I bought this pedal together with the Aguilar Octamizer, because those were the pedals I heard the most rave about. I ended up going for the Octamizer, and will explain why.
The Bass Octave Deluxe (BOD) is very lightweight, and has the in/out connectors and the power inlet on the sides. It is beautifully finished in a sparkly blue color, and despite its weight, feels very solid. It has three knobs; one to control the dry bass sound, and two knobs with their own specific octave sound. Blending these three sounds, you can get a lot different, distinct octave tones. It holds its octave to about the low A/G#, and sounds and tracks great in the lower registries.
The reason I ended up choosing the Octamizer over the BOD is the tracking in the higher registries. I use an octave pedal to keep a base when I play higher notes. In this area, I had some issues with the tracking of the BOD. It either glitched or played the wrong octave, especially with faster runs.
Purely sound wise, I think I prefer the BOD over the Octamizer, but in my case, the high registry tracking is an issue.
