Cornish Pedale LD3
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.
The pickup output should be connected directly to the Line Driver input with a short, low loss, screened cable; the Line Driver output can now be fed to any effects or volume pedals (if used) and then on to the amplifier, using fully screened cables, of any length, throughout.
Also fitted is an auxiliary output, which may be used to feed a signal to a Tuner; this signal is identical to the main Output signal but has additional isolation components to ensure that interference signals, which may be generated in a tuner, are not fed back to the amplifier. The Tuner Feed signal is permanently active.
The heavy-duty footswitch controls the signal sent to the main “OUTPUT” jack and provides a complete shutdown of the audio signal path when set to “MUTE”"
