Black chassis, white LED version! Noble preamp clone This is a clone pedal of the Noble preamp. While retaining the excellent sound quality of the original, we've improved its usability. We've measured and compared the frequency characteristics of both the real unit and the clone, confirming that they have almost identical characteristics. Power supply is DC12V (adapter included), added a thru-out, the DI out uses 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 Right side: Input, Thrue Out Left side: Output, DC12v IN, DI out, GND/LIFT SW, DI out Level 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. Rolloff (low cut) sw is on in the up position. It attenuates frequencies below 100Hz. Output is affected by the top panel Volume. DI out is affected by the side panel DI out Level. (The outputs each have independent volume controls) Included Dedicated adapter (DC12V2A, center negative), instruction manual *Due to being a handmade product, there may be minor scratches. *Regarding the footswitch, the output from the DI out is disabled when the effect is off. This is a specification and not a malfunction. *There may be a popping noise when switching the low cut switch, but this is a specification and not a malfunction. We offer free repairs for failures within one year of purchase, excluding incorrect power connections, modifications, and water damage.
