Corey Congilio is a producer and instructor1. He is an endorser of Nobels pedals, and plays the ODR-1 and the ODR-Mini, both overdrive pedals1.
On the ODR-Mini, Nobels quotes him:
"The ODR-Mini faithfully recreates the classic ODR-1 sound so many of us are seeking. Try it at 18 volts and it will be nearly indistinguishable from it's iconic counterpart! Congrats to the Nobels team on a great design and price point that's in reach for guitarists of all varieties."
He also notes that running the ODR-Mini at 18 volts brings it close to the sound of the larger ODR-11.
