EBS is my fave octave for bass.
unlike perhaps 98% of other respondents, I am not merely listing the pedal I own. I don’t own an EBS, and there are a slew of competitors that are likely just as wonderful. But I’ve played it a number of times, and it is the octave I hear in my mind’s ear.
I've found uses for all three of the tone settings and at least 4 or 5 different useful sonic applications in band settings. The switch to change settings works well for my feeble decision-making capacity.
