Thank you for purchasing a ModWright Instruments product. This unit is designed to
offer high performance and exceptional reliability.
The Ambrose One preamp offers high bandwidth, low distortion, and exceptional
musicality. We have designed this unit to allow the reproduction of recordings that is
