Noble preamp clone This is a clone pedal of the Noble preamp. While retaining the excellent sound quality of the original, we have improved its usability. We have measured and compared the frequency characteristics of both the actual unit and the clone, and confirmed that they have almost the same characteristics. Power supply is DC12V (adapter included), added a thru-out, the DI out employs a high-quality transformer modeled after Jensen, equipped with a true bypass FSW, built-in two 12AU7 vacuum tubes driven at approximately 250v, and the circuit board was designed to be as compact as possible. Controls Top panel: Treble, rolloff sw, Bass, Volume from right to left Right side: Input, Thrue Out from top to bottom Left side: Output, DC12v IN, DI out, GND/LIFT SW, DI out Volume from top to bottom Treble and Bass are flat when turned fully counterclockwise. Turning them clockwise boosts Bass below 100Hz by up to +20dB and Treble above 2kHz by up to +20dB. Volume boost is +20dB. The rolloff (low cut) switch is on in the up position. It attenuates frequencies below 100Hz. Accessories Dedicated adapter (DC12V2A, center negative), instruction manual *Due to being a handmade product, there may be minor scratches. *FSW note: In the effect off state, there is no output from the DI out. This is a specification and not a malfunction. Please be careful not to use the FSW when using it as a DI BOX. We will repair any failures within one year of purchase free of charge, excluding power connection errors, modifications, and submersion. We also offer affordable repairs after the warranty period.
