO MID, HI MID and TREBLE, and VOLUME adjusts the overall volume out of the pedal. LIFT gives an earth lift for the balanced XLR output.
But that’s not all. We included a mute switch and a green light to tell you when the output is on. Now when you’re not playing, you can just hit the mute switch and your microphone is silent.
The pedal has a center negative 9V DC socket for the power supply connection.
