I'm sure it's fine. But that conish ad copy...
Our low noise discrete component Class A pre-amplifier has been specifically designed to overcome the problems often encountered with amplification of Electric Instruments fitted with magnetic transducers. The usual cause of these problems is the mismatch of the impedance in the electrical circuit between the pickup and subsequent equipment: this mismatch has been completely eliminated with the introduction of our LD-3™ Line Driver/mute/Tuner Feed unit.
The input impedance is identical to a high quality tube amplifier and our Class A Pre-amplifier also features a highly effective RF filter which will help prevent interference from nearby radio transmitters.
