The Revv G3 Distortion Anniversary BK is a versatile distortion pedal based on the 'Purple Channel' from Revv's Generator 120 and 100P amplifiers, offering a modern, tight, and clear high-gain tone. This pedal is suitable for hard rock and metal, acting as a preamp with a 3-band EQ, and aggression switch for diverse tonal shaping. Its ability to work well with various amplifiers, pickups, and the ability to stack it with boosts like a TS808 makes it a recommended choice for players seeking a powerful and responsive distortion effect.
