I often play in a band with a singer, drummer and one guitarist and so need to find a way to thicken out what I'm doing sometimes. I've used octavers for ages and this is by far the best I've tried.
Construction is as good as you would expect from EBS - solid and strong. Tracking is excellent, even quite far down the fretboard. It's precise and clean - and the true bypass is useful. Controls are simple and do exactly what you think they would.
All in all, the best Octaver out there, I think
