The Electro-Harmonix Soul Preacher is a compact compressor/sustainer effect with variable parameters allowing extreme or subtle adjustments of the dynamic qualities of your playing. Two knobs and one 3 way toggle switch control the output volume, the depth of the effect and the attack/decay characteristics of the effect. The input sensitivity is 50mV to 2 volts, making it a perfect fit to most magnetic guitar pickups and active/buffered pickups. The preamp does add some distortion and the amount is level dependent. Humbuckers and high output single coil pickups will distort much more than normal single coil guitar pickups. This distortion can be controlled somewhat from the guitar’s volume level ahead of the compressor.
