אפקט לגיטרה NUX NOD-2 TUBEMAN OVERDRIVE

Genuine Tube-like sound that makes it more than your average Tube Screamer!
More gain !  That was the overall goal.  If you’re not playing through a real tube amp, cranked for overdrive, it’s difficult to get  genuine tube overdrive sound.

The original Tube Screamer pedals used an OP-AMP system, a basic circuitry that became popular for its “perfect amp” attributes.  It had no distortion so it had to be overdriven or distorted by re-shaping the signal until it distorts ( diode-clipping ).  Clipping it a little bit gives you Overdrive.  Clipping it a lot gives you Distortion.
