I've had this overdrive for a couple months now and it's truly an inspiring pedal.
You can dial a lot of different tones going from a mild overdrive to almost distortion like tones.
The spectrum knob is at first a bit weird to dial in, because instead of EQ'ing between low and high frequencies, it boosts low mid and high frequencies together. The higher the spectrumknob, the higher the boost of the two frequencies. It can be a brittle sound of you turn it all the way up.
I like to boost the spectrum just past noon, the drive quite high and slam the pedal with a boss OD3 to accentuate a bit more mids.
The basscut switch inside is a cool feature but does not make that big of a difference I think.
A useful thing on the Nobels ODR-1 is that the batterycompartment is reachable from the front, this is handy if you need to change a battery on your pedalboard during rehaersals. I wish more companies did this, a really nice touch from nobels.
All and all a very good pedal, it certainly deserves the love it gets from a lot of people on the internet. Great product!
