The Cornish LD-1 is a Line driver dual voltage 9/18 VDC unit - a low noise discrete component Class A pre-amplifier that has been specifically designed to overcome the problems often encountered with amplification of Electric Instruments fitted with magnetic transducers. A frequent 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 the LD-1™ Line Driver. 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 LD-1™ input with a low loss, screened cable; the LD-1™ output can now be fed to any effects or volume pedals (if used) and then on to the amplifier, using fully screened cables throughout.
A further use of the LD-1™ is to isolate long cable feeds which can cause signal and tone losses at the end of an effects chain, particularly if the final effect has a high impedance output (for instance a 250KW foot volume pedal). When using many effects it can be beneficial to add a LD-1™ mid way along the chain thus preventing a build up of signal losses that can occur with mismatched impedances between effects.
