Piezo pickup preamp is a special high quality preamp for
elements in acoustic musical instruments.
preamp has a very high impedance input , this ensures that the high-impedance output of
the piezo is not getting loaded so the frequency response
of the pickup piezo gets much larger.The amp has no
frequency correction or tone control. This
preamplifier is straight frequency characteristic! Most
preamplifiers for piezo are colour tone controlled, this
results in not longer
matching the original sound of the instrument itself, they
have a totally different sound, those amps have no
straight frequency response.
tries to get the original sound as good as possible to
has two ouputs, one normal the other is 6db lower for
impedance are very low so inductance and capacitance of
almost no effect.
